A large tree, heartwood brown, hard and durable, on di-y ridges a shrub. 

 Leaiess during part of the hot season, when the tree is covered with large 

 panicles of showy flowers. Leaves ovate, whitish-tomentose beneath while quite 

 young. PL f in. across, petals orbicular, at flowering time foi^ming a hollow 

 globe, open at the top, enclosing stamens and ovary. Stamens 15, anthers 

 oblong, cells equal, the valves of each cell, as well as the connective, prolonged 

 into a short awn, so that each anther has 5 subulate appendages. Ovary glabrous, 

 prolonged into a conical stylopodium, style iiliform, glabrous. All calyx segments 

 enlarged in fruit, but the three outer much larger than the others, all narrowed 

 into a stalk, which expands into a broad base, appressed to the base of fruit, 

 but not enclosing it. Cotyledons thick, fleshy, stipitate, concave, enclosing 

 each other, filled with fat and oil, radicle short, plumula conspicuous.

Stipules in a few species large and persistent, in most small and early 

 deciduous. Leaves coriaceous, secondary nerves prominent, tertiary mostly 

 parallel. Plowers as a rule in unilateral spikes or racemes, which are distichous 

 and regularly alternating on the branches of large axillary and tex'minal 

 panicles. Each flower subtended by 2 bracteoles, mostly deciduous, in a few 

 species persistent and conspicuous, Sepals strongly imbricate, hairy. Petals 

 hairy outside. Anther cells generally equal ; connective as a rule prolonged 

 into a pointed appendage. Segments of fruiting calyx with their broad bases
