7. Entada Apans.—Flowers of Adenanthera; receptacle short 
cupuliform, lined by a disk. Legume straight or bowed (in a few 
species very large), plano-compressed; margins straight or some- 
what constricted between seeds; pericarp thin submembranous or 
coriaceous, or more rarely woody; sutures thick persistent con- 
tinuous; valves lomentaceous transversely articulated, separating 
between the sutures; endocarp in separate 1-seeded segments per- 
sisting round the orbiculate thick included seed and separating from 
exocarp.—Shrubs, often high-climbing, unarmed ; leaves 2-pinnate ; 
pinne of highest row sometimes changed into spiral tendrils; leaflets 
either small numerous or larger few; stipules small setaceous; 
petiolar glands 0; flowers in spikes; spikes thin solitary or gemi- 
nate, placed at extremities of twigs, sometimes approximated to 
form a leafless racemose panicle (Zropical America, Asia, Oceania, 
and Africa).—See p. 26. 
8. Tetrapleura Bentu.— Flowers of Entada.” Legume oblong 
4.gonous, nearly straight or subfalciform, indehiscent thick; sutures 
2 and faces 2 produced to form thick angular longitudinal cruciate 
wing; endocarp thick, spuriously septate within between separate 
compressed transverse seeds.—An unarmed tree; “leaves opposite 
2-pinnate; small leaflets and pinne oo-jugate; flowers in spiciform 
cylindrical axillary racemes” (Western tropical Africa).—See p. 27. 
9. Gagnebina Necx.—Flowers of Adenanthera, but with convex 
receptacle and hypogynous perianth. Legume linear-oblong some- 
what thick compressed indehiscent; sutures with membranous 
wings; endocarp thick projecting within between seeds; locelli o, 
each containing 1 transverse ovate seed.—An unarmed tree; leaves 
2-pinnate ; small leafless and pinne o-jugate; petiolar gland broad ; 
jugal glands small setaceous; flowers in spikes; spikes cylindrical 
pedunculate, fascicled in higher axils, or panicled at extremities of 
twigs (Madagascar).—See p. 27. 
10. Prosopis L.—Flowers of Piptadenia ; staminal gland of vari- 
able form, usually deciduous, more rarely 0. Legume linear thick 
compressed or subterete, straight or falciform, hard and circinate (Cir- 
cinaria) or variously contorted, more rarely bent into a more or less 
regular and close spiral (Stromdocarpus), sometimes straight very
