 Habitat in paludibus alpinis Scoticis, rariCls.

" The Root consists of woolly fibres, and has the appearance of 

 being perennial. Stetn very slender, a foot or more iu heio^ht, 

 naked, except at the base and summit. Radical leaves but one' 

 or two, much shorter than the stem, narrow, flat, slightly thick- 

 ened, or somewhat involute, at their edges, not channelled. 

 The topof the5/effj terminates in a few racemose forked branches, 

 with two or three leaves at the base. Flowers solitary, mostly 

 sessile. Cahjx-kaves sharp-pointed. Valves of the Capsule blunt 

 and eraarginate. 



" Found by Mr. G. Don in 1795 or 1796, by the side of a rivu- 

 let in marshy ground, among the mountains of Angus-shire, but 

 very rarely. It appears to us to be a nondescript : but we re- 

 ceived from Mr. Dickson, some years before the above date, a 

 specimen not so far advanced towards maturity, of what seems 

 to us the same species. 



"The inflorescence and fructification of this Rush come nearest 

 to bufonius, t. 802. ; but the fewness of the flowers, taller stem, 

 and flatter leaves, as well as the broader and emarginate valves 

 of the fruit, serve well to distinguish it ; not to mention the pro- 

 bably perennial root. Eng. Bot. I. c." 



This species is unknown to me, except from the description I 

 have here quoted. I may however add, that it is not the gracilis 

 of Roth Germ. i. 155. ii. 402., which is J. capitatus, Willd. ; nor
