Descends to the coast level, in the Peninsula.

Eange of mean annual temperature 51 — 47. 



Native. Paludal, Uliginal. Thinly distributed through 

 great part of Britain, with wide intervals of absence, ex- 

 tending even to whole provinces, according to existent 

 records. Perhaps it occurs in more than 30 counties; 

 having been reported from 28 already ; but the estimate 

 of 40, the next upward step, seems not warranted by what 

 is at present known of its localities. Carex Ehrhartiana, 

 said to be a variety of C. teretiuscula, has been found near 

 Manchester ; also, if I rightly know that variety, it oc- 

 curred on Wimbledon Common, in Surrey, some few years 

 ago, in a drying up swamp.
