(usually 2-) ovulate ; style slender ; stigma small capitate. Legume 

 lanceolate piano-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 ; liilum 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 {Tropical and 

 subtropical America). See p. 7S. 



8. Poinciana L. — Flowers subregular (of Casalpinia) ; sepals 5, 

 subequal thick valvate. Petals subequal (or highest innermost 

 unlike the rest), much imbricated. Stamens 10 (of Casalpinia), 

 exserted. Germen sessile or shortly stipitate, central or somewhat 

 excentric, cc-ovulate ; style thin, short or elongated ; apex some- 

 times clavate ; stigma small terminal, truncate or minutely ciliate. 

 Legume elongated piano-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 ; 

 flowers handsome, in racemes or corymbs on extremities of twigs ; 

 bracts small caducous ; bractlets {East Indies, hot regions and 

 islands of Eastern Africa). See p. 80. 



9. Colvillea Boj. — 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 ; cal} T x finally 

 separating by circumscission from base. Corolla of Poinciana ; highest 

 petal innermost and broader. Stamens 10 (of Ctesalpinia). Germen 

 subcentral free oo-ovulate ; style slender; apex obtuse stigma- 

 tiferous. " Legume elongated straight thick tui'gid 2-valved. 

 Seeds transverse oblong ; hilum small." — An unarmed tree ; leaves 

 2-pinnate go foliolate ; stipules minute caducous; flowers in thick 

 branched racemes; rachis thickened; bracts membranous coloured 

 caducous ; bractlets {Madagascar). See p. 80.
