Epifagus virginiana
Tree Mob™! At the Arnold Arboretum

A Unilateral Contract: Epifagus in the Beech Grove
Walking under the beautiful American beech (Fagus grandifolia) on a gorgeous afternoon seems a lovely thing. But do you know that a sinister thief may be present? This freeloader, Epifagus virginiana or commonly beechdrop, is a parasitic plant that forms delicate connections to the roots of American beech trees. The brownish plant has no leaves for photosynthesis and instead depends solely on the tree’s roots for nutrients and water. Zhenzhen Yang, who completed her dissertation at Pennsylvania State University on this monotypic plant, will speak about its life cycle and singular dependence on the American beech. Meet in the beech grove at Acc. # 14585*B on Sunday, October 23 at 2:00pm.

Join us for a Tree Mob™!

What’s a Tree Mob™?

Tree Mobs are interactions with scientists or other specialists at the Arnold Arboretum, and provide another pathway to enjoy and learn in the landscape. Experts share little-known facts about our living plant collection, its relevance today, and its importance to future generations. A Tree Mob may attract a small group or a large gathering—we won’t know until it takes place. Join us in the landscape and discover something new.

What can I expect?

Plan to spend approximately 30 minutes learning about an interesting component of our collection. You can then continue your exploration of the Arnold Arboretum on your own. Tree Mobs are time, date, and location specific.

How does it work?

We will communicate about Tree Mobs by various means (see below). Using mobile technologies, such as a smartphone with location-awareness enabled, you will be able to navigate to the event location. You can also view and print a map we will provide with the day’s Tree Mob location on our website. With directions in hand, proceed to the designated meeting place to participate in our experiment for spontaneous learning.
