The history of exploration and the collection of plants for scientific study in the Greater Antillean Islands is often dated back to the voyages of Father Charles Plumier and his companion Surian. An interpretation of his often excellent drawings has been attempted over the years and we currently await the conclusions of Dr. Alicia Lourteig, who plans a reproduction and identification of the original plates. The work of Olof Swartz is equally important and his specimens are primarily within the collections at Stockholm and the Natural History Museum (formerly the British Museum). Collaborative efforts involve recognition and designation of types in this material. Ignatz Urban of Berlin and Nathaniel Lord Britton in New York collectively spent 73 of their 110 years of botanical study on specimens from the Greater Antilles. Urban’s work began earlier and is presented in the nine volumes of Symbolae Antillanae and many papers in other series. A feature of the Symbolae work is a checklist of plants of Puerto Rico and one of Hispaniola.Urban also treated the collections of Erik L. Ekman made over a period of 17 years in Cuba, Haiti, and the Dominican Republic. Nathaniel Lord Britton with administrative responsibilities as director of the newly formed New York Botanical Garden completed much personal field work in the Antilles and directed and supported the collections of others. Thirty papers in one series of studies were published in the Bulletin of the Torrey Botanical Club. Britton published floras of Bermuda, the Bahamas, and with Percy Wilson the Botany of Porto Rico and the Virgin Islands. His unpublished work includes checklists of the floras of Cuba, Jamaica, and Trinidad. In Volumes 1 and 3 of the Symbolae Antillanae Urban gave brief summaries of the literature of the Greater Antilles and of the collectors up to 1900. The published version of this oral presentation will list the collectors of the 20^th Century following Urban’s format for each of the islands and also the primary collectors of the major groups of plants and fungi. The extensive list of names is derived from the databases of herbarium collections at The New York Botanical Garden and at the Harvard University Herbaria with help from other botanists.
