Lianas. Leaves palmately nerved at base with small papillose region on upper surface above insertion of petiole; Inflorescences axillary or cauliflorous, paniculate with lateral branches spicate or subspicate.


Asia-Temperate: Hainan (Hainan present), Asia-Tropical: Malaya present; New Guinea present, S. Thailand present
Two species in Hainan, S. Thailand, Indochina; in Malesia: Malaya to New Guinea.


There are clearly two species: the wide-spread, small-fruited A. flava and the large-fruited New Guinea endemic A tympanopoda, which can unfortunately only be identified in fruiting condition. Miss WILKINSON (l.c.) found that there are stomatal-anatomical differences in the leaf; FERGUSON (l.c.) found no difference in the pollen.
There is no indication that A. tympanopoda occurs outside New Guinea.
