Aniseia hastata Meissner; A. stenantha (Dunn) Ling ex R. C. Fang & S. H. Huang; A. stenantha var. macrostephana Y. H. Zhang; Ipomoea setifera Poiret var. fimbriosepala (Choisy) Fosberg; I. stenantha Dunn.

Corolla purplish to red, with a darker center, narrowly funnelform, 2.5-4 cm, glabrous. Stamens included; filaments pilose below middle. Ovary conical, glabrous. Style filiform, ca. 5 mm; stigma capitate, 2-lobed. Capsule pale brown outside, whitish inside, ovoid to globose, 1-1.5 cm. Seeds black-brown, ovoid, ca. 5 mm, densely tomentellous.

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.
