DECANDRIA-^PENTAGYNIA. Cerastium. 335 



On Clogwyn y Garnedd, a very high mountain near Llanberris, 

 Caernarvonshire. Dr. Richardson, and Mr. Griffith. On the 

 Highland mountains. Mr. Mackay. Professor Hooker suspects 

 it to be rare in Scotland. 



Perennial. Juiie, July. 



Rather more dwarf and tufted than the foregoing, of a yellowish 

 hue, from the rough clothing of short, tawny, rigid hairs, always 

 present, as far as I have observed. Leaves broader and more 

 obtuse. Flower-stalks long, hairy, and viscid, almost always 

 solitary, and without bracteas. Fl. like the last. Caps, straight, 

 sometimes not much longer than the calyx, as in the Linnsan 

 specimen ; but it is often considerably longer, and rather cylin- 

 drical than ovate, though hardly curved. I have ripe capsules, 

 differing in length, on the same specimen, and am doubtful 

 whether the character of the " ovate capsule" ought to be 

 trusted, unless that term be restricted to the base of the fruit ; 

 but then it applies almost equally well to C. alpinum. 



8. C. aquaticum. Water [Mouse-earjChickweed. 



Leaves heart-shaped, sessile. Flower-stalks lateral, soli- 

 tary. Capsules drooping, ovate, with five cloven teeth. 

 Petals deeply divided.

In watery places, and the margins of rivers and ditches. 



Perennial. July. 



Root creeping. Stems weak and straggling, 2 feet long, more or 

 less, branched, forked, leafy, round, covered with prominent 

 viscid hairs. Leaves heart-shaped, acute, wavy, hairy, of a 

 bright pleasant green, all sessile, except a few of the lowermost 

 occasionally. Flower-stalks lateral between the leaves, single- 

 flowered, hairy and viscid all over ; bent downwards after flower- 

 ing. Calyx-leaves ovate, acute, hairy, slightly bordered. Pet. 

 about the same length, white, in 2 deep, narrow, bluntish, 

 spreading lobes. -S ton. always 10 j and styles 5. Gzps. ovate, 

 about the length of the calyx, or longer, opening with 5 teeth, 

 each of which I have lately found to be cloven, though not so 

 expressed in Curtis, or in Engl. Bot. 



The general appearance of this plant much resembles Stellaria 

 nemorum,p. 300, and it is remarkable that LinnEeus once con- 

 founded them, including S. media ; which only shows that at
