The nervation of the leaflets is curious : the lower half of each has 2 or 3 obliquely 

 ascending nervures from the base, while the upper half is penniveined throughout. 

 The description of the ripe legume is from Mr. Bentham. 



5. B. angolensis, Welwitsch; Benth. in Linn. Trans, xxv. 310. Tree 

 of moderate size, glabrate excepting the inflorescence and unfolding 

 leaves which are finely puberulous at first. Leaflets 3-4-jugate oval 

 or oval-oblong, the broader obtuse or retuse, narrower acuminate, thinly 

 coriaceous, prominently penniveined beneath, 4-6 in. long, or on sterile 

 branches occasionally 1 ft. or more ; petiolules short rigid with the 

 rachis sometimes permanently puberulous. Flowers small in short 

 paniculate or corymbose silky-tomentose tawny or ferruginous racemes, 

 much overtopped by the uppermost leaves. Bracts very early cadu- 

 cous. Pedicels 2 lines or less. Involucral bracteoles oblanceolate 

 concave J-| in. long. Calyx-tube \- J in., narrow glabrous, segments 

 linear or oval-oblong J-J in. long. Petals nearly equal in length, 

 posterior obcordate or obovate-cuneate bifid narrowed below, 6-7 lines 

 long, remainder subsessile, obliquely oval-oblong, plane or undulate. 

 Perfect stamens 10, distinct, filaments exserted, glabrous, or pilose 

 below. Ovary densely villous on a short stipes. Ovules 5-6, occa- 

 sionally fewer. Legume flat, broadly oblong or slightly narrowed 

 below, thickly coriaceous, obliquely rugose, f ft. long.

Var. subcordata (Welw.) Leaflets broader, elliptic-oblong, rounded or emarginate 

 above, broadly rounded or subcordate at base. Puogo Andongo, Dr. Welwitsch I 



6. B. stipulacea, Benth. in Linn. Trans, xxv. 310. Tree of 20-30 

 ft., excepting the darkly ferrugineo-puberulous inflorescence glabrous. 

 Leaves 4-5-jugate, rachis terete ; leaflets coriaceous, oval-oblong or 

 narrowly oblong, terminating in a short hard apiculus, midrib promi- 

 nent and reticulation subprominent beneath the lateral nervures con- 

 nected by a broadly-arching intramarginal nerve j 2-8 in. long, 1-2 in. 

 broad ; petiolules stout 1-2 lines. Stipules present at flowering, lan- 

 ceolate acute erect rigid, connate below by their outer margins, 1 J-2 in. 

 long. Flowers in terminal panicled corymbose racemes. Bracts deeply 

 concave J-J in. long, early caducous. Pedicels f in. Involucral brac- 

 teoles coriaceous obovate-oblong obtuse 1-1 \ in. long. Calyx very short 

 glabrous, tube 1-1 \ lines, segments linear acute, slightly dilated at 

 base, 2^-4 lines long. Posterior petal 2-2Jin., lamina 1—1 \ in. broad, 

 deeply bifid, abruptly cuneately narrowed into the long narrow gla- 

 brous claw unappendaged at base ; remaining petals J— \ in. long, 

 subequal, linear acuminate. Perfect stamens .5, free from the base, 

 filaments filiform, exserted; staminodia alternate with the stamens, 

 subulate shorter than the petals or 0. Ovary densely pilose, subsessile; 

 style elongate, stigma capitate. Ovules 7, more or less. Legume . . .
