Hore go far in evidence of this variety or species being a 

 true native. In the Phytologist (ii. 237.) Mr. Hore writes, 

 "As to this Tiifolium being decidedly indigenous, the 

 shadow of a doubt cannot be entertained by any one 

 who has seen it growing in another locality near Kynance 

 Cove, which we subsequently detected. There, on the 

 side of a ravine, quite out of sight of any land which has 

 been cultivated, it grows in the greatest luxuriance, 

 forming a large portion of the herbage. Years and years 

 must have elapsed under the most favourable circumstan- 

 ces to have allowed it to have taken possession of such a 

 residence, and to have ejected the previous possessors, 

 supposing that it had been cultivated within a moderate 

 distance of this locality. But the summit of the cliflF ap- 

 pears never to have been broken by the plough, and the 

 turf is as compact and solid as can be imagined, producing 

 the ordinary plants of the district. I also made inquiries 

 respecting the cultivation of the Trifolium iocarnatum, and 

 found that it was not known in the neighbourhood." It 

 may be worth inquiry, whether this be the Trifolium stra- 

 mineum of Presl, of which I have never seen specimens.
