Ipomoea fimbriosepala Choisy

Ipomoea fimbriosepala is very similar in all respects to I. setifera Poiret, which is reported to have corollas 6-7 cm long and wider leaves. Chinese specimens come nearer to the descriptions for the former species. Fosberg (Smithsonian Contr. Bot. 36: 24. 1977) reduced I. fimbriosepala to a variety of I. setifera, but Austin (Fl. Venezuela 8(3): 159. 1982) maintained it as a distinct species. Ipomoea stenantha is placed here in the synonymy of I. fimbriosepala for the first time.
