Formosan species of Tricyrtis were revised with special reference to T. formosana and T. lasiocarpa which are closely related to each other. T. formosana has the septicidally dehiscing capsules and the larger seeds (2-3 mm × 1.5-2 mm), while T. lasiocarpa has the capsules whose thin pericarp splits laterally and the small seeds (1.5 mm × 0.5 mm). The most important key character to indicate T. lasiocarpa is the presence of bristles on ovary though the density is not constant. The plants bearing bristles densely on the ovaries have larger and broader leaves, and the plants bearing bristles sparsely have narrower leaves. The latter form is less common and has the septicidally dehiscing capsules. There are plants of this form with high frequency of abortive pollens. In conclusion, the treatment of S_<HIMIZU> (1962) is supported here except for T. formosana f. glandulosa which should be reduced to f. formosana.
