Stem white-hispid (as are some examples of B. hoerhaavicBfolla). One-flowered 

 brandies thicker than those of B. hoerJiaavicefolia, the 2 inmost calyx-segments longer, 

 the capsule larger.

 Slender, hairy or nearly glabrate. , Leaves apparently -l-nate in distant 

 whorls, up to P)J by J in. (or in var. leptophylla, 8. ]Moore, I.e., 3 by 

 ■^^ in., exactly linear). One-flowered branches (reduced spikes) sessile, 

 axillary, solitary ; bract | in. long, oblong-obovate ; bracteoles 0. Pos- 

 ticous calyx-segment | in. long, 8-nerved ; 2 inmost segments lanceolate-

 Leaves 4 in a whorl, up to 7 by f in., lanceolate. One-flowered branches

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. cuayizensis, var. 

 lepiophylla, S. Moore. 



5. B, glumacea, S. Moore in Journ. Bot. 1880, 232. Sparingly 

 pubescent. Stem slender, flexuous. Leaves apparently in distant whorls 

 of 4, outer pair very much smaller, up to 3 by \ in., narrowed at either 

 end, sessile. One-flowered branches (reduced spikes) solitary, glabrous 

 or with the calyx puberulous ; bract J in. long, elliptic-lanceolate ;
