remain only the East and North Highland provinces, 

 which can be relied upon ; and within these two provinces 

 it is reported to grow in the counties of Perth, Forfar, 

 Aberdeen, Moray, and Sutherland. As I have collected 

 the species within a few miles of the West Highland pro- 

 vince, near the head of Moray, and there seems no cause 

 wherefore it should not occur within that province, I have 

 reckoned the West Highlands in the provincial estimate. 

 It seems probable that the range of altitude, &c., equally 

 as the area, is yet imperfectly ascertained ; indeed, I have 

 so much difficulty in distinguishing between this plant and 

 S. subulata, that I am unable to use all my own notes on 

 their localities ; lest I should have confused them together 

 in former years. They are probably one species only. '

Native. Glareal and Rupestral. As with the preceding 

 species, the difficulty of satisfactorily distinguishing be- 

 tween them, throws much uncertainty on their distribution, 

 apart from each other. While the range of the former was 

 perhaps too much contracted, that of the present plant may 

 be unduly extended, particularly in respect of altitude ; 

 but 1 feel compelled to carry this up to seven or eight hun-
