River, 1000 ft., Dréye ! Natal; without precise locality, Gerrard, 1973! 
This species may turn out to be only a large form of B. Gueinzii, but not 
a variety of B. obtusa.

leaves 18 by 3-2 in., elliptic-oblong, entire, hairy on both faces ; 
petioles 0O-, in.; racemes up to 6-flowered (mostly 3—1-flowered), 
axillary, condensed ; outermost bracts foliaceous, lanceolate, not spinous; 
other bracts $—1} in. long, broadly elliptic, acute, with many innocuous 
marginal teeth; corolla blue or white, 14 in. in total length; tube 
cylindric, in the upper half funnel-shaped.

13. B. jasminiflora (C. B. Clarke); branches 5 in. long, hairy, 
spreading from a woody root; leaves scarcely 1 by 1 in., oblong, 
entire, mucronate, sparsely hispid with simple hairs, subsessile ; 
flowers solitary; outer bracts 4 in. long, lanceolate, rather rigid, 
viscous, with.a few bristles on the margins; posticous sepal 2 in. 
long, elliptic or ovate, spine-tipped, rather rigid, with bristles on the 
margin ; corolla about 1 in. long (judging by the style), lake-coloured 
(Burchell). 
Coast Reoion: Uitenhage or Humansdorp Div. ; between Galgebosch and 
Melk River, Burchell, 4759! 
Burchell notes that the flowers were shaped as those of jasmine, with equal 
spreadivg corolla-lobes, 
14. B. affinis (C. B. Clarke) ; whole plant stellate-hairy ; branches 
6-8 in. long, slender; leaves 1-1 in. in diam., ovate or orbicular,

petiole up to 3-3 in. long; flowers axillary, solitary ; outermost 
bracts }-} in. long, linear, scarcely spinescent ; posticous sepa] } in. 
long, ovate, nervose, with many innocuous teeth on the margins ; 
corolla (judging by the style) not less than 4 in, long. 
KALAHARI REGION: Transvaal; Marico District, Holuds 
_ This plant is closely allied to B. spinulosa, Klotzsch, from Mozambique, and to 
its very close allies in Mozambique,

innovations neither silky nor woolly ; trailing branches 1-2 ft. long, 
from the crown of a woody rootstock ; leaves (in type examples) 3-1

petiole O-} in. long (in other examples broader leaves occur); heads 
axillary, remote, in flower 13 by 1 in., in fruit 2 in. and upwards in 
length, and very thick; calyx-segments (and bracts similar to 
them) very densely imbricated in 4 ranks, the 2 ranks on one 
side empty (bracts), the 2 ranks on the other side being sepals ;
