 C. hinervis is a variable sedge, but its range of variation in Berkshire 

 is limited compared with that which is found in the highlands. About 

 Sandhurst and Bagshot it occurs as the large heath plant /. elatior, 

 mihi, and at Broadmoor I found a very broad-leaved form. At Sand- 

 hurst a form with compound spikes has been met with. 



C. hinervis is recorded for all the bordering counties, 



C. distans, Linn. Sp. PI. 1387, ed. 2 (1762), and Syst. ed. 10, 1263 (1760).

Native. Paludal. Marshy fields. Local, with a rather limited dis- 

 tribution. P. June-.July. 



First certain record. Marcham, the author in Rep. of Bot. Record Club, 

 1885. (The name is included on Dr. Noehden's authority without 

 locality, and almost certainly in error in Mavors Agr. Berks, 1809.) 



1. Isis. Near Buscot, and probably elsewhere in the Thames 



meadows. 



2. Ock. Marcham, G. C. Bruce. The specimens were reported on as 



follows : ' This is that robust form, rivalling hinervis in size (but 

 very diiferent from that in fruit and glumes\ which is in 

 England solely an inland or fresh-water plant. Its stout, 

 cylindric, erect spikelets well filled with large green perigynia, 

 lacking the spikelet low down of the salt-water type, its fulvous 

 glumes and longer leaves, all suggest an overgrown Horn- 

 schuchiana,' F. A. Lees in Rep. of Bot. Rec. Club, 1885. In some 

 fields near Abingdon.
