When fading sunlight and perhaps a frost have shriveled the undergrowth and turned it brown, evergreen ferns and club-mosses stand out in dramatic contrast. On a Sunday, October 3 walk with New England Wild Flower Society’s Don Lubin and Raymond Abair through the Blue Hills Reservation, visit a dozen evergreen species and other pteridiphyte taxa, including polypody, Christmas and grape ferns, five wood ferns and maybe a spleenwort, four club-mosses and a horsetail. Travel about two miles on mostly flat trails with a few hills. A hand lens is suggested. $28 for NEWFS members, $32 for non-members. Meet at Blue Hills at noon.
