384 XLIX. SAXIFRAGACEH (OLIVER). [ Vahlia. 
Wile Land. Sennaar and Kordofan, Kotschy! Khartoum, Consul Petherick! 
Also in Egypt and eastward in Persia and India. The Indian form seems to have 
generally narrower leaves, varying to lanceolate or oval-oblong. 
2. V. oldenlandioides, Roxb. ; Hook. f. et Thom. in Journ. Linn. 
Soc. ii. 74. An erect or diffuse branching annual clothed more or less 
with crisped pubescence or glandular-pubescent above, 2 or 3 in. to 1 ft. 
Leaves linear or linear-oval acute, usually from }—2 in. long, y;—}.in. 
broad. Peduncles 2-flowered from the upper axils, erect, several times 
longer than the flowers or in dwarfed forms scarcely longer than the 
calyx-tube; pedicels very short, rarely exceeding the calyx-tube. 
Calyx-lobes ovate-lanceolate acute, equalling the tube at flowering, at 
length often shorter. Petals obovate-oblong or -rotundate. Filaments 
not perceptibly appendaged, twice or more than twice as long as the 
anther. Styles short, divaricate——V. Oldenlandie, DC. Prod. iv. 54;

Also in India. 
V. tomentosa, A. DC. Prod. 1l.c. I do not know from authentic specimens. It is 
from Cayor in Senegambia. The description is too brief, and affords no character by 
which to distinguish it from species here described. 
3. V. capensis, Thunb.; DC. Prod. iv. 53. Erect or diffuse herb 
from a few inches to 1 ft. or more in height, shortly crisped-pubescent or 
glabrate, occasionally woody at the base and probably then biennial or 
perennial. Leaves linear acute, }—1 in. long. Flowers geminate from 
all the upper axils, either subsessile or on erect slender peduncles 
nearly 4 in. long; pedicels usually very short. Calyx-teeth lanceolate 
or linear-lanceolate acute or acuminate, exceeding the campanulate 
tube. Petals varying from orbicular subsessile to oblanceolate acute, 
usually nearly equalling the calyx. Anthers oblong or oval, equalling 
or exceeding the filaments. Styles slender, equalling or exceeding the 
calyx-lobes. 
Lower Guinea. Huilla, Angola, Dr. Welwitsch! Var. verbasciflora (Welw. mss.) 
flowers subsessile ; petals orbicular. Mossamedes, Dr. Welwitsch ! 
Also at the Cape. Dr. Welwitsch’s two forms I should certainly have regarded as 
specifically distinct from each other, were it not that the Cape specimens in the Kew 
Herbarium lead me to suspect they may be varieties of one variable type. If it prove 
otherwise, the name verbasciflora proposed by Dr. Welwitsch for the broad-petalled 
sessile-flowered form may be adopted. 
3. BREXIA, Thouars; Benth. et Hook. f. Gen. Plant. i. 645. 
Calyx 5-partite, lobes coriaceous, imbricate, much shorter than 
a Petals elliptical, coriaceous, spreading, contorted-imbricate in 
ud. Stamens 5, subhypogynous; filaments slightly dilated below, 
altérnating with the toothed lobes of the disk. Ovary superior, taper-
