1. B. Trixago, Linn. Sp. Pl.ed.i.602. Annual, somewhat hispid, 
6-18 in. high. Stems simple or slightly branched in the inflorescence. 
Leaves sessile, thick but not rigid, spreading, narrow-lanceolate, 1-24 
in. long, distantly and coarsely toothed or shallowly pinnatitid ; teeth 
and tip obtuse ; primary veins 4 or 5 on each side, terminating in the 
sinuses between the teeth. Inflorescence terminal, usually unbranched, 
very dense, usually 2-3 but ranging from 1-5 in. long; floral leaves or 
bracts nearly as long as the flowers. Flowers sessile, yellow, 6-8 lin. 
across, Calyx 3-4 lin. long, densely tomentose, thick ; lobes slightly 
unequal, very obtuse or rounded, shorter than the tube. Corolla 6-7 
lin. long; tube slightly exceeding the calyx; upper lip galeate, enclosing 
the slightly bearded anthers; lower lip broad, unequally three-lobed, 
middle lobe smallest, spreading; palate longitudinally bigibbous. 
Filaments glabrous, dilated downwards, Ovary hirsute; style puberu- 
lous. Seeds very small, reniform, longitudinally ribbed.—Sibth. &

Also in the Mediterranean region and South Africa and colonised in several other 
Countries. We think it probable that it wes originally introduced into South Africa, 
inasmuch as we have seen no specimens from the country between that and 
Abyssinia. 
2. B. Mannii, Hemsl. Perennial, very rigidly hispid, 2-3 ft. 
high. Stems simple or branches few, spreading, at length woody ; 
internodes nearly as long as the leaves. Leaves shortly but distinctly 
stalked, thick, rigid, spreading, narrowly lanceolate, 3-1} in. long, 
floral gradually smaller, obtuse, base rounded ; venation strong, with. 
about four primary veins on each side; margin broadly crenate.
