“…B . geniculata differs from other species of the genus in that spermatangial branches have a sterile apical portion (Hudson and Wynne 1969). Male gametophytes cultured from tetraspores of the fieldcollected tetrasporophyte bear spermatangial branches with sterile apices.…”

“…geniculata bear vesicle cells. Hudson and Wynne (1969) did not record this cell type in their study of gametophytes of B . geniculata, as their material was preserved in formalin making these cells difficult to see.…”

“…B o n m i s o n i a geniculata Gardner is a rare, epiphytic species collected, since its description (Gardner 1927), only as drift specimens. Based on four or five collections, the range of this species is believed to be from Point Sur, Monterey County (the type locality), north to Mendocino City, Mendocino County, California (Hudson and Wynne 1969 Kornmann and Sahling 1962) and B. ,nootkana (Chihara 1965).
