Notes
A collection from Sumatra (Tenajan R., Upper Riouw, SOEPADMO 154) of which the leaves and also the fruit somewhat resemble the Bornean S. rubrinervis, but of which the panicle is like the Malayan S. laxa var. sericea, might be a new variety of S. laxa, but better material is needed to reach a definite conclusion whether this species occurs also in Sumatra.
