Richard A. Howard1
Ignatz [Ignatius, on several publications] Urban was born in Warburg, a small town in eastern Westphalia, Germany, on January 7, 1848. As the son of a prosperous brewer he received a good education, first at the Gymnasium in his home town and then at the college in Pederborn, where he matriculated in 1866. While in college his interest in Botany was aroused by his teacher, Friedrich Wilhelm Grimme, and this was continued at the University of Bonn and the University of Berlin under the tutelage of Alexander Braun, Paul Ascherson, and Leopold Kny. His education was interrupted by military training in 1869 and by active service in the Franco-German war from 1870 to 1871. He returned to the University and published his first botanical paper in 1872. After receiving the doctor of philosophy degree in 1873, Urban took a position as a teacher in Lichterfelde, near Berlin, where he stayed until 1878. His published botanical work during this period concerned the local flora of Lichterfelde and a continuation of his doctoral work on the genus Medicago. After the death of Alexander Braun in 1878, W. A. Eichler was appointed head of the Department of Botany at the University of Berlin, and he in turn appointed Urban the head assistant in the Botanical Garden. Urban was promoted to curator of the garden in 1883. From 1889 until his retirement in 1913 at the age of 65, he served as assistant director of the botanical museum with the title of professor.
Urban's contributions are divided into three principal areas, each clearly revealed in his publications. As the assistant and later the curator of the botanical garden, he gave his attention to garden plants, to techniques of growing new plant introductions, to seed distribution, and to the history of the Berlin Botanical Garden. It was Urban who supervised the transfer of the botanical garden activities from the historical site in Berlin to the current site in Berlin-Dahlem. His knowledge of handling seeds and growing plants is revealed in his use of such material in his later work on the vegetation of the West Indies. As Eichler's assistant and eventual successor as editor of the Flora Brasiliensis, Urban made a second major contribution, his studies of plants of South America. Urban is credited with many contributions to the Flora Brasiliensis and with most of the editorial supervision which led to the completion of the publication in 1906. The Introduction to the Flora Brasiliensis which Urban prepared is often cited as one of the finest and most valuable surveys of its type. Third, to many botanists the series of publications called Symbolae Antillanae seu fundamenta Florae Indiae Occidentalis represents Urban's finest accomplishment, yet it is but one segment of a distinguished record of study and publication on the vegetation and the flora of the Antilles.
Urban's work on the West Indies was due in large measure to the influence and support of Leopold Krug. Krug was born in Berlin in 1833 in a prosperous and distinguished family. After completing his schooling he went to Bremen to be trained in a business career, which he started in Puerto Rico. Krug's business acumen is credited with his rapid rise to ownership of the firm in which he was first employed. He also married the daughter of a wealthy landowner, and thus his personal and business successes provided him with leisure time to devote to a personal hobby of zoology. Through a friend, Domingo Bello y Espinosa, whose profession was law, Krug's interest broadened to include plants. Together the lawyer and the businessman made collections and notes on the local flora and fauna. They attempted to identify the plants encountered with the aid of the works of Grisebach, de la Sagra, and De Candolle, but had little success.
As their collections also proved difficult to maintain in the tropics, Krug decided to supplement their observations with drawings from nature, and he eventually produced 340 plates giving the habit, the color of the flower and fruit, and often analytical drawings of the plant parts. When Krug returned to Berlin in 1876 he sought aid at the Botanical Garden and Museum for the identification of his material. Dr. Fritz Kurtz was the first to attempt to assist Krug. Although the amount of West Indian material in the museum was small, it did include the first ten centuries of Egger's exsiccatae from St. Thomas, Dominica, Trinidad and Puerto Rico, which had been identified at Copenhagen with the aid of the Vahl herbarium specimens.
In 1881, to the surprise of Krug, his former companion, Bello y Espinosa, published in the Anales de la Sociedad Española de Historia Natural, Madrid, the first part of his "Apuntes para la Flora de Puerto Rico." A second part was issued in 1883. This material had been envisioned by Krug as a joint publication, and toward this supposedly collaborative effort he was still working. The "Apuntes" as it appeared, contained many changes from their joint effort and made no mention of Krug or of his contributions. Although new taxa were described, no specimens were cited. The descriptions were meager, and no reference was made to Krug's more detailed drawings.
In 1884 Kurtz emigrated permanently to Argentina, leaving to Urban the privilege of working with Krug and his material. Apparently Krug and his family were anxious to remove the reflection they felt had been cast on Krug's botanical efforts, and so they supported financially the goal Urban then set to enlarge the West Indian herbarium and to complete a sound study of the Puerto Rican flora. The collections of Krug and Bello had been made in the western end of Puerto Rico at a low elevation. As a first step, the plant collector, Paul Sintenis, was hired to collect plant specimens, with emphasis to be placed on the mountainous areas. Sintenis arrived in Puerto Rico in the fall of 1884 and collected until June of 1887, during which time he gathered 8450 numbers of pteridophytes and flowering plants. The best specimens were kept in the Berlin herbarium and the duplicate sets were sold. It is not clear if Urban ever knew that many of the specimens "collected" by Sintenis and distributed from Berlin proved to have spurious origins and data. In any case the funds obtained by the sale of duplicate specimens identified by Urban were used to further the collection of plant specimens on other islands.
It was about this time that Baron von Eggers retired from military service. Eggers had previously collected and written of the plants of the Danish islands in the Antilles. Urban, using Krug's financial support, offered to subsidize Eggers on further botanical explorations starting with a trip to the high mountain areas of Hispaniola. Through this collection, a total of nearly 4500 numbers of plant specimens was received. Eventually Eggers also presented to the Botanical Museum his personal herbarium which contained rare and unusual species of his very early collections.
To these Urban was able to add many other collections obtained by purchase and by exchange. An impressive report of the collectors whose specimens were represented in the Krug and Urban Herbarium is included in the obituary of Krug which Urban published in 1898 (Ber. Deutsch. Bot. Ges. 16: 23-37. 1898). Krug and Urban managed to acquire a large set of the collections of Charles Wright, 1100 numbers of Bertero's collections from the Kurt Sprengel herbarium, numerous collections by Meyerhoff, de la Sagra, Torralbas, Weinland, Sauvalle, Spengel, Tillson, Jacquemont, Prax, and many others, which totaled over 12,000 numbers.
The contributions of Leopold Krug to this herbarium were material as well as financial. Urban recorded 1554 numbers that are credited to Krug, although these do include the collections made by Gundlach in Puerto Rico. [Gundlach, a professor of zoology, had been Krug's guest in Puerto Rico in 1875-1876, and during this time he collected plant specimens which Krug transferred in his own name to Berlin.] Among his most valuable contributions to the Krug and Urban herbarium were two catalogues. One of these was an annotated set of folders, each concerning the scientific name of one species in the West Indies. The second catalogue was a compilation of the vernacular names of West Indian plants. Krug's collection of 340 colored illustrations of Puerto Rican plants was also in the herbarium. In addition, Urban claimed to have obtained from Krug a handwritten copy of the third volume of MacFadyen's Flora of Jamaica, which was never completely published.
After Krug's death, and even after Urban's retirement, the additions to the herbarium continued. Urban collaborated in the study of the Cuban and Hispaniolan collections of Erik Ekman, and the Guadeloupe and Martinique collections of A. Duss; supported the collecting efforts of W. Buch and M. Fuertes; exchanged plants with N. L. Britton in New York, W. Fawcett in Jamaica, and other botanists in England and Trinidad. Urban was a prolific correspondent who never hesitated to write and request a fragment of a type specimen of a species he was studying. The postal cards in a meticulous hand were written in German except during a few years of the first World War, when Urban's correspondence was in English. The cards in many correspondence files or on herbarium sheets remain of great value in interpreting some of Urban's botanical decisions. While Urban was liberal in his requests for fragments, he was equally generous in supplying fragments or volunteering them. To aid the work of Wilhelm Buch in Haiti, Urban sent a complete set of fragments, often from type material, representing all the rare, unusual, or poorly collected species for Buch's study. With the destruction of nearly all the Krug and Urban herbarium in the Berlin fire during World War II these scattered fragments are all that remain of authentic material of many species of the West Indies.
The full size of the Krug and Urban herbarium was never revealed by its collectors. In 1922, in response to a request from B. L. Robinson, Urban placed a value of $20,000 on just the duplicate specimens in the herbarium. Urban indicated that he had given the herbarium to the State and, while he could sell the duplicates, the proceeds would go to the government and be of no personal help in spite of the hardships he was suffering from inflation.
Urban's early work with Krug on the West Indian flora was done while he was also responsible for work on the Flora Brasiliensis. Although the two floras presented similar problems and often concerned the same literature or the same species, the progress that Urban was able to make on each flora is astonishing. In 1886 Urban published the first of the papers he devoted primarily to collections from the West Indies. "Kleinere Mittheilungen über Pflanzen des Berliner Botanischer Gartens und Museums II" (Jahrb. Bot. Gard. Berlin 4: 241-259. 1886) contained notes of Krug on Dacryodes hexandra Griseb. which corrected observations by Bello; a description of Marcgravia sintenisii and one of Simarouba tulae from Puerto Rico, In 1892 the first number of the series "Additamenta ad cognitionem florae Indiae occidentalis" appeared in Engler's Bot. Jahrb. 15: 286-308, a series to consist of four parts, each describing many new taxa from the area. The genus Krugia, named in honor of Leopold Krug was published in 1893 by Urban as a single paper (Ber. Deutsch. Bot. Ges. 11: 375. 1893). A third series of two papers, which was first entitled "Diagnosen westindischer Arten" and later "Plantae novae antillanae" was published in the Notizbl. Königl. Bot. Gart. Berlin in 1895 and 1897.
In 1898 Urban published the first fascicle of the Symbolae Antillanae which ran as a series through nine volumes, the last published in March of 1928, There is very little information available concerning the series. Why it started, why it did not contain all of Urban's publications on the West Indies, or why it stopped are not clear. The many letters from Urban in the historical files of the herbaria at Harvard or at the New York Botanical Garden contain very few references to the Symbolae. In contrast to the information available for other journals, there are no notices of publication, no bills for the copies, or statements of price changes. Even in other botanical and horticultural journals of the period there are few notices of the Symbolae or reviews of its various issues. In a preface to the first volume, Urban stated that either the separate papers in the journals he had previously used for publication were not available to the botanists in the West Indies, or the volumes themselves were too expensive for them. He also suggested that his published work would sometime return to the series of papers he had established. Perhaps the original intent was to sell each fascicle of the Symbolae at a profit and thereby support the work of the Krug and Urban Herbarium. The first two volumes, however, contain evidence of pre-publication of portions of fascicles as reprints. Although Leopold Krug died in April of 1898 and the first fascicle of the Symbolae appeared in November of that year, he must have been a supporter of the work. In correspondence with B. L. Robinson, Urban credits a son of Krug with the continuation of some financial support of the series. In the first three volumes of the Symbolae, Urban published a particularly valuable synoptical review of the collectors, the authors, and the publications that concerned the flora of the Antilles, as well as miscellaneous papers as monographs or descriptions of new species. It is probable that the historical reviews were not acceptable to the editors of the standard periodicals in which Urban had published previously. The fourth volume of the Symbolae contained a flora of Puerto Rico and was dedicated to Leopold Krug. It was issued in four fascicles between 1903 and 1911. Although it contained no descriptions or keys to the taxa, the synonymy given has been basic to all subsequent work on the plants of the island. During the publication of this flora, six fascicles containing volumes five and six of the Symbolae were also issued. Volume seven comprised four fascicles issued between 1911 and 1913. Urban retired in 1913, shortly before the outbreak of World War I. In 1914 he began a series called "Sertum Antillanum" with the first number in volume 13 of Fedde's Repert. Spec. Nov. Regni Veg. This series comprised 30 numbers and concluded in 1930, just before Urban's death. The Symbolae was resumed with volume eight, a flora of Hispaniola, issued in 1920 and 1921, and was concluded with volume nine, the last fascicle of which was issued in 1928.
Upon his retirement Urban was able to devote even greater amounts of time to his work on the plants of the West Indies. He was receiving specimens regularly from Padre M. Fuertes in Barahona and W. Buch in Port-au-Prince. These, considered with the collections of H. F. A. von Eggers, H. von Türckheim, suggested that even more active exploration was needed. A young Swedish botanist, Erik L. Ekman, who had collected grasses and composites in Argentina, had come to Urban's attention through an application for fellowship support of work in Brazil (Howard, Bull. Torrey Bot. Club 79: 80-95. 1952). Urban arranged that the Swedish fellowship awarded Ekman be used for collecting in Haiti, and although this was not with Ekman's approval, it began one of the most profitable associations recorded of field botanist and herbarium taxonomist. Ekman arrived in the Western Hemisphere at the outbreak of the first World War and could not reach Haiti. Instead he visited Cuba. His first collections were described in "Sertum Antillanum III" while the majority appeared as the series "Plantae cubenses novae vel rariores a clo. Er. L. Ekman lectae" in volume nine of the Symbolae Antillanae. He finally reached Haiti in 1917, and the scientific report of the collections of this expedition was treated as a list of additions to the flora and published in the Ark. Bot. (Stockholm). Urban described Buch's collections as "Novitates haitiensis" in the Notizbl. Königl. Bot. Gart. Berlin. A Danish expedition to Beata Island collected plants, and these were described in a separate paper in the Dansk Bot. Ark. A classic investigation of the pre-Linnaean publication of Charles Plumier was issued as a Beiheft to Fedde's Repert. in 1920. A flora of Hispaniola consisting of two fascicles of 480 and 380 pages was published in 1920 and 1921 as volume eight of the Symbolae. Ekman's collecting continued and was intensified by this publication, and the records of new species formed series of papers which became "Plantae haitienses et domingenses novae vel rariores." The tenth and last part of this series in the Ark. Bot. was issued three months after Urban's death. Before the time of Urban's death, Ekman was ordered to stop his work in Hispaniola and begin again in Venezuela. In characteristic fashion he delayed his departure, and his last collections from Hispaniola are less thoroughly reported and many remain unidentified. On his 80th birthday in 1928 Urban was honored with the unveiling of a bust of his figure at the Botanical Museum. His colleagues around the world had been solicited for donations to create this memorial. Urban continued his work, appearing regularly in his laboratory until a few weeks before his death on the morning of his 83rd birthday in 1931.
The Symbolae Antillanae is one of the most comprehensive of publications on the flora of one small area of the world. It is equally unusual in being largely the work of one man. Although it was prepared under earlier rules of botanical nomenclature and not all parts are currently acceptable, the accuracy and completeness of the descriptions, the citations, and the references make the work of current as well as historical value. Urban's contributions on the plants of the Neotropics appeared in such a vast number of periodicals and series of papers that the ideal single complete index is not possible. The nine volumes of the Symbolae Antillanae are the largest segment of his work that can be handled in one cumulative index. It is published as an aid to easier work on the Antillean flora, and in respect and appreciation for the accomplishments of Ignatz Urban.

1 "Ignatius Urban and the 'Symbolae Antillanae'" [original title] by R. A. Howard first appeared as the introduction (pp. 1-6) in A cumulative index to the nine volumes of the Symbolae Antillanae seu fundamenta Florae Indiae Occidentalis edited by Ignatius Urban, compiled and prepared by E. Carroll and S. Sutton, Introduction by R. A. Howard. 1965. Arnold Arboretum of Harvard University: Jamaica Plain, Massachusetts. It is published here, with very minor changes, with permission of the author and of Arnold Arboretum of Harvard University, Cambridge, Massachusetts, U.S.A.
The world's largest and best studied collection of West Indian plants was kept at the
Botanical Museum Berlin-Dahlem (B) in the 1930's. This statement given with regard to the Herbarium Krug & Urban by Loesener (1931: 214) in his obituary on Ignatz Urban was, unfortunately, only true up to March 1, 1943,
when the greater part of the old holdings of this herbarium were destroyed by fire in a bombing raid. The opinion
that the herbarium was totally destroyed is wrong, even if it was widely circulated during the first decades after
World War II. It was estimated that about one-half million (of 4 million) specimens were saved and among this remaining
stock there are at least single specimens from nearly all old collections, especially among the surviving 20,000
types of the General Herbarium.
Comprehensive lists of the collections kept at B are given by Urban (1916) and Hiepko (1978, 1987). In his geographical index Urban (1916: 432 f.) lists the following collectors from the Greater Antilles: Alexander, Bertero, Bredemeyer, Britton, Buch, Caldwell & Baker, Christ, Combs, Churchill, Curtiss, Eggers, Ehrenberg, Favrat, Fuertes, Garber, Greene, de Grosourdy, Gruner, Gundlach, Hansen, Harris, Harshberger, Hart, Heller, Heuser, Humboldt & Bonpland, Jacquemont, Jaeger, Krause, Krug, Kuntze, Ledru, Linden, MacNab, March, Mayerhoff, Millspaugh, Morales, Moritz, Müller, Nash & Taylor, Nectoux, Otto, Palmer & Riley, Picarda, Plée, Poeppig, Poiteau, Prax, Prenleloup, Pringle, Purdie, Read, Rehder, Richard, Riedlé, Rothrock, Rugel, Sagra, Schomburgk, Schumann, Schwanecke, Shafer, Sintenis, Stahl, Stenzel, Swartz, Taylor, Torralbas, von Türckheim, Underwood & Griggs, Wilson, Wolff, Wright, Wullschlägel, Wydler, Xavier. Most of their collections were assembled in the Herbarium Krug & Urban which later continuously expanded by the collections of E.L. Ekman who added more than 24,000 numbers. The Herbarium Krug & Urban was kept separate until the death of Urban who, after retiring in 1913, has worked exclusively on the plants from the West Indies up to 1930. When the collection in 1933 was filed into the General Herbariumit consisted of 790 fascicles2. The building of this big herbarium started when Leopold Krug asked Urban in 1884 for aid for the identification of his plants collected in Puerto Rico. Krug, born in Berlin in 1833, lived as businessman from 1856 to 1876 in Puerto Rico. During this time he made collections and notes on the local fauna and flora. Finally his Herbarium Portoricense included 1554 numbers and he made 340 colored illustrations of plants (these illustrations, as well as Krug's two catalogues concerning scientific and vernacular names of West Indian plants, have been destroyed in 1943). Since the collections of West Indian plants in the Berlin herbarium were very poor at this time, Urban asked Krug for financial support to enlarge these collections as a sound base for the study of the flora of the Antilles. The first paid collectors were P. Sintenis and Baron von Eggers. A detailed report on the Herbarium Krug & Urban is included in Urban's obituary on Krug (Urban, 1898). Howard (1965) gives an impressive survey of the co-operation of Urban and Krug in the study of the West Indian flora. The surviving parts of the old Berlin herbarium are composed of the following (only examples relevant for the Flora of the Greater Antilles are given; for further details see Hiepko, 1987):
The very important historical Herbarium Willdenow (B-W) was also saved. Besides the types of the numerous species described by Willdenow himself, there is type material of many other species described by his contemporaries. In connection with the Flora of the Greater Antilles the following collectors represented in B-W are of special interest: F. Bredemeyer (180 specimens from Haiti, Puerto Rico, and Venezuela, 1785-1788), P.A. Poiteau (140, Haiti, 1796-1801), L.C. Richard (200, Antilles and N-America, 1786-1787), and O. Swartz (500, Haiti etc., 1784-1785). Specimens of the Herbarium Willdenow are not sent on loan, but we provide photographs or xerox-copies; there is a published alphabetical index (Hiepko, 1972) and the herbarium is available on microfiche (IDC 7440). The rebuilding of the general herbarium after World War II was only possible through generous gifts from friendly institutions and botanists from Germany and abroad. Sources of new material from the West Indies were many specimens sent as gifts or in exchange from American herbaria, especially from NY and US, and from the Swedish Museum of Natural History, Stockholm (S, 270 duplicates leg. Ekman). We received 179 plants from Cuba collected by W.H. Hatheway in 1954 as a gift. In 1993 the herbarium of the Humboldt University in Berlin (BHU) was transferred to the Botanical Museum (B). It includes ca. 23,000 specimens from Cuba, the third set of the "Proyecto Flora de Cuba (PFC)"-series of about 70,000 numbers (in HAJB, JE, and B), originally a joint project of the Jardín Botánico Nacional and the Academia de Ciencias de Cuba, the University of Jena, and the Humboldt University.

2 Fascicle: a bundle of herbarium sheets between two cardboards tied with a strap. At those times the herbarium sheets were kept in that way. It is not easy to estimate the number of sheets included in one bundle. There may have been 80-100 sheets included in one bundle. Urban (1916): 122) mentioned that in 1913 Herb. Krug & Urban was composed of "749 dicke Mappen" (749 thick bundles), thus the collection consisted of 60,000-75,000 sheets. For 1933 (Anon., 1934), about 790 bundles are mentioned; there may have been ca. 80,000 sheets or more (after 1913, ca. 20,000 specimens collected by E. L. Ekman arrived at Berlin).

A cumulative index to the nine volumes of the Symbolae Antillanae seu fundamenta
Florae Indiae Occidentalis edited by Ignatius Urban compiled by Eileen Carroll
and Stephanne Sutton.
The Arnold Arboretum has donated copies of this paper-cover book, with an introduction by Richard A. Howard, published in 1965. We are making the book available for the cost of shipping. The cost depends on the destination and how (book-surface mail or book-air mail) it will be sent. The following schedule indicates the cost:
Book/surface: U.S.A. and Canada $3.00; Europe, Caribbean, Mexico, South America, Asia, and Australia $4.00
Book/air: Canada $5.00; Europe $9.00; Caribbean and South America $7.00; Mexico $6.00; Asia $10.00; Australia $11.00
This volume is a good companion piece to use with Urban's Symbolae Antillanae, because it is a cumulative index to all titles and authors of articles, Latin names, common names, and publication dates for all the volumes. The introduction about Urban and his Caribbean work is the best available (and is reproduced as the lead article in this newsletter). To order the book, send your name and complete mailing address plus the correct shipping costs in US$. Checks should be drawn on a U.S. bank and made payable to The New York Botanical Garden. Otherwise, send U.S. cash. Send your order to T. Zanoni, New York Botanical Garden, Bronx, NY 10458-5126, U.S.A. Since the volume is being offered for only the cost of shipping, only prepaid orders will be filled.
