Cibotium cumingii Kunze

Habit as in C. barometz, but fronds probably never quite so large; pinnules to 180 mm long, rarely over 20 mm wide, those on basiscopic side towards base of a pinna much shorter than those on acroscopic side (often less than half as long), distal pinnules and those of upper pinnae more equal; sori always one pair at the base of each fertile segment of a pinnule; hairiness of lower surface of costae and costules variable, usually some stiff spreading hairs (pale or reddish) present along with appressed flaccid hairs, in some cases either the one or the other kind predominating.
