Behind the Doors of the Academy of Natural Sciences Herbarium: a Botanical Treasure Trove 200 Years in the Making

Alina Freire-Fierro, Collections Manager, and Tatyana Livshultz, Assistant Curator of Botany, at the Academy of Natural Sciences
If you’ve ever used an identification key, a flora, or a distribution map to learn something about a plant, you have, indirectly, accessed the treasure trove of botanical information housed in the world’s herbaria (collections of dried preserved plant specimens). Now botanical club members have the opportunity to experience a herbarium directly by going behind the scenes at the herbarium of the Academy of Natural Sciences, the oldest herbarium in the Americas, to see its operations and to learn about the history of herbaria and their vital function in science and conservation today.
The organizers need a head count to plan this event. RSVP by January 27 to Alina at 215-299-1157 or to philbotclub@gmail.com with the subject line “RSVP herbarium open house.”

Gesneriad-Hunting in China: Disappearing Mountains, White Bees, Venomous Caterpillars and Grandma’s Chirita

Stephen Maciejewski, President of the Liberty Bell chapter of the Gesneriad Society and Grant Coordinator for the Gesneriad Conservation Center in China
Join Stephen Maciejewski as he takes us on a 15-day journey into a seldom-seen section of China. Follow him and Professor Wei Yi-Gang, author of Gesneriaceae of South China as they travel 3,000 kilometers in search of beautiful, rare and still unnamed species of gesneriads. You’ll see plants never seen before: many Chiritas, other gesneriads and plants like the cave-growing iridescent blue Begonia edulis. Plus spectacular scenery, including otherworldly karst mountains, caves larger than ball parks, elaborate rice fields and quaint villages. And learn how a little caterpillar can have a unsettling effect on your plans. For those with a culinary interest, there’s marijuana soup, stir-fried white bees with ginger and a lovely green slime fungus with vegetables.
After the talk will be the annual holiday party, with wine and cheese.

Advancing Our Understanding of the Flora of the Northeastern U.S.A. and Adjacent Canada

Abstract: During the past two decades, botanical knowledge has increased considerably. Accordingly, The New York Botanical Garden has renewed its commitment to research on plants of the Northeast by embarking on a program to produce new resources for plant identification and geographic distributions. This presentation will review the Garden’s legacy in northeastern botany, explain the need for a new Manual of Vascular Plants of Northeastern U.S.A. and Adjacent Canada, and describe progress on the project.

The Bipolar Nature of Amelanchier (Rosaceae)

Michael Burgess, Research Botanist, Morris Arboretum
Commonly called shadbushes or serviceberries, the genus Amelanchier contains attractive shrubs to medium-sized trees that are closely related to apple, pear, hawthorn, cotoneaster, and mountain ash. Amelanchier is distributed across the North Temperate Zone and is most taxonomically diverse in North America. The taxonomy of Amelanchier has long been viewed as perplexing, as exemplified by Fernald, who stated that “no genus in North America, except of course Rubus and Crataegus, has offered so much perplexity and has such contradictory treatment as Amelanchier.” Indeed, polyploidy, which is coincident with asexual reproduction, and frequent hybridization, does induce significant taxonomic confusion in Amelanchier. However, despite this complexity, recent research has fundamentally reshaped our understanding of Amelanchier, and has revealed, for the first time, a dimension of the genus characterized by morphologically, ecogeographically, and genetically distinct taxa.

Dedication of the Benjamin Smith Barton Historical Marker

712 Arch Street, Philadelphia.

The Botanical Club, along with the Pennsylvania Historical and Museum Commission, and the Philadelphia Chapter of the Lewis & Clark Trail Heritage Foundation, will host a short ceremony at 2 PM to install a historic marker honoring the prominent botanist Dr. Benjamin Smith Barton, who wrote the first textbook on American botany. He died on December 19, 1855.

Barton was a faculty member of the University of Pennsylvania and a staff member of the Pennsylvania Hospital in 1803 when Meriwether Lewis came to our city at the behest of President Thomas Jefferson to prepare for an expedition across the American West.

Barton tutored Lewis in the collection, labeling, and preservation of plant specimens, resulting in the archival collection held today at the Academy of Natural Sciences.

The ceremony will be held at the location of Barton’s 1803 home: 712 Arch Street on the south side of Arch Street, about 195 feet from the 7th Street intersection.
