RUTACEÆ. 503 
angular base of germen recurved, subfree or cohering at middle 
among themselves ; ovules solitary, finally ascending. Drupes 1—5, 
scarcely fleshy ; putamen crustaceous or coriaceous ; seeds formed 
like cell, copiously filled with albumen; embryo straight.—Bitter 
trees; leaves alternate imparipinnate; folioles entire or glandular- 
dentate ; the inferior sometimes stipuliform; flowers’ in axillary 
ramified cymiferous racemes’ (Trop. and Hast. Asia’). 
96. Picrolemma Hook. r.'—Flowers diæcious; male usually 
4-merous ; calyx cupular, imbricated, and petals longer, alternate, 
imbricated, punctuate, deciduous. Stamens 4, oppositipetalous, 
inserted round minute rudimentary gyneceum; glands 4, small 
alternate ; filaments free, more or less corrugated in bud; anthers 
2-rimose. Female flowers usually 5-merous; stamens 5, sterile 
rudimentary, inserted below base of 5 carpels ; germens free ; ovules 
in each solitary, descending; style short, thick, capitate, stigma- 
tiferous at apex. Drupes’ (solitary by abortion); flesh scanty ; 
putamen thin, crustaceous; linear hilum of seeds and embryo of 
Quassia.—Small simple glabrous trees; bark very bitter; leaves 
alternate imparipinnate; folioles multijugate, petiolulate, entire ; 
flowers* in slender irregularly ramified cymiferous racemes shorter 
than leaf (Zrop. South-East. America). 
97. Brucea Mirr'—Flowers polygamous (nearly of Picrena), 
4-merous, sepals short, imbricated. Petals longer, imbricated. 
Stamens 4, alternipetalous (effete in female flower), inserted exter- 
nally below disk between the 4 lobes; filaments free, naked ; anthers 
introrse, 2-rimose. Carpels 4, oppositipetalous (rudimentary or 0 
in male flower); germens free ; styles free, usually thick, recurved, 
inwardly at middle only cohering among themselves, otherwise free, 
inwardly stigmatiferous patent at apex ; ovule in germens solitary,
