On dry stony alpine heaths. 



Four riiiles from Heptonstall near Widdop, on a great stone by the 

 river Gorlpe, Lancashire. Merrett. Shown to Ray, on the same 

 spot, by T. Willisel. R. Sijn. Common throughout the High- 

 lands, and \'l'estern Isles, of Scotland • also in the isle of Mull, 

 at the end next Y-Columb-kill, for the space of several miles, 

 (w^here it was observed by Mr. Lhwyd) ; and at the top of East- 

 Common-Wood, a mile from Hexham, Northumberland. Light- 

 foot. Sent from Durham, by the Rev. Mr. Harriman and Mr. 

 Oliver. 



Shrub. June. 



Stems woody, round, branched, long and trailing, with a smooth 

 bark. . Leaves alternate, stalked, obovate, obtuse, entire, thick 

 and rigid, veiny, evergreen ; convex and wrinkled above -, con- 

 cave and paler beneath j their edges very minutely downy. 

 Scales of the buds lanceolate, acute, permanent. Siipidas none. 

 Clusters terminal, short, drooping, with many acute, coloured 

 bracteas. Flower-stalks angular. Segments of the cali/x pale, 

 often fringed. Cor. rose-coloured, smooth. Berry globose, de- 

 pressed, scarlet, mealy within, very austere and astringent, left 

 untouched by birds. Seeds seldom more than 4 or 5 perfected, 

 though there are rudiments of 8 or 10, so that the character of 

 Tournefort's genus Uva Ursi, as given by Linnaeus in Gen. PL, 

 does not hold good.
