296 XLVII. § CHESALPINIEH (OLIVER). ( Berlinia. 
The nervation of the leaflets is curious: the lower half of each has 2 or 2 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 8—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 2lines or less. Involucral bracteoles oblanceolate 
concave $-2in. long. Calyx-tube }-}in., narrow glabrous, segments 
linear or oval-oblong 3—$in. long. Petals nearly equal in length, 
pee obcordate or obovate-cuneate bifid narrowed below, 6-7 lines 
ong, 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, 2 ft. long. 
Lower Guinea. Province of Pungo Andongo, Angola, Dr. Welwitsch! 
Var. subcordata (Welw.) Leaflets broader, elliptic-oblong, rounded or emarginate 
above, broadly rounded or subcordate at base. Pungo Andongo, Dr. Welwitsch ! 
6. B. stipulacea, Benth. in Linn. Trans. xxv. 310. Tree of 20-80 
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 ; 2-8 in. long, 1-2 in. 
broad ; petiolules stout 1-2lines. Stipules present at flowering, lan- 
ceolate acute erect rigid, connate below by their outer margins, 14—2 in. 
long. Flowers in terminal panicled corymbose racemes. ieee deeply 
concave }—} in. long, early caducous. Pedicels 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, 24-4 lines long. Posterior petal 2-24 in., lamina 1-1} in. broad, 
deeply bifid, abruptly cuneately narrowed into the long narrow gla- 
brous claw unappendaged at base; remaining petals 44 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 - - - 
Upper Guinea. River Muni, Mann! 
Probably generically distinct.
