On the Highland mountains of Scotland. 



On the mountains of Clova, Angusshire, and at Loch-ne-gare. Mr. 

 G. Don. 



Annual. August. 



Root with numerous fibres. Herb much smaller than any variety 

 of the last that I have seen. Radical leaves on long stalks, very 

 fleshy, convex at the back, roundish-kidney-shaped, quite en- 

 tire ; those of the stems few, more oblong, partly stalked, either 

 ovate, with a tooth at each side, or ovate-oblong, entire, seldom 

 quite sessile. Fl. numerous, one cluster sessile at the root, the 

 rest terminating the very short stems. Cal. purplish. Pet. thrice 

 the size of the foregoing, white, tinged with purple. I have 

 seen but a half-ripe pouch, which resembles C officinalis. 



Linnaeus and DeCandoUe have made this a distinct species. I do 

 not venture to assert that it is so, but the late accurate Mr. Don 

 was of that opinion, and rightly determined it to be theLinnaean 

 plant. The great size and beauty of the Jiowers are remarkable. 

 Dr. Richardson and Dillenius found our supposed variety y of C. 

 officinalis, which some have taken for the grcenland,ica, to remain 

 unaltered from seed in their gardens ; and this report has in- 

 duced me to suspect their plant to have been really the grcen- 

 landica, though they would hardly have omitted to notice the 

 large flowers. Culture, under accurate observation, may settle 

 the whole difficulty; for opinion here is not sufficient.

Radical leaves ovate, entire ; those on the stem sessile, lan- 

 ceolate and toothed. Pouch elliptical, strongly reticu- 

 lated with veins.

well as division, of its usually numerous stems, which are partly
