 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 Thorn, 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-, T V~i 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. Oldenlandice, DC. Prod. iv. 54;

V. tomentosa, A. DC. Prod. I.e. 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 6pecies 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 \ 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! Y&r. verlaso' flora (Welw.mss.) 

 flowers subsessile ; petals orbicular. Mossamedes, Dr. Wdwitsch ! 



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.

Calyx 5-partite, lobes coriaceous, imbricate, much shorter than 

 petals. Petals elliptical, coriaceous, spreading, contorted-imbricate in 

 bud. Stamens 5, subhypogynous ; filaments slightly dilated below, 

 alternating with the toothed lobes of the disk. Ovary superior, taper-
