p. 77. A dwarf evergreen shrub, half a foot high; radical branches 
several, woody, decumbent or prostrate-ascending, rigid, glabrate 
below, shortly pubescent and leafy towards the tip. Leaves narrowly 
elliptical, obtusely pointed at the apex, attenuate at the shortly petiolate 
base, thinly coriaceous, rigid, glabrate or softly puberulous above, 
glabrescent or shortly pubescent along the veins or puberulous beneath, 
1-13 by 3-4 in. ; lateral veins about 5 pairs, not conspicuous, margins 
revolute; stipules solitary, ovate or lanceolate, undivided, persistent, 
keeled, puberulous or glabrate, }—2 in. long, about double the length 
of the petiole. Flowers 14-14 in. long (when open), terminal, solitary 
or two together, sessile, fragrant. Calyx 3-7 in. long; tube turbinate, 
shortly and closely hairy; lobes 5, narrowly oval-oblong, $—% in. long, 
foliaceous. Corolla white ; tube 1-1} in. long, shortly and appressedly 
hairy outside ; throat hairy; lobes 5-6, imbricated, oval, }-1 in. long, 
glabrous inside, puberulous outside. Anthers included, 3—} in. long, 
shortly apiculate, base obtuse. Style pubescent, equalling the corolla- 
tube; branches 2, obtuse. 
Lower Guinea. Benguela, sporadic in stony sandy thickets between Mumpulla 
and Humpata, in flower, November 1859, Welwitsch! 
23. BERTIERA, Aubl.; Benth. et Hook. f. Gen. Pl. ii. p. 77. 
Calyx-tube short, campanulate in flower, subglobose in fruit ; limb 
produced above the ovary, cup-shaped, usually broader than the 
inferior part in flower, narrower in fruit, 5-toothed (deeply 5-lobed in 
B. breviflora), persistent. Corolla tubular, much exceeding the calyx 
(campanulate and double the length of the calyx in B. breviflora) ; 
limb rather elongated (except B. breviflora), 5—4-cleft ; lobes usually 
acuminate or apiculate, dextrorsely contorted in ewstivation (as seen 
inside) or in B. breviflora sometimes imbricated. Anthers 5-4, usually 
linear, sagittate or bi-lobed at the base, basifixed, included ; filaments 
inserted usually at the hairy throat of the corolla (except B. laza), 
very short. Disk cup-shaped cushion-shaped or annular. Ovary 
2-celled ; style more or less club-shaped, glabrous; branches 2, flat- 
tened, appressed ; ovules numerous, inserted on the tumid placentas. 
Fruit indehiscent, usually globose, pisiform, coriaceous, 2-celled, 
usually marked with about 10 slender ribs from the apex downwards. 
Seeds numerous, angular.—Shrabs with opposite shortly petiolate thin 
scarcely coriaceous leaves, persistent stipules usually sheathing at the 
base, and flowers of moderate size, rarely very small, sessile or shortly 
pedicellate, in spicate thyrsoid panicled or scorpioid terminal cymes. 
A genus of several species inhabiting also the Mascarene Islands and Tropical 
America. 
Cymes spicate or thyrsoid or oblong. Corolla-tube eylin- 
drical, much exceeding the calyx. Calyx-teeth small. 
Branches of the oblong cyme obsolete or short. 
Bracteoles small, falling short of the fruit. 
Leaves more or less narrowed at the base. 
Fruit somewhat hairy. 
Leaves sub-acuminate, distinctly but shortly 
petiolate 1. B. ethiopica.
