1-2 lines long. Calyx-lobes erect, a little broader than in W. rudis, Capsule 
hairy, the valyes twice shorter than the calyx lobes, 
22. W. prostrata (A. DC. ! Prodr. p. 431) ; branches divergent from 
the base, simple, prostrate, terete, nearly glabrous; leaves scattered, 
alternate and opposite, thickish, linear, incurved, channelled above, 
acute, denticulated, teeth terminated by a minute bifid mucro, panicle 
3-5 flowered ; pedicels as long or longer than the bractea or the calyx ;

fundibuliform-campanulate, 5-lobed at the apex ; capsule hemispher'- 
cal, glabrous, W.? prostrata, EH. Mey. 
- Has. Between Zilverfontein, Kooperbergen and Kaus, Namaqualand, 2—3000 
ft. Drege, Sept.-Oct. (Herb. Hook, Sd.) 
Annual. Root 3-4 inches long, white, simple. Stems or branches scarcely longer 
than the root. Leaves sessile, 3-4 lines long, 1 line wide, spreading-recurved, 
rather fleshy, on each side with 6-8 minute bispinous teeth, glabrous or subpilose 
near the base. Pedicels 1-2 lines long, minutely hairy. Calyx 1 line long. Corolla 
nearly half an inch long, the lobes obtuse or apiculate. Stamens and trifid style 
shorter than the corolla. Capsule crowned by the spreading recurved calyx-lobes. 
23. W. ingrata (A. DC.! Prodr. p. 432); branches ascendent from 
the base, glabrous, simple, ending in a 7-12-flowered panicle; leaves 
scattered, alternate and opposite, thickish, linear, channelled above, 
acute, denticulated; teeth terminated by a minute, bifid mucro ; pedi- 
cels as long or shorter than the bractea or the calyx ; tube of calyx 
hemispherical, hairy, nearly as long as the lanceolate denticulate, ciliate 
lobes ; corolla 4—5 times longer than the calyx, tubulose, 5-lobed at the 
apex ; capsule hemispherical, hairy. W. divaricata, b., L. Mey. in herb. 
Drege (ex DC.) non litt. a. 
Has. Sandy plains near the mouth of the Gariep, Drege. Oct. (Herb. Sd.) 
Scarcely to be separated from the preceding, with which it has the long, white 
roots, simple stems or branches and leaves. The difference lies only in the more 
roundish calyx, with spreading hairs, and the narrow, not campanulate corolla. 
Leaves 4-6 lines long, subpilose near the base. Pedicels glabrous. Capsule 1 line 
long, equalling the recurved-spreading calyx-lobes and the valves of capsule. 
24. W. oocarpa (Sond.); stems erect, subpilose ; branches filiform, 
paniculated; leaves alternate, erect, linear, narrow, entire or indis- 
tinctly denticulate, glabrous or subpilose ; panicle dichotomous; pedi- 
cels erect-spreading, capillagy, 3-4 times longer than the bractea ; 
calyx tube oval, glabrous ; lobes subulate, twice shorter than the tube ; 
corolla tubulose, 5-lobed at the apex, 2-3 times longer than the calyx ; 
capsule ovoid, terete. 
Has. Sandhills on the Zwartkopsriver, Zey. 3140. Octob. (Herb. Sd.) 
A slender annual, 4-6 inches high. Root longish, simple. Stem solitary, or 2-4, 
often flexuous, dichotomously branched. Leaves 3-4 lines long, 4 line wide, 
acute, sessile ; the lowermost opposite. Pedicels 4-6 lines long, glabrous. Flowers 
small, calyx in flower 1 line, corolla about 2 lines long. Capsule 2 lines long, 3- 
rarely 4-valved ; valves equaling the short, erect calyx lybes. 
25. W. exilis (A. DC.! Monog. p. 151, t. xvi.) ; stem much-branched, 
subpilose at the base ; branches glabrous, filiform ; leaves scattered,
