times accompanied or replaced by stellate hairs mixed with long simple 

 setae, 3-celled : ovules solitary in each cell ; styles 3, 2- or 3-partit8, 

 sometimes each branch again 2-partite, occasionally the arms again 

 2-fid. Capsule lepidote or pubescent and hispid, breaking up into 

 3 2-valved cocci. Seeds oblong, estrophiolate, brown overlaid with grey 

 or yellowish blotches. — Shrubs, rarely small trees, with lepidote or 

 occasionally stellate pubescent twigs. Leaves usually short-petioled, 

 rather large, more or less lepidote when young, alternate, scattered or 

 rarely clustered at the ends of twigs, alternate, entire, penninerved, 

 with two large glands on the upper surface at the point of junction 

 with the petiole ; petiole lepidote and sometimes also stellate-pubescent, 

 rarely setose ; stipules large, ovate, acuminate, lepidote or stellate- 

 pubescent and sometimes also setose, deciduous. Flowers in long axil- 

 lary interrupted spike-like racemes often exceeding the leaves ; bracts 

 small, usually 2-glandular. Male flowers usually shortly rarely dis- 

 tinctly pedicelled, glomerulate or on short clustered spikelets densely 

 clothed with' imbricating bracteoles ; females solitary, less often in 

 pairs, with long stout pedicels, generally on upper part of racemes only.
