384. Callitriche platycarpa, Kutz. (C. stagnalis, Scop.)

 F. A. Lees. 



III. Bradley, Linton. 



385.* Callitriche obtusangula, Le Gall. 



III. The specimen in Mr. Bloxam's herbarium as C. verna 

 is, I think, undoubtedly this species. I have compared it 

 with Messrs. Grove's Hampshire plants and do not question 

 their identity, Purchas, J. B. 



386. Callitriche autumnalis, L. Repton F. and F. ; wants 

 confirmation ! 



387. Ceratophyllum demersum, L. (Hornwort). Native. 

 English type. Range 1. 



III. There is a scrap in Mr. Bloxam's collection labelled 

 from " Ponds in the Tickenhall Lime-works," which, although 

 labelled " Chara vulgaris," is evidently this plant. I did not 

 myself meet with it, but it may well have died out, Purchas, 

 J. B. 



ORDER LYTHRACEJE. 



Ly thrum hyssopifolia, L. Alien. 



III. Near Calke, Rev. A. Bloxam, communicated by 

 Mr. Harris. A single plant only was found by the 

 Rev. A. Bloxam! as recorded in N.B. G., p. 637. The 

 spot, however, was not " in Calke Park," but on the side of a 

 pond long since let dry, and was " two fields below the mill at 

 Calke. Mr. Bloxam described the spot to me, and I searched 

 it, but, of course, without surprise that a plant known to be 

 so capricious and uncertain in its appearance was not again 

 to be found there," Purchas, J. B. 



390. Lythrum Salicaria, L. (Purple Loose- strife). Native. 

 English type. Range 1. 



II. Kirk Hallam and Sandiacre, Hasse. 



III. Burton-on-Trent, Harris', Little Eaton near Derby ! 

 Pond at Calke Mill, Purchas, J. B.; Osmaston-by-Ashbourne, 

 Linton.
