LEGUMINOS24-CHSALPINIEZ. 165 
(usually 2-) ovulate; style slender; stigma small capitate. Legume 
lanceolate plano-compressed membranous leaf-like, indehiscent at 
sutures but bursting longitudinally down middle of valves to form 
2 unequal navicular pseudovalves. Seed 1 (more rarely 2), trans- 
versely oblong; hilum ventral depressed; embryo exalbuminous 
fleshy ; cotyledons with 2 widely divaricating lobes, narrowed at 
base; radicle very short straight, retracted between lobes of coty- 
ledons.—A. glabrous tree; leaves pinnate or 2-pinnate; leaflets 
paucijugate, unevenly obovate; stipules sometimes minute deci- 
duous, sometimes spinescent persistent; flowers in short axillary, 
solitary or fascicled racemes ; bracts minute caducous (Zropical and 
subtropical America). See p. 78. 
8. Poinciana L.—Flowers subregular (of Cesalpinia) ; sepals 4, 
subequal thick valvate. Petals subequal (or highest innermost 
unlike the rest), much imbricated. Stamens 10 (of Cesalpinia), 
exserted. Germen sessile or shortly stipitate, central or somewhat 
excentric, o-ovulate; style thin, short or elongated; apex some- 
times clavate; stigma small terminal, truncate or minutely ciliate. 
Legume elongated plano-compressed, sometimes very long, hard 
veined, replete between seeds, 2-valved. Seeds oblong; testa hard ; 
embryo albuminous ; cotyledons rather thick; radicle straight short 
exserted.—Unarmed trees; leaves 2-pinnate; stipules minute or 0; 
flowers handsome, in racemes or corymbs on extremities of twigs; 
bracts small caducous; bractlets 0 (Hust Indies, hot regions and — 
islands of Eastern Africa). See p. 80. 
9. Colvillea Bos.— Flowers of Poinciana; calyx ventricose ; 
sepals coriaceous thick induplicate-valvate, connate at apex into a 
5- or more rarely 4-toothed sac, highest tooth broader ; calyx finally 
separating by circumscission from base. Corolla of Poinciana ; highest 
petal innermost and broader. Stamens 10 (of Cesalpimia). Germen 
subcentral free oo-ovulate; style slender; apex obtuse stigma- 
tiferous. “Legume elongated straight thick turgid 2-valved. 
Seeds transverse oblong; hilum small.’—An unarmed tree; leaves 
2-pinnate oo-foliolate; stipules minute caducous; flowers in thick 
branched racemes; rachis thickened; bracts membranous coloured 
caducous ; bractlets 0 (Madagascar). See p. 80.
