Morphology
Horsfsieldia carnosa is a well-characterized species, a small tree of kerangas or peat swamp forest, on white sandy soils. It is distantly related to H. glabra, which is distinguished by a less stout habit, dark twigs, bark not tending to flake, smaller and usually membranous leaves, globose male flowers, pedicels ± articulated, globose or ellipsoid androecium with short androphore, and somewhat longer, not densely clustered fruits, 1.8-2.4 cm long.
