This plant closely resembles Guatteria {—Pohjalthia) clliptieu, Blume ; but its leaves
have more numerous neiwes and its carpels are stalked, those of P. cUiptica (according
both to Blume's description and figure) being sessile and of larger size.

The leaves of this species, although smaller, have much the same venation as those
of P. Teysmannii, King. The cai-pels of this are, however, very much smaller than
those of P. Teysmannii.
