et breve aristata. Vvdunculi glabri, nitidi, unitlori, in 

 a?stivatione curvati. Calyx puhe hiwissima lev iter in- 

 structus : laciime ovatir. acuta-, mutiea\ Petaia ova- 

 lia. alba, triplinen ia, apice extus rosea : nervis timpli- 

 cibus, strict is. 



This species approaches near to the preceding - . but having 

 proved it in cultivation, I am now fully satisfied of its being a 

 distinct species. Its habit is so different, that it may be known 

 at all times of the year by it alone. Its turculi are three times 

 shorter than those of hyphoides, always quite smooth and green, 

 never red, and destitute of the bulbous buds SO remarkable in 

 S. hypnoides. 'The latter species is found alike in the plains, as 

 well as on the tops of mountains. The 8, condensate, on the 

 contrary, is met with only in elevated regions. It is not eon- 

 fined to one spot alone, but extends over all the Scottish moun- 

 tains. 



106. S. elongella, surculis erectis brevibus, foliis radicalibus 

 5- tri-fidisve ; surculinis plerumque tridentatis: dentibus 

 mucronulatis, laciniis calycinis ovatis muticis, petalis 

 obovatis.
