- Morphology Reproductive morphology Flowers Androecium Stamens Filaments
- The lower filament (sometimes interpreted as an outgrowth from the nectary disc) develops into a curved scale The 5 Filament base scales arch inward and almost touch the style, the anthers encircle the style, dehiscing outward; this arrangement no doubt plays some role in pollination.
- Morphology Reproductive morphology Flowers Corolla
- The urceolate corolla has a unique spittoon shape.
- Morphology Reproductive morphology Fruits
- Fruits are dehiscent, 4 (or less by abortion) -seeded capsules.
- Morphology Reproductive morphology Inflorescences
- The subumbellate, many-flowered, head-like inflorescence almost sessile in the leaf axils is a good field character.
- Note
- Two African genera, Lepistemonopsis Dammer (1 species) and Paralepistemon Lejoly & Lisowski (2 species), each share with Lepistemon the feature of filament base scales, though neither occurs in Australasia. Lepistemonopsis is readily differentiated by its campanulate, 5-lobed corolla; and an indehiscent, or tardily dehiscent, 4-seeded fruit. Paralepistemon is readily differentiated by the cymose inflorescences in the upper leaf axils that form lax panicles; a broadly funnelform corolla; and indehiscent, woody, 1-seeded fruits. Wilkin's (1999) morphological cladistic analysis suggested that Lepistemon (and all the other spinulose pollen genera) should be subsumed into Ipomoea. Subsequent molecular evidence (Manos et al. 2001; Stefanovic et al. 2002) reached the same conclusion. Six species: one widespread in tropical Africa; one widespread in tropical Asia; two confined to the Indian subcontinent; one in eastern Asia; one in Malesia, Melanesia, and Australia.
