Peninsular Thailand; in Malesia: Sumatra, Peninsular Malaysia, Singapore.


Horsfieldia sparsa is distinguishable from similar species with pale twigs as, e. g., H pallidicaula and H. sucosa, by stoutness of the twigs, dispersed and ± chartaceous leaves, sometimes crowded towards the thickish, short, apical leaf bud, and relatively long petioles; also by the nearly glabrous inflorescences, the 3- or 4-lobed flowers, the not or only indistinctly articulated male pedicels, and the rather distinctly stalked androecium (androphore), generally without an apical cavity. Dry fruits reach 5.5 cm; according to the field labels fresh fruits may reach up to 11 cm, with thick fleshy-juicy pericarps, which obviously shrink considerably on drying. Horsfieldia pallidicaula differs in a sessile androecium; H. sucosa has articulated pedicels.
