I have also collected this same form in the neighborhood of the Si Bode River 
about 30 miles southwest of Sandakan, British North Borneo, in October 1908 
{no. 568).

VATICA Linn. 
Brandis (1. c. 118) characterizes the genus as follows: “Leaves as a 
rule coriaceous, petioles generally pubescent. Stipules mostly small, 
caducous. Secondary nerves distinct and limited in number, tertiary 
mostly reticulate. Flowers in spikes or racemes, not unilateral, arranged 
in terminal and axillary panicles. In some species there is what appears 
to be a cyme. The axis bifurcates, and there is an apparently terminal 
flower in the bifurcation. On closer examination it is found that what 
appears to be a terminal flower is the lowest lateral flower of the main 
axis or of the branch which has developed as strongly as the main axis. 
The calyx is valvate. Stamens 15, of which 10 are episepalous, standing 
in 5 pairs behind each other. Anthers short, glabrous ; cells very unequal, 
diverging at the base ; appendix of connective obtuse, often very short, 
those of the 5 inner much longer. Ovary either free or half immersed 
in the obconical receptacle, often pitted, generally hairy; style cylindric, 
often ribbed and furrowed, mostly shorter than ovary ; stigma capitate or 
conical. Segments of fruiting calyx either equal, shorter than fruit, or
