prominent bifid callus, channelled in front, enclosing the posterior 
staminode, the filament of which is abruptly dilated in the middle. Two 
stamens perfect with straight filaments, incurved at the tip, and incurved 
oblong anthers dehiscing on the inner face. Shorter stamens variously 
deformed or effete. Ovary biovulate, narrowed into a slender style 
curved above.

2. B. cissoides, Welw. mss. A climbing rusty-tomentose or pubes- 
cent shrub; extremities sulcate or obtusely angular, the ridges occa- 
sionally at length glabrate. Leaves firmly membranous, suborbicular 
or transversely dilated, 3-7 in. broad, basal sinus usually narrow (seg- 
ments sometimes overlap), extending about one-third the length of leaf, 
apical sinus very broad and shallow or apex entire; leaflets broadly 
rounded above and below each with 5-7 strong divaricately forking 
nervures beneath, glabrous sometimes glaucous above, tomentose or 
tomentose-pilose on the under surface and petioles which vary from 
2-6 in. in length. Racemes pedunculate, laxly 6—18-flowered, clothed 
with ferruginous tomentum, with the peduncle 4~1 ft. long. Bracts 
narrow, }—+ in. long, usually present at flowering. Pedicels ascending, 
or at length patent, sometimes slightly recurved towards the apex, 1—2 
in. long. Buds ellipsoidal, rather obtuse, ? in. long. Calyx-tube cam- 
anulate, about 4—} as long as the linear segments, which are more or 
fons distinctly dorsally carinate towards the apex. Anterior petals 
yellow or orange, pilose externally, rotundate, clawed, 2—4 times longer 
than the calyx; posterior petal with a prominent erect narrow bifid 
callus, nearly 2 lines in length. Fertile stamens usually 2. Ovules 2. 
Legume flat at right angles to the gynophore of 4 in. in length, ob- 
liquely obovate or rotundate, rounded or apiculate at the apex, 2-valved, 
valves hard, smooth, or faintly ridged transversely, the ventral suture 
but inconspicuously thickened; valves consolidated towards the apex 
and dorsal suture, 34—4 in. long, 24 in. broad. Seeds not examined.

3. B. Welwitschii, Oliv. A procumbent or scandent shrub, with 
the general characters of B. cissoides, and like it clothed on the stem, 
| srewers and inflorescence with a tawny or ferruginous tomentum. 
eaves usually with a broader basal sinus, and the midrib sometimes 
excurrent at the apex in a fine apiculus; 4—6 in. broad; petioles 14-6 
in. Racemes as in B. cissoides. Bracts linear-subulate, 3 in. long more 
or less. Pedicels 1-2 in. Buds lanceolate or ovoid-lanceolate, 1 in. 
long on expansion. Calyx-lobes long and narrow-linear, the two posterior 
segments sometimes late cohering, 4-6 times as long as the tube, all 
more or less dorsally crested above. Anterior larger petals obovate or
