CAREX 535 



It occurs at Wokingham, Watson, Herb. Kew., Wellington College 

 Station, Tv/nail, at Greenhain Common, Aldermaston, Cothill, &c. ; 

 but all gradations between this and the form with extremely branch- 

 ing panicle, var. composita, S. F, Gray, 1. c, are found. In the 

 Greenham and Cothill plants, which I have placed under var. sim2)lex, 

 the glumes are very pale ; these are the var. pseudo-Boenninghausiana, 

 Watson, 



The tussocks of C. paniculata, in the Pang valley near Bradfield, and 

 in the Lambourn valley near Bagnor and Shefford, are a striking 

 feature in the surrounding vegetation, many being more than a foot 

 high and proportionately broad. 



C. paniculata is found in all the bordering counties. 



C. vulpina, Linn. Sp. PI. 973 (1753). Fox Sedge. 



Gramen palustris Cyperoides, Ger. Em. 21. 

 Top. Bot. 455. Syme, E. B. x. 91, t. 1623. Nyman, 781. Fl. Oxf. 329. 

 Native. Paludal. Sides of canals, rivers, and ditches, marshes and wet 



places. Common and widely distributed. P. May- September. 

 First recorded by Dr. Noehden in Mavor's Ayr. Berks, 1809. Common 

 about Marlow, Mill in PJnjt, i. 994, 1843. 



Var. NEMORosA ^Rebent. exBoott. 111. Carex, iii. 122), Vignea nemorosa, 

 Reichb. Fl. Germ. Exc. 59 (1833^ is not unfrequent ; it has been noted 

 from Coleshill, Appleton, Cumnor, Marcham, Kennington, Southcote, 

 Coleman's Moor, Ruscombe, &c. 



The forms described by S. F. Gray in Nat Arr. ii. 47, as var. decom- 

 posita with awned bracts and compound panicles, var. aristata with 

 branched panicle and awned bracts, and acuta with branched panicle 

 and acute bracts, have also been noticed. The plant with very compact 

 head of panicles appears to be the var. crassior, Anders. Cyperac. Scand. 

 66, 1849. I have seen it near Hurst. A plant with an interrupted 

 .slender spike-like panicle, in which the glumes were tinged with 

 russet brown, suggested a possible hybrid with C. disticha ; it was seen 

 near Ruscombe. 



The fruit is often malformed from the attack of an insect which 

 causes it to become hypertrophied into a horn-like growth. 



C. vulpina is found in all the bordei'ing counties. 



C. muricata, Linn. Sp. PI. 974 (1753). 



C. spicata, Huds. Fl. Angl. 353, not of Linn. 

 Top. Bot. 453. Syme, E, B. x. 93, t. 1624. Nyman, 781. Fl. Oxf. 329. 

 Native. Septal. Ditches, sides of canals and rivers, and hedge-banks 



in dry situations. Not uncommon. P. May-June. 

 First record. Sonning, Mr. S. Budge, Herb. Brit. Mus. 1800 (a scrap of 



C. divulsa is on the same sheet). C. muricata, Dr. Noehden, Mavor's
