Silvery alpine Jungcrrtiannia. Jnglis. 



Upon the moift: rocks by the fides of rivulets, on 

 the Highland mountains frequent, as on Ben- 

 Lomond^ Goatfieldy in Arran, &c. IX. X. 



The ftalks grow in tufts, from one to two inches 

 high, ered:, cylindrical, about the thickne!: of 

 a filken thread, havirig a few irregular branches, 

 clofely imbricated all around with minute con- 

 vexo-concave leases, of a ftiining filvery colour, 

 relembling the BR YUM argenteum. Tiie roots 

 or bottom of the ftalks are black and fibrous. 



TVe anthers are fufcous, fupported on white pel- 

 lucid peduncles, i-8th of an inch long, arifing 

 from finely indented vaginae, which grow on the 

 fummits of the branches* 



The plant, when dry'd, lofes its glofs, becomes 

 brittle, and turns to a grcenifh grfey colour. 



There is either a very fingular variety of this, or 



elfe a diftincfl fpecies, found not unfrequently 



upon the dry rocks on the Highland mountains, 



and which is taken no notice of by authors.
