Native. Pratal, &c. An obscure or puzzling species, 

 by some botanists supposed to be a hybrid form between 

 C. pratensis and C. palustris. Represented in some, per- 

 haps in most, herbaria, by luxuriant forms of C. pratensis, 

 which on this account have been recorded in the ' London 

 Catalogue of British Plants,' under name of Pseudo- 

 Forsteri, placed as a variety of C. pratensis. In Garner's 

 Natural History of StaflFordshire, the habitat of " Burton, 

 Mr, Brown" is recorded for C. Forsteri ; and the name is 

 checked by Dr. Bromfield in a list of British plants marked 

 for the Isle of Wight, probably on the authority of Rev. 

 G. E. Smith. (See Phytologist, iii. 501). I have not seen 

 specimens from either habitat; but if true C. Forsteri oc- 

 curs in them, these constitute the north, south, and west 

 limits, so far as ascertained. Mr. J. S. Mill has recorded 

 (Phytologist, i. p. 61) that he saw C. Forsteri " growing 

 by hundreds in a piece of marshy ground formerly part of 

 Ditton Common; at least it was the plant I previously 

 found near Weybridge and sent to Sir William Hooker." 

 The Ditton locality, as mentioned by Mr. Mill, is familiar 

 to me; and I can say confidently that it is the luxuriant 

 form of C. pratensis (var. pseudo-Forsteri) which grows 

 there. A specimen is in my herbarium, given to me seve- 

 ral years ago by Sir William Hooker, labelled from near 

 Weybridge, which is also C. pratensis. But the plant 

 which is considered to be true C. Forsteri, by the Rev. W. 

 H. Coleman and myself, has occurred in Surrey ; a single 

 root having been found by myself in a field by Whitmoor 

 Pond, near Guildford, where I then and subsequently 

 sought in vain for a second. Mr. Coleman has found a 

 very similar plant " in the Gargle Wood, and in an ad- 

 joining pasture called the Gargle West Field, on the farm
