I do not feel much confidence in referring the plants cited to one species. e 
leaves, spines, and position of the involucel agree fairly well. 
23. A. reficiens, Wawra et Peyr., Sert. Beng. 15, A low much- 
branched shrub of 3-6 ft. with white bark; extremities at length 
‘labrous, grey. Stipular spines short, sharply recurved. Leaf-rachis 
i in. long with a sessile gland near the base, and occasionally a 
minute one between the upper pinne ; pinne in 3—4 pairs ; leaflets in 
8-12 pairs, oblong, obtuse, glabrate, glaucous-green, coriaceous, 23-3 
lines long, nearly 1 line broad. Peduncles axillary, }—-1in., the invo- 
lucel near the base. Legume 2-valved, straight or slightly curved, 
linear, margins parallel, compressed, obtuse or obtusely pointed, 3-33 
in. long }—3 in. ere valves rather thinly coriaceous, nearly smooth 
or very obscurely longitudinally nervose, dark brown, obsoletely pube- 
tulous; 5—8-seeded. 
Lower Guinea. Mossamedes, Dr. Welwitsch! Between Benguella and Katom- 
bela, Dr. Wawra. ee 
Described from Dr. Welwitsch’s specimens, and identified by above-cited description 
only. Dr. Wawra’s plant is described as a shrub of 8-12 ft.; pinnee 2-3-jugate, leaf 
lets 7-15-jugate. 
24. A. hebeclada, DC. ; Benth. in Hook. Journ. Bot. 1842, 499. 
Branches pubescent. Spines scarcely exceeding }in. in our specimens, 
the lowest of each shoot short, slightly curved, the upper straight. 
Pinne in 2-7 pairs; rachis pilose-pubescent, interpinnal glands very 
minute ; leaflets linear-oblong, broadly acute or obtuse, thinly ciliolate 
or glabrous, in 8-15 pairs. Peduncles solitary or 2 or 3 from each axil, 
4—1j in. long; bracts minute at the base (or occasionally near the 
middle ?) of the peduncle. Flowers capitate. (Calyx denticulate, pilose- 
margined, half as long as petals in the Cape form.) Legume straight, 
thick, 2-valved, with a continuous cavity, oblong or linear-oblong, 
obtuse or apiculate, compressed, valves continuous, woody, longitudi- 
nally faintly ridged, 3-6 in. long, 3-1 in. broad, nearly }in. in thick- 
ness. Seeds compressed, with a long funicle, broadly elliptical or 
roundish, 4—} in. long. 
South Central? Baines! Without precise locality. 
Also south of the Tropic. Baines’ plant is in fruit only. 
25. A. nubica, Benth. in Lond. Journ. Bot. 1842, 498. Shrub ; 
branches glabrescent, young shoots at first pubescent. Stipular spines 
straight or very sibily curved, Pinne in 3-12 pairs; rachis thinly 
pubescent or glabrate with 2 or 3 minute sessile glands or eglandular ; 
leatlets in 6-15 pairs, oblong obtuse or broadly pointed, glaucous, 2-3 
lines long. Peduncles 1-3 from each axil, pubescent or puberulous, 
about din. long, bearing the involucel usually below the middle. 
Calyx-teeth short, rounded. Petals connate nearly throughout, scarcely 
twice as long as the calyx. Legume linear-oblong, straight or nearly 
so, compressed, narrowed at each end, margins narrowly compressed 
or subalate, valves continuous, slightly convex, firmly coriaceous,
