C. alpinum of the French botanists, while the silky one is the C. 

 tomentosum Lam. . 



7. C. latifoUum L. (broad-leaved alpine C.) ; subMabrous or 



clothed with short ri^rid yellowish pubescence, stems prostrate 

 csespitose, leaves elliptical- ovate, branches mostly sinf>"le- 

 flowered, bracteas herbaceous, capsule cylindrical oblong nearly 

 straight, E. B. t. 473. 



Mountains of Wales; Clogwyn y Garnedd, and Clogwyn duV 

 arrdhu, Snowdon, but rare. Ben Lomond, Ben Nevis, Ben Ghio, 

 &c., in Scotland. 1^. 5 — 8. 



Never clothed with long white hairs, 



of a deeper green than C. alpinum, sometimes almost glabrous. The 

 stems are dichotomous and bare of leaves below, and much buried 

 under rocks and stones. Flowers solitary, rarely 2, terminal on the 

 branches; when more than one the bracteas are generally oval and 

 foliaceous. " Seeds large, rugose." JI. Watson, A dwarf varietv 

 occurs in Unst, Shetland. We agree with Mr. W. Wilson in think- 

 ing that there exists scarcely any difference either in flower or 

 fruit between this and the preceding. In both, the capsules are 

 broadly oblong, shining, almost twice as long as the calyx, and nearly 

 straight. 



8. C. trigynum Fries (Stitchwort C) ; stems decumbent with 

 an alternate hairy line, leaves oblong-spathulate, peduncles 2 

 or 3 mostly terminal downy, styles mostly 3. Stellaria ceras-

of that great range. 



Breadalbane mountains of Scotland, and mountains to the north 



%. 7, 8, — Stem 4 — 6 inches long, the lower 

 part bare of leaves and much branched. Leaves glabrous or hairy, 

 subsecund and subfalcate, as observed by Wahlenberg; their points 

 callous. Flowers large, pure white. Sir J. E. Smith states that the 

 styles are sometimes 4 or 5 ; and the capsules, in our specimens, have 

 usually 6, but some 8 or 10 teeth.

Sepals 4 — 5, imbricated in aestivation, persistent. Petals 

 4—5, with a twisted aestivation, very fugacious. Stamens 4 — 5, 

 united at the base into an hypogynous ring, with small teeth 

 (abortive stamens) between them. Ovary with. 3 — 5 cells, and 

 as many styles. Stigmas capitate. Capsule globose, crowned 

 with the permanent base of the styles, 3 — 5-celled ; each cell 

 partially divided into 2 by a spurious dissepiment, and opening 

 with 2 valves at the apex. Seeds 1 in each spurious cell, in- 

 verted. Embryo straight, large, thin, with little or no albumen. 

 — ■ Mostly herbs, with entire leaves and without stipules. — 



Linum catharticum is a purgative : i. usitatissimum is the com- 

 mon Flax.
