Blume and Endlicber are inclined to separate O. pendulum, L. (Hook, et Grev. Je. Fil.
t. 19.) on account of the presence of an incomplete septum in the sporangia, and the different
habit; but the first of these two characters is very obscure ; the second is rendered
invalid by the intermediate nature of O. palmatum, (Hook. Ic. PI. v. 1 .1. 4.)
