 I have seen no Falkland Island specimens of this plant ; can it be the C. /estiva ?

Dr. Boott has kindly favoured me with the range of this species, which is so wide in the northern hemisphere 

 that we should quite expect that it will hereafter be found along the chain of the Cordillera. Commencing in 

 Greenland on the east, it crosses to Unalaschka on the west by Cumberland House on Bear Lake, and thence runs 

 south along the Rocky Mountains. In Europe it has hitherto been found in Lapland only.

The present, Dr. Boott remarks, is decidedly the European C. curta, one Falkland Island specimen alone, out 

 of very many, differing from the others in having ten spicuke, the average number being six to eight. 



The geographical distribution of this species is very wide, for it inhabits all Europe from the latitude of 

 Lapland, where, according to Wahlenberg, it is excessively common, to the Mediterranean region, which it does 

 not enter. In Arctic America again it is abundant, extending in the. United States as far south as New York.

A species wholly unknown to me, except through the figure and description of M. Brongniart.
