On the mountains of Scotland and Wales, by the sides of alpine 

 rills, plentifully. 



By rivulets on the declivities of Snowdon. Mr. Llwyd. No where 

 more plentiful than about springs on the lofty mountain of 

 Widnah, towards the north. Dr. Richardson. On Ben Lomond,

 Hooker. 



Perennial. June, July. 



Root creeping, crowned with tufts of round leafy stems, some of 

 them 3 or 4 inches high, bearing sometimes a solitary^oit'er, 

 sometimes 2 or 3, in a forked, partially bracteated panicle. 

 Leaves elliptical, ^ an inch or more in length, varying in 

 breadth and acuteness, sessile, light green. No plant varies 

 more as to pubescence. Mr. Llwyd originally remarked that 

 some individuals were green, others hoary. The Linnaean speci- 

 men is perfectly smooth ; others from Wales, Scotland, and 

 Switzerland, quite hoary, even shaggy with long woolly, or 

 silky, jointed hairs, as in Lightfoot's figure. The hairs are too 

 short in the plate, executed by Dillenius, in Ray's Synopsis. 

 The calyx-leaves are elliptical, scarcely pointed ; either hairy or 

 smooth ; the inner ones more especially bordered with a white 

 membrane. Pet. inversely heart-shaped, much longer than the 

 calyx, white and handsome. Stani. 10, all perfect. Styles 5. 

 Caps, cylindrical, curved, twice as long as the permanent calyx, 

 opening with 10 lanceolate blunt teeth. 



The hairy variety has often been taken for the following species. 



7, C. latifolium. Broad-leaved Mou.se-ear Chick- 

 weed, 



Leaves elliptical, rough with short bristly hairs. Flower- 

 stalks terminal, simple, mostly solitary. Capsule ovate 

 at the base.
