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 stern remains during 

 the following summer, sometimes longer. June 15,

What Mr. Wilson has sent me from near Bangor, 

 named R. arifolhis with a max'k 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. Acefosa, 

 gathered in Berkshire and elsewhere.

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 neai-ly 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. rc})ens no more than 

 a variety, differing from ranunculoides as Ranun- 

 culus reptajis does from R. Flamnmla; see v. 3. 45. 

 It flowers in July and August. 



210. after Sagina 2. insert — Rhodiola.

A. monococcum. Cord. Hist. 152. 2.f. 



243. 1. 26— for "Binfield, Berks," read " VirginiaWater." 



248. last line, after Adoxa, insert — Rhodiola. 



255. 1. 17 from the bottom, add — 



Ray's plant, found plentifully about Halifax, is 

 Pi/rola media, of which I have received fine spe- 

 cimens from Mr. Roberts Leyland of that town, 

 v^ho first detected the error. Probably Mr. 

 Lightfoot's Highland P. rotundifolia may, in 

 some instances, have been the media, which was 

 nut disthiguished in his time.
