C. Goodenowii is a very variable plant ; in our marshes and bogs in 

 the south of the county it appears often as a densely caespitose plant, 

 with culms 15-18 inches high, which in the extreme form is the 

 var. ULiGiNosA = C. vulgaris, var. uliginosa, Syme, 1. c, which may be 

 synonymous with C. juncella, T. M. Fries, in Bot. Notiser (1837) 207. 

 This has been seen at Windsor Park, Burghfield, Inkpen, Sunning- 

 hill, Sandhurst, Early, Bagshot, and Long Moor, but the more frequent 

 plant has broader leaves, and is rather similar to the var. tricostata, 

 which is a Scandinavian plant. 



An analogous form to the var. viridis of C. acuta occurs in this species, 

 viz. the var. chlorostachya, Reiclib. Ic. Fl. Germ, et Helv. viii. 6, 

 f. 579, nom. solum, which has paler and shorter glumes and more 

 prominent and greener perigynia; this and the form pohjgama, Reichb. 

 1. c. 580 b, have been seen at Cothill, near Radley, Bucklebury, &c. 



A small form from Wytham, with leafy bracts and stout spikelets 

 with large perigynia, is allied to the var. teres, Reichb. figd. in Boott, 

 Carices, 142. 



Although not a common species in the same way that C.Jlacca is, yet 

 C. Goodenowii is found in many localities in all the districts, and is 

 especially frequent in the boggy district of the south-west. 



C. Goodenoicii occurs in all the bordering counties.

Native. Pascual, &c. Pastures, roadsides, chalk downs, heaths, &c. 

 Rather partial to clay or stiff soils, but occurring not only in very 

 wet, but also apparently dry soils. Common and generally 

 distributed. Found at 900 feet on Gibbet Hill. P. April-May. 



First record. Near Hinksey. A spec, on the sheet of C. panicea collected 

 by Prof. Bobart in Herb. Oxf. about 1690. C. recurva, Dr. Noehden,

 G. G. Mill in PInjt. i. 994, 1843.
