Notes
Hypserpa raapii was distinguished by DIELS from H. polyandra by the number of inner sepals being 4 in the former and 6 in the latter. H. raapii is still only represented by the solitary, male type specimen (RAAP 607) which does indeed usually have 4 inner sepals, but 5 also occur. Since (4-)5-7 inner sepals are found in H. polyandra, and RAAP 607 agrees in all other respects with that species it is not possible to maintain H. raapii as a distinct species.
This results in a rather curious distribution for H. polyandra, since RAAP 607 was collected in the Batu Is. west off Sumatra while H. polyandra is only known otherwise in S. and E. Malesia.
