The Tropical African examples agree exactly with the type-plant of 2B, setosa, 
Nees; but this type is marked by T. Anderson, “ B. satureiifolia, var. linearifolia, 
T. Anders,” 
10. B. fruticulosa, C. B. Clarke. A nearly glabrate, small, dense 
shrub; branches woody. Leaves 4 by } in., oblong, hard, whitish. 
Bracteoles 4 by 3, in. long, lanceolate, mucronate, beautifully veined, 
minutely hairy upwards. Two inmost calyx-segments like the 
bracteoles ; otherwise as B. molluginifolia.

long, linear-lanceolate. Corolla 1 in. long, blue (Scott-Elliot). Anticous 
filaments very broad.

This may prove only a luxuriant mountain form of B. molluginifolia. It differs 
mainly by the much larger corolla. 
12. B. pratensis, S. Moore in Journ. Bot. 1877, 294. Shrub 
6-15 ft. high, hairy, afterwards often glabrate. Leaves apparently in 
whorls of 4, up to 24 by 42 in., somewhat leathery, narrowed at both 
ends, subsessile. One-flowered branches (reduced spikes) in loose 
eads ; lowest sterile bracts (and floral leaves) lanceolate, often few- 
spned on the margin; flower-bract proper broadly-obovate, suddenly 
acuminate, mucronate (without spinous cilia at the tip); bracteoles 
% in, long, lanceolate, acuminate, mucronate, 1-nerved, subentire, 1.€. 
Without spines near the tip. Posticous calyx-segment } in. long and 
Upwards, lanceolate, mucronate, entire, minutely and closely hairy with- 
out; 2 inmost calyx-segments about half as long, lanceolate. Corolla 
exceeding 1 in. in length, blue.—Lindau in Engl. Pf. Ost-Afr. C. 369.

The bracteoles are said by S. Moore to be 2-3-nerved. The discrepancy between 
the deser iptions of bracteoles bere given and those of preceding authors is mainly one 
of terms, the word « bracteole ” being restricted here to the 2 lateral “ prophylla. 
1. B. Welwitschii, §. Moore in Journ. Bot. 1880, 231. Sterile 
cts spinous on the margins; flower-bract ovate, acuminate, spinous

8. Moore says that this species is very close to B. pratensis, and it seems to differ 
Ad little except in the more spinous sterile bracts and in the markedly Mellel 
OWer-bract. ‘The young branches are more scabrous, the leaves 2 by & in. parallel 
‘ded, the flowers rather larger ; but these differences are small.
