ovate, suddenly narrowed into a narrow-lanceolate spinous tip which is 
rigidly recurved, adpressed to the back of the (apparently truncate)

Stem white-hispid (as are some examples of B. Loerhaaviefolia). One-flowered 
branches thicker than those of B. boerhaaviefolia, the 2 inmost calyx-segments longer, 
the capsule larger. 
3. B. cuanzensis, Welw. ex S. Moore in Journ. Bot. 1880, 230. 
Slender, hairy or nearly glabrate. Leaves apparently 4-nate in distant 
whorls, up to 34 by ¢ in. (or in var. leptophylla, 8. Moore, l.c., 3 by 
to in., exactly linear). One-flowered branches (reduced spikes) sessile, 
axillary, solitary ; bract 3 in. long, oblong-obovate; bracteoles 0, Pos- 
ticous calyx-segment # in. long, 3-nerved ; 2 inmost segments lanceolate-

eaves 4 in a whorl, up to 7 by 2in,, lanceolate. One-flowered branches

calyx-segment exceeding 1 in. in length, 2 inmost segments ? in. long. 
Corolla exceeding 1 in. in length, bright blue. 
Lower Guinea. Angola; Malange, Buchner, 16a! 
Closely allied to B. cuanzensis, as Lindau states. The leaves are much longer, 
Lindau Says narrower, but they are not nearly so narrow as in B. cwanzensis, vat. 
leptophylla, 8. Moore.
