On the Welsh and Scottish mountains. 



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

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

 Highland mountains. Mr. Mackaij, Professor Hooker suspects 

 it to be rare in Scotland. 



Perennial. June, 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 Linngean 

 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.
