Congratulations to “imachayes,” producer of wondermyway.com blog, for being the first (of many) readers to correctly identify the most recent Mystery Photo as a Beechdrops flower. A fairly inconspicuous brown stem produces two types of flowers, cleistogamous flowers that self-pollinate without ever opening, and chasmogamous flowers that open, but are often sterile. Those that are not sterile are pollinated by ants as well as other insects.
Beechdrops (Epifagus virginiana) is a flowering plant that lacks chlorophyll and thus cannot photosynthesize and make its own food. Instead, this plant obtains nutrients from American Beech trees. It belongs to a family of plants (Broomrape) whose members live as root parasites. Beechdrops insert a root-like structure called an haustorium (see photo inset) into an American Beech tree’s root and absorb enough nutrition to sustain themselves and produce flowers between August and October. Being annuals, Beechdrops don’t live long enough to damage their host trees.
Because they lack chlorophyll and obvious leaves (their leaves are scale-like and pressed flat against their stem), Beechdrops are easily overlooked. Keep an eye on the forest floor near American beech trees for these 5 – 18-inch plants which are flowering right now.
