The Specimens of Sitio Roberto Burle Marx

Posted in Interesting Plant Stories on June 11, 2019 by Matt Newman

Sitio Roberto Burle Marx, the eponymously named home of the iconic Brazilian landscape architect, was a haven of native Brazilian plants, from tropical bromeliads and philodendrons to orchids, legume trees, and more—many that he discovered himself. Discover just a few of the Brazilian specimens from the NYBG Herbarium that called the Sitio home, some even named for Burle Marx, in the latest from The Hand Lens.

With their exotic flowers and lush foliage, orchids are often considered the quintessential tropical plant, but as a recent publication from NYBG Press demonstrates, they are also native to the northeastern United States. Orchids (or Orchidaceae, their scientific name) are among the 27 plant families that are now available in the third installment of treatments released as part of the New Manual of Vascular Plants of Northeastern United States and Adjacent Canada by Robert F. C. Naczi, Ph.D., NYBG’s Arthur J. Cronquist Curator of North American Botany, and Collaborators. The family treatments have been published as individual, downloadable PDFs that can be viewed on a variety of devices such as a desktop computer, tablet, or smartphone.

In the region covered by the New Manual, there are 84 species of orchids, according to the treatment by Matthew C. Pace, Ph.D., Assistant Curator of the William and Lynda Steere Herbarium at The New York Botanical Garden, and John V. Freudenstein, Ph.D., Professor of Evolution, Ecology, and Organismal Biology at The Ohio State University.

Indian Pipes: The Parasitic Plants in Bloom at The New York Botanical Garden

Posted in Interesting Plant Stories on September 4, 2018 by Science Talk

Ashley Keesling is a graduate student at The Ohio State University who recently conducted a research visit to The New York Botanical Garden.

Intriguing and ethereal, Indian pipes (Monotropa uniflora) are often mistaken for fungi because of their pale, otherworldly appearance. Also known as ghost plants, they typically occur in well-established forests and are often thought of as indicators of healthy ecosystems—not the kind of plant you might think would grow in a dense urban area. However, pockets of preserved forests in New York City, such as the old-growth Thain Family Forest at The New York Botanical Garden, can allow species to flourish in unexpected places.

I came to the heart of the Bronx recently to hunt for Indian pipes in the Thain Forest as part of the research I am conducting for my master’s thesis at The Ohio State University.

These fascinating parasitic plants have been the subject of much interest over the years, including research by an early 20th Century NYBG scientist. Indian pipes are unusual in that they do not photosynthesize. Instead, they are mycoheterotrophic, meaning they obtain nutrients by parasitizing a type of fungi that associate with plant roots. These mycorrhizal fungi help the plants take up water and nutrients that might otherwise be inaccessible to the plants. In exchange, the plants provide the fungi with sugars created from the process of photosynthesis. Indian pipes take advantage of the relationship between another plant and its associated fungus and “steal” sugars from the fungus. This three-part symbiosis allows Indian pipes to ultimately get their nutrients from a photosynthetic plant through the means of a mycorrhizal fungi.

One of the most pressing challenges in botany today is inspiring and training the next generation of systematists, scientists who discover, name, and classify species. In January, an international partnership sought to address this need through a tropical field botany course held in Ecuador for eight graduate students. The program was designed to engage students first-hand with the exciting (and sometimes trying) nature of field collection that is foundational to systematics.

The course was organized by Gregory M. Plunkett, Ph.D., Director and Curator of the Cullman Program for Molecular Systematics at The New York Botanical Garden; Porter P. Lowry II, Ph.D., and M. Marcela Mora, Ph.D., of the Missouri Botanical Garden; and David A. Neill, Ph.D., of Universidad Estatal Amazónica (UEA) in Ecuador with help from Efrén Merino. Of the eight students, four were from the United States and four from Ecuador. They came together at the UEA field station called Centro de Investigación Posgrado y Conservación Amazónica (CIPCA) to learn the logistics of botanical field work, using the genus Schefflera (in the Araliaceae family) as an example. The students brought with them a variety of backgrounds and interests, including plant-insect interactions, lichenology, and conservation, but were eager to get their feet wet in tropical field botany.

Plants as Calendars

Michael J. Balick, Ph.D., is Vice President for Botanical Science and Director and Philecology Curator of the Institute of Economic Botany at The New York Botanical Garden, and Gregory M. Plunkett, Ph.D., is Director and Curator of the Botanical Garden’s Cullman Program for Molecular Systematics.

For most of us, calendars rule our lives. They allow us to organize our days, remind us of future appointments, and importantly, help us to carve out a space when we can take a break from the frenetic pace of life. Increasingly, they are stored on our computers or mobile phones, but this modern tool developed and evolved over a long period of human history.

Before the introduction of the Western calendar, people in Vanuatu reckoned time through their own observations of the natural world. Especially important were certain species of “calendar plants,” whose flowering or fruiting provided an indication of the change of seasons and cues for certain activities, such as gardening, hunting, and fishing. The use of plants as a guide for human activities is of great interest to us. During the past two years, we have been privileged to work with a team of people focused on understanding the diversity, distribution, uses, linguistics and conservation of the Vanuatu flora. Our work on the Tafean islands of Tanna and Aneityum involves collecting plants, mapping plant distributions, and gathering information on the local names of these plants and how people use them.

Hunting for Hamilton’s Sweetgums

Posted in Interesting Plant Stories on February 27, 2018 by Victoria Johnson

Victoria Johnson is an associate professor of Urban Policy and Planning at Hunter College of the City University of New York. Her biography of the botanist and doctor David Hosack—the attending physician at the Hamilton-Burr duel—will be published in June 2018 by Liveright, a division of W. W. Norton & Co. It is titled American Eden: David Hosack, Botany, and Medicine in the Garden of the Early Republic.

Alexander Hamilton considered himself a poor gardener.

In December 1802, he conveyed this fact to a friend in the most pointed way he knew how—via a political dig at President Thomas Jefferson, his longtime rival. Hamilton quipped that horticulture was a pursuit “for which I am as little fitted as Jefferson to guide the helm of the U[nited] States.”

When Hamilton wrote these words, he was facing an entirely novel challenge: laying out the grounds of his new country house in northern Manhattan. The Grange, as he called it, was a boxy yellow mansion on a parcel of about 35 acres he had purchased in 1800. From its piazzas, Alexander and Eliza could catch glimpses of the Hudson, East, and Harlem Rivers.

Tell Me Something I Don't Know
Dr. James Lendemer (standing) tells host Stephen J. Dubner (seated, center) and co-hosts A. J. Jacobs (left) and Sas Goldberg (right) something they didn’t know about lichens.

Readers with an interest in economics and listeners to public radio know Stephen J. Dubner as one half of the writing team behind the best-selling 2005 economics-for-everyman book Freakonomics and as the host of the program Freakonomics Radio.

A triple threat, Dubner is also the host of a game show podcast, Tell Me Something I Don’t Know, in which a handful of guests with a particular expertise talk to Dubner and his co-hosts about their subject and then the audience votes for its favorite expert. The prize: the satisfaction of winning and a nice commemorative certificate.

In a recent episode, “Farming without Sun or Soil and Manna from Heaven,” NYBG Assistant Curator James Lendemer, Ph.D., talked about his passion—lichens, combinations of a fungus and an alga that play important roles in ecosystems by filtering water and air and by providing habitat and food for wildlife.

As Dr. Lendemer explains, lichens are so sensitive that they are considered an indicator of air quality, but they are also tough enough to survive in outer space.
