Stamens 10, unequal, one much larger than others; filaments connate at base. Ovary shallowly 3-lobed, 3-5 appendages on abaxial surface; style 1, rarely 2, filiform, at first circinate; stigma capitate.

Hiptage sericea J. D. Hooker is grown as an ornamental in SE Asia, with plants recorded in China from Guangdong ("Cape Syngmoon") and Taiwan.
We are unable to treat Hiptage leptophylla Hayata (Icon. Pl. Formos. 3: 48. 1913), described from Taiwan, because we have seen no specimens.
About 30 species: Bangladesh, Cambodia, India, Indonesia, Laos, Malaysia, Mauritius, Philippines, Thailand; ten species (seven endemic) in China.
