 dwarf herb, only a few inches high ; branches procnmbent, naked at the 

 base, with rosettes of small leaves at the ends, from the centre of 

 which spring the almost sessile flowers. Leaves oblong-spathulate 

 obtuse or acute entire or more or less conspicuously dentate-crenate, 

 3-6 lines long, sparsely pilose and ciliate when young. Flowers very 

 small, scarcely 2 lines long, apparently solitary at the ends of the 

 branches and almost concealed by the leaves. Calyx- tube obconical, 

 naked, lobes lanceolate acute entire glabrous. Corolla oblong-cara- 

 panulate about twice as long as the calyx-lobes. Capsule globose 

 glabrous 3-celled. — Description of the flower and capsule from

5. W. huillana, A. DG. in Ann. Sc. Nat. ser. 5, vi. p. 333. An 

 annual with several slender ascending branching stems from 3-6 in. 

 Leaves alternate sessile oblong or obovate-oblong entire or obscurely 

 and distantly toothed, often obtuse, sparsely hairy or glabrous, 2-4

 sule approaches maturity. Calyx about 2 lines long ; tube glabrous 

 acute at the base almost ribless ; lobes 4 oblong one much smaller 

 than the others or altogether wanting, the lateral ones furnished with 

 1 or 2 teeth. Corolla usually shorter, 4- or 3-fid ; tube cylindrical ; lobes
