Native. Sylvestral. The extreme rarity of this plant 

 in the Highland provinces, where only one locality seems 

 quite to be relied upon, induces the assignment of it to the 

 English type, notwithstanding that there appears no parti- 

 cular prevalence of it in the southern, as compared with 

 the northern, provinces of England. According to Light- 

 foot's Flora Scotica, it was found by Mr. Stuart in Morvern, 

 near the Sound of Mull, " on a dry heathy brae," to the 

 east of the houses of Laggan, — a situation which appears 

 very suspicious for a plant usually restricted to the roots 

 of trees in complete shade. I have a specimen from Camp- 

 sie Glen, which I suppose to be in Stirlingshire, collected 

 by Dr. J. D. Hooker.
