Exploring the science of plants, from the field to the lab

Blast from the Past: Plant Specimens From One of America’s Cold War Nuclear Test Sites

Posted in Interesting Plant Stories on August 25, 2016 by Colette Berg

Colette Berg, an intern in the William and Lynda Steere Herbarium at The New York Botanical Garden, recently graduated from Fordham University, where she studied environmental science. In January, she will begin a Master’s in Biology program at Southeast Missouri University, focusing on plant ecology.

Every day as an intern at the William and Lynda Steere Herbarium, I transcribe the labels on pressed plant specimens so data about the specimens can be made accessible online. As I type out the collector’s name, date of collection, and location, I catch a glimpse of the stories behind the specimens—stories of science and politics and history.

Recently, one particular label caught my eye. In 1946, William Randolph Taylor, a University of Michigan botanist who specialized in algae, traveled to the Marshall Islands in the South Pacific with Operation Crossroads, a military mission to test atomic bombs at the remote Bikini Atoll. Taylor’s 1990 obituary described him as a man who “worked in the years of brass-fitted monocular microscopes” and “entered the sea in long rubber boots while holding a glass-bottomed bucket.” Before the bombs were detonated, Taylor surveyed the vegetation on the island. One can imagine him peering through his bucket in the surf as he collected some of the specimens shown here.

The Science of Stink

Corpse FlowerAh, New York in the summer. So many fetid fragrances fill the air. The garbage on the sidewalk, the hot blast of exhaust from a passing bus, the dank odor of the subway—these and even less savory sources best left to the imagination all add their odors to the city’s atmosphere on a hot, humid day.

That makes it all the more remarkable that thousands of New Yorkers have flocked to The New York Botanical Garden to see the corpse flower that is now blooming in the Enid A. Haupt Conservatory. Apart from its size and striking appearance, the plant is notable for its stench, often compared to the smell of rotting flesh, which is the clever ploy it has evolved to attract pollinators.

Perhaps the fact that the plant blooms so infrequently and unpredictably draws most people, but many seem fascinated by the phenomenon that something in nature would smell this bad on purpose.

Like other scientific research and educational institutions across the country, The New York Botanical Garden has seen increased enrollment in its Master’s programs in recent years as more graduate students pursue non-Ph.D. advanced degrees in the sciences. While many Ph.D. students seek careers in research and academia, Master’s students are more often looking for training opportunities to prepare them for careers in business, industry, nonprofit organizations, and government agencies.

To ensure that we continue to offer a broad range of opportunities to graduate students in the plant sciences, we have responded to this demand by providing Master’s thesis opportunities to students through our affiliated universities. Yale University’s School of Forestry and Environmental Studies offers four Master’s degrees, as does New York University, including one focused on bioinformatics and systems biology, which is very relevant for students who want to gain expertise in biodiversity-related data management. Lehman College and City College of New York—both part of the City University of New York system—offer Master’s programs in biology. Columbia University confers a Master’s in conservation biology, while Fordham University has a Master’s in ecology.

On a steamy day in late May, a crew of invasive species scouts assembled in the parking lot of the Garth Woods Apartments in Scarsdale, Westchester County. Our mission? To survey Garth Woods, a sliver of intact riparian forest, for Corydalis incisa, also called incised fumewort or purple keman. Much to our excitement, this case of sleuthing had a happy ending: for now, Garth Woods shows no sign of C. incisa, and full to the brim with uncommon native herbs that were a joy to see.

C. incisa, which is native to Asia, is an emerging invasive along the Bronx River; it was first recorded in the New York metropolitan region during the Bronx Park BioBlitz in 2005, and has subsequently been observed along the riverbanks of the Bronx River in The New York Botanical Garden and in several sites in Westchester County.

Watching some fireworks, going to the local parade, grilling burgers and hot dogs, maybe even finding time for a nap. Sounds like a classic Fourth of July. Collecting plant specimens is notably missing from this list. And yet, for botanists, our nation’s birthday is not necessarily a day off.

A search of the C. V. Starr Virtual Herbarium, where The New York Botanical Garden’s digitized herbarium specimens are made available online to researchers and the public, reveals that it includes no fewer than 6,808 specimens that were collected on a Fourth of July. They come from around the world, but more than 1,000 were snipped or dug up in the United States on Independence Day. They eventually found their way to the Botanical Garden’s William and Lynda Steere Herbarium, where they are now part of the 7.8 million specimens that are preserved there and are now being digitized for the Starr Virtual Herbarium.

The last scientific survey of the plants of Vietnam—written by two French botanists in 1937, when it was a French colony—led a team of researchers to expect that they would find about 60 species of palms when they began a research project in that Southeast Asian country in 2007.

To date, they have discovered 113 species, including 41 that are new to science, and an entirely new genus (a group of closely related species).

“Sometimes we can drive up a road and look out the window and see new species,” Andrew Henderson, Ph.D., Abess Curator of Palms at The New York Botanical Garden, told a group of Garden Members during a recent Britton Gallery Talk. “Vietnam was overlooked by biologists for a long time because of war.”

Esther Jackson is the Public Services Librarian at NYBG’s LuEsther T. Mertz Library, where she manages Reference and Circulation services and oversees the Plant Information Office. She spends much of her time assisting researchers, providing instruction related to library resources, and collaborating with NYBG staff on various projects related to Garden initiatives and events.


The New WildThe New Wild: Why Invasive Species Will Be Nature’s Salvation is the latest book from environmental journalist Fred Pearce.

In recent years, invasive species have been on the minds of many people and have been the focus of a variety of organizations working in ecology and biology, including The New York Botanical Garden. As Science Talk readers may know, the Botanical Garden hosted an invasive species summit in November 2015 to address the threat that invasive species represent to biodiversity worldwide. The summit featured discussion about conservation, including ecosystem management, and involved prominent speakers in the fields of invasion biology, restoration ecology, and not-for-profit land management. The New Wild is quite a topical book.

The Rock Gnome

Posted in Interesting Plant Stories on May 27, 2016 by Jessica Allen

Jessica L. Allen is studying for a Ph.D. as a student in the Commodore Matthew Perry Graduate Studies Program at The New York Botanical Garden. Lichens are her primary research interest.


ForestGnomes exist. They’re quite short and green with black caps. The only place to find them is on rocks in the southern Appalachians, and the best place to find them is in western North Carolina.

The gnome I’m describing is actually a lichen (which are combinations of fungi and algae) known as the rock gnome lichen (Cetradonia linearis). It’s one of two fungal species protected by the Endangered Species Act and a member of one of the largest families of lichens, Cladoniaceae.

The rock gnome was one of four fungal species recently added to the Red List, a list of endangered species all over the world that is maintained by the International Union for the Conservation of Nature. Before these four species were added, only two fungal species were recognized on the Red List. The rock gnome lichen was added to the Red List after a successful meeting at The New York Botanical Garden last summer, during which a group of lichenologists came together to prepare detailed assessments of North American lichens.

On Wednesday, June 15, 2016, from 1 p.m. to 6 p.m., the LuEsther T. Mertz Library will be hosting a Wikipedia Edit-A-Thon focused on creating and sprucing up pages for botanists who have made significant collections in New York State.

Editors are welcome to use the vast historic collections of the Mertz Library to create and edit pages. For those who aren’t familiar with Wikipedia’s editing process, we’ll be offering training to help you get started, and editors of all skill levels are welcome to join in.*

Index Herbariorum and KE EMu, the herbarium collections database at NYBG, were used as starting points to build a list of New York State’s most notable plant collectors. This field has been male-dominated, historically, so we’re making every effort to promote better representation of female botanists. Help us share their contributions with the world!

All you need to do to attend is R.S.V.P. here.

You can view this event on Wikipedia and add yourself to the event page here.

*Attendees must bring a laptop to this event. Please note that training for new editors will be offered during the first hour of this event. New editors should plan on attending this training. Experienced editors are welcome to arrive at any point during this event’s duration.

WFO at NYBG: Scientists From Around the World Meet to Advance Work on a Comprehensive Online Plant Database

Posted in Interesting Plant Stories on May 6, 2016 by Stevenson Swanson

World Flora Online New York Botanical GardenAs if assembling a comprehensive, scientifically verified database of more than 350,000 plant species were not a daunting task to begin with, try doing it in only four years. That’s the ambitious goal the scientists working on World Flora Online (WFO) are racing to meet.

When it’s up and running, WFO will provide scientists, conservationists, political leaders, and other policy-makers with information they need to protect one of Earth’s most important resources—its plants.

More than two dozen of the world’s leading plant scientists gathered at The New York Botanical Garden recently to review the progress that has been made on WFO and to plan the way forward so they can meet the goal of completing the database in 2020, which was established in the Convention on Biological Diversity, an international agreement.

As part of a week-long series of meetings at the Botanical Garden, several of the participants spoke about specific aspects of this monumental project during a symposium on Wednesday, April 27, in the Garden’s Ross Hall.

The presentations began with introductory remarks by Barbara M. Thiers, Ph.D., the Garden’s Vice President for Science Administration and the Patricia K. Holmgren Director of the William and Lynda Steere Herbarium. She noted that the Garden is one of four leading botanical institutions that are working together to coordinate the efforts of scientists and institutions around the world to create this first-of-its-kind online resource.
