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 termma 
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 mam 
axis or of the branch which has developed as strongly as the mam axis. 
The calyx is valvate. Stamens 15, of which 10 are episepalous, standing 
in 5 pairs behind each other. Anthers short, glabrous ; cells very unequd, 
diverging at the base; appendix of connective obtuse, often verj' short, 
those of the 5 inner much longer. Ovary either free or half immersed 
in the obconieal receptacle, often pitted, generally hairy; style cylmdnc, 
often ribbed and furrowed, mostly shorter than ovary; stigiiia capitate or 
conical. Segments of fruiting calyx either equal, shorter than fnnt, or
