1. PELTOPHORUM, Vogel; Benth. et Hook. f. Gen. Plant. i. 565. 
Sepals 5, united at the base into a short obconical tube, lobes imbri- 
cate, nearly equal. Petals obovate or orbicular, narrowed below, 
undulate. Stamens 10, free, filaments densely pilose within at the 
base; anthers uniform, linear-oblong. Ovary sessile or very shortly 
pedicellate, with 2 or more ovules: style elongate; stigma broadly 
peltate. Legume flat, oblong or oval, indehiscent, valves consolidated 
around the median cavity forming a wing on each side, usually longi- 
tudinally striate, 1-few-seeded. Seeds oblong, compressed, albuminous 
(in the African species); cotyledons flat, radicle ovoid, straight, partly 
exserted.—Trees, destitute of prickles. Leaves twice pinnate ; leaflets 
numerous. Flowers yellow in erect single or panicled bracteate 
racemes. 
A small genus, represented in both hemispheres. The following is the only African 
species. 
1. P. africanum, Sond. in Linnea, xxiii. 85. A tree of 20-80 ft. 
(in Angola, Dr. Welwitsch); leafy extremities rusty-pubescent or tomen- 
tose. Pinne usually in 5-10 pairs, opposite or subopposite ; leaflets 1n 
10-20 pairs on the upper or median pinne, oblong, mucronulate, thinly 
pubescent or glabrate above, paler with adpressed pubescence beneath, 
base slightly oblique, sessile, 2-3 lines long. Racemes erect, slightly 
overtopping the leaves, 4—7 in. long, shortly tomentose-pubescent. bracts 
subulate, shorter than or nearly equalling the pedicels, sometimes cadu- 
cous. Calyx-tube short, obconical, glabrous within, as are the reflexed 
ovate-oblong obtuse lobes. Petals obovate or rotundate, much nar- 
rowed, and sometimes pilose on the median line below. Filaments 
densely pilose at the base inside. Ovary subsessile, adpressed-hirsute 5 
style recurved, glabrous above ; ovules about 3. Fruit much compressed, 
coriaceous, oblong, tapering to each end, puberulous or glabrate, with 
longitudinal anastomosing strie, excepting along the winglike margin ; 
23-3 in. long, 2-1 in. broad, 1—2-seeded. 
Lower Guinea. Mossamedes ard Huilla, Angola, Dr. Welwitsch ! 
South Central. Near Lake Ngami, J. M‘Cabe! 
Occurs also in the Macalisberg, south of the Tropic. 
2. MEZONEURUM, Desf.; Benth. et Hook. f. Gen. Plant. i. 565. 
Calyx-tube short, very oblique, segments 5, broadly imbricate, 
deciduous, the anterior segment larger, concave or hooded, exterior and 
enclosing the rest in bud. Petals 5, rather unequal. Stamens 10, 
free ; filaments glabrous or pilose below ; anthers uniform, elliptical or 
oblong, dehiscing longitudinally, connective slightly thickened behind. 
Ovary sessile or shortly stipitate with 2 or more ovules; style subulate ; 
stigma terminal, truncate or dilated-infundibuliform. Legume inde- 
hiscent or nearly so, more or less coriaceous, much compressed, ventral 
suture only longitudinally winged or dilated. Seeds 1-o , compressed,
