198 . On the British Species 



Root fibrous. Stems mostly erect., hoary with long spreading hairs, 

 usually glandular. Leaves ovate, often very broad and usually ob- 

 tuse, the lower ones narrowed into a petiole. Flowers aggregated or 

 in dichotomous panicles, upon short stalks, which never exceed the 

 calyx. Sepals lanceolate, acute, entire, the outer ones very slightly 

 membranous, the inner rather more so, hairy throughout. Petals 

 white, scarcely longer than the calyx. Capsule cylindrical, slightly 

 curved upward, about twice the length of the calyx. Seeds very 

 small, tuberculated. 



In fields, on dry banks, &c. common. April — September. 

 2. C. viscosum, Linn. Sm. — Leaves oblong, lanceolate, petals 

 about as long as the calyx, sepals oblong-ovate, and, together with 

 the bractese, membranous at their margins and glabrous apices, cap- 

 sule cylindrical, curved, about twice as long as the calyx, fruit-stalks 

 longer than the calyx.

 Root fibrous and stronger than in C. vulgatum. Stems diffuse, and, 

 unless supported by other plants, prostrate, with their extremities 

 ascending, of a much darker green than the preceding, and covered 

 with shorter pubescence, usually without any glands. Leaves oblong 

 or lanceolate, frequently acute, the lower ones narrowed into a pe- 

 tiole. Flowers collected in small terminal panicles, not forming dense 

 fasciculated heads, as in C. vulgatum, upon stalks which are longer 

 than the calyx. Sepals oblong-ovate, rather obtuse, entire, the apex 

 and margins, particularly the inner one, broadly membranous, but 

 slightly hairy and usually quite glabrous at their tips. Petals white, 

 scarcely longer than the calyx. Capsule as in the preceding species. 

 The seed, according to Gaudin, beautifully muricated, and of about 

 half the size of that of C. vulgatum. 



The whole plant is sometimes glandular, more particularly upon 

 the peduncles and calyx, when it forms the variety glandulosum of
