I do not feel much confidence in referring the plsthts cited to one species. The 

 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 

 glabrous, grey. Stipular spines short, sharply recurved. Leaf-rachis 

 J- 1 in. long with a sessile gland near the base, and occasionally a 

 minute one between the upper pinnae ; pinnae in 3-4 pairs ; leaflets in 

 8-12 pairs, oblong, obtuse, glabrate, glaucous-green, coriaceous, 2J-3 

 lines long, nearly 1 line broad. Peduncles axillary, \-\ in., the invo- 

 lucel near the base. Legume 2-valved, straight or slightly curved, 

 linear, margins parallel, compressed, obtuse or obtusely pointed, 3-3J 

 in. long |-| in. broad ; valves rather thinly coriaceous, nearly smooth 

 or very obscurely longitudinally nervose, dark brown, obsoletely pube- 

 rulous; 5-8-seeded. 



Lower Guinea. Mossamedes, Dr. Welwitsch! Between Benguella and Katom- 

 bela, Dr. Wawra. 



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. ; pinna? 2-3-jugate, leaf- 

 lets 7-15-jugate. 



24. A. hebeclada, DC. ; Benth. in Hook. Journ. Bot. 1842, 499. 

 Branches pubescent. Spines scarcely exceeding J in. in our specimens, 

 the lowest of each shoot short, slightly curved, the upper straight. 

 Pinnae 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, 

 J-li 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, f-1 in. broad, nearly \ in. in thick- 

 ness. Seeds compressed, with a long funicle, broadly elliptical or 

 roundish, \-\ in. long. 



South Central ? Baines ! Without precise locality. 

 Also south of the Tropic. Baines' plant is in fruit only. 



25. A. nubica, Benth. in Bond. Journ. Bot. 1842, 498. Shrub; 

 branches glabrescent, voung shoots at first pubescent. Stipular spines 

 straight or very slightly curved. Pinnae in 3-12 pairs ; rachis thinly 

 pubescent or glabrate with 2 or 3 minute sessile glands or eglandular ; 

 leaflets in 6-15 pairs, oblong obtuse or broadly pointed, glaucous, 2-3 

 lines long. Peduncles 1-3 from each axil, pubescent or puberulous, 

 about Jin. 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,
