mities of branches; bracts and bractlets subsquamous, tapering at 
margin, coloured imbricated, very caducous (Western tropical Africa). 
See p. 104. 
39. Eperua Avst.—Flowers of Berlinia; sepals 4, connate to a 
variable height, imbricated ; petal 1, sessile, very broad. Stamens 10, 
fertile, free or slightly connate at base (Parivoa). Germen stipitate, 
inserted posteriorly on margin of receptacle, o-ovulate; style 
slender, involute in zestivation; apex minute capitate stigmatiferous. 
Legume broadly oblong or elongated, usually oblique, plano-com- 
pressed, coriaceous or woody, 2-valved ; seeds few, ovate or elongated, 
compressed ; embryo exalbuminous fleshy ; radicle short included.— 
Unarmed trees, lofty or weak, sarmentose; leaves paripinnate or 
subparipinnate; leaflets few, coriaceous; stipules minute or leaf- 
like, deciduous; flowers handsome, in terminal, simple pendulous 
or branched, sometimes very long racemes; bracts and bractlets 
caducous (Tropical America). See p. 105. 
40. Afzelia Sm.—Flowers of Berlinia; sepals 4, imbricated ; 
petals, highest unguiculate, broadly orbiculate or reniform; 4 an- 
terior rudimentary or 0. Stamens 9, anterior (none superposed to 
standard) free or monadelphous (Pahudia) to a variable height; 3-7 
fertile, unequal; remainder antherless or with rudimentary anthers, 
more rarely entirely absent. Gynzceum of Berlinia. Legume stipi- 
tate, obliquely oblong, compressed, thick and coriaceous or woody ; 
transversely septate or pulpy between seeds. Seeds transverse, 
oblong or orbiculate, either bare (Jvésia) or furnished with a thick 
fleshy unevenly-cupuliform aril (Hwafzelia); embryo exalbuminous 
fleshy.— Unarmed trees; leaves pari- or subimparipinnate ; leaflets 
paucijugate coriaceous; flowers in compound branched terminal 
racemes; bracts small deciduous; bractlets 2, lateral ovate sub- 
persistent, shorter than bud (Zropical Africa, Asia, and Oceania). 
See p. 106. 
4]. Didelotia H. By.—Flowers small (of Berlinia); receptacle 
short, lined by a disk; sepals and petals very short, reduced to small 
unequal or rudimentary scales. Stamens 10, either all-fertile (Brachy- 
stegia), or 5 oppositipetalous antherless short, sometimes very short, 
more rarely entirely wanting. Germen stipitate, more or less
