prominent bifid callus, channelled in front, enclosing- the posterior

2. B. cissoides, Welw. mss. A climbing- rusty-tomentose or pubes- 

 cent shrub ; extremities sulcate or obtusely ang-ular, the ridg-es 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, g-labrous sometimes g'laucous 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 J— 1 ft. long-. Bracts 

 narrow, \— Jin. long-, usually present at flowering-. Pedicels ascending-, 

 or at length patent, sometimes slig-htly recurved towards the apex, 1—2 

 in. long. Buds ellipsoidal, rather obtuse, § in. long. Calyx-tube cam- 

 panulate, about J— J as long as the linear segments, which are more or 

 less 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 J 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, 3|— 4 in. long, 2J 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, 

 petioles and inflorescence with a tawny or ferruginous tomentum. 

 Leaves usually with a broader basal sinus, and the midrib sometimes 

 excurrent at the apex in a fine apiculus ; 4-6 in. broad ; petioles 1 J-6 

 in. Racemes as in B. cissoides. Bracts linear-subulate, <| 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
