the claw, very conspicuous in the living plant. Stamens 

 certainly not attached to the petals, though frequently 

 coming off along with them, owing to a part of the re- 

 ceptacle being also torn away. The stem remains during 

 the following summer, sometimes longer. June 15,

What Mr. Wilson has sent me from near Bangor, 

 named R, arif alius with a tnark of doubt, is cer- 

 tainly not so, nor can I find more than a slight 

 difference in size, none in character, between 

 this Welsh plant and the common R, Acetosa^ 

 gathered in Berkshire and elsewhere. 



206. 1. 8, add- 

 Since the above account was published, I have re- 

 ceived from the Rev. Charles Burton, LL.B. of 

 Manchester, and from Mr. W. Wilson of War- 

 rington, various specimens of Alisma repens, 

 gathered about the margins of several lakes in 

 Anglesea. Of these the smaller ones agree ex- 

 actly with the figure in Cavanilles ; but the larger 

 having stems from one to two feet long, and, 

 though prostrate, less disposed to throw out 

 radicles^ approach so nearly to A. ranunculoides, 

 which frequently bears reclining stalks^ if not leafy- 

 ones, that I concur with both my obliging corre- 

 spondents in thinking the A. repens no more than 

 a variety, differing from rammculoides as Ranun- 

 culus reptans does from R. Flammida; see v, 3. 45. 

 It flowers in July and August.

Ray's plant, found plentifully about Halifax, is 

 Pyrola media, of which I have received fine spe- 

 cimens from Mr. Roberts Leyland of that town, 

 who first detected the error. Probably Mr. 

 Lightfoot's Highland P. rotundifolia may, in 

 some instances, have been the media, which was 

 not distinguished in his time.
