^ Flowers regular, polygamous. Sepals 4 or 5, imbricate in tlie Lud. Petals 

 either as many as sepals, small, with or without scales inside, or none. Disk 

 usually annular. Stamens usually 8 to 10, inserted inside the disk- fila- 

 ineuts short, rarely as long as the calyx. Ovary 2- or 3-celled, rarely i-celled, 

 With 1 ovule in each cell. Capsule obovoid or rarely globular, coriaceous or 

 hard, 2- or 3-, rarely 4 -celled, 'often angled or lobed, opening loculicidally in 

 ^as many valves as cells. Seeds usually more or less covered by an arillus ; 

 testa crustaceous or coriaceous ; embiyo curved; cotyledons plano-convex. — 

 irees or rarely tall shrubs. Leaves alternate, pinnate ; leaflets alternate or 

 opposite, with or without a terminal one. Flowers small, in small axillary or 

 terminal panicles, sometimes almost reduced to simple racemes. Petals 

 I'arely as long as the sepals. 



A large tropical genus, both in the New and the Old World, the precise limits o^ which are 

 very dilficult to fix, and are very differently viewed by different botanists. The Auatraliau 

 species are all eudemic, as far as hitherto known. 



Sepals orbicular, much imbricate. 

 Sepals glabrous or ciliate only. 



Leaflets obtuse, pale or glaucous underneath. Capsule nearly 



sessile, deeply 3-Iobed 1. (7. semir^Iauca.

 Leaflets few, entire or slightly toothed, 



i'anicles little-branched or racemes simple. Petals very short 

 and broad. Capsule woody, villous inside.

sem 



A middle-sized tree. Leaflets 2 



to 4 or rarely 6, oblong-clliptieal, or from alaiost obovate to nearly lauccolatc, 

 obtuse or rarely almost acute or mucrouate, 2 to 3 or rarely nearly 4 in. long, 

 eutiiy, narrowed into a short pctiolule, coriaceous, glabrous and somewhat 

 shining above, more or less glaucous mulerneath. Panicles either small an<l 

 axillaiy or terminal and much branched, but shorter than the leaves, glabrous 

 Of niJuutely pubescent. Pedicels short. Sepals orbicular, ciliate, other\\ise 

 glabrous, the larger inner ones about 1 line diameter. Petals shorter, with 3 

 cuneatc hairy scales as long as the petal Stamens exsertcd. Ovary glabrous, 

 3-lobcd. Capsule 4 to 5 lines diameter, glabrous, very shortly attenuate at 

 ilie base, with divaricate compressed lobes. Seeds smooth and shining,
