Considering its size and location New England has a relatively rich flora of ferns and fern allies (clubmosses, spikemosses, and quillworts). While it is possible to see almost all these species somewhere in the state of Massachusetts, several can be found at the Arnold Arboretum. Fern specialist Jacob Suissa will teach the anatomy, reproduction, and key identifying characters that will help you to identify the ferns and fern allies of the Arboretum and New England. Participants will begin indoors at the Arboretum’s Weld Hill Research Building with a lecture and then move outdoors to Hemlock Hill and Bussey Brook for a fern foray. Dress for indoor and outdoor learning. The class will take place Friday, June 1, from 2 – 5 (originally scheduled for June 3, so take note.) Fee $40 Arboretum member, $50 nonmember.
