70 CORNISH FLORA. 



when reporting this plant for " Perran Minor." Topographical 

 Botany does not countenance it for any count}' south of 

 Lancashire. 



Thesium humifusum, DC. Mr. Pascoe included this species 

 in his Catalogue to Mr. Watson, and the following remark 

 concerning it occurs in Keys' Flora of Devon and Cornwall : — 

 "I learn from Mr. H. C. Watson that a specimen from this 

 county [Cornwall] was sent to the Bot. Soc, Lond,, by Eev. T. 

 Butler." On such slender evidence, it is no longer entitled to 

 rank as a Cornish species. Topographical Botany shows that Mr. 

 Watson doubted the record. 



Fritillaria Meleagris, Linn. Mr. Pascoe included this in his 

 Catalogue to Mr. Watson on the strength of dried, undated, and 

 unlocalized specimens, said to have been gathered somewhere in 

 the county. 



Potamogeton alpinus, Balb. Yet another of Mr. Pascoe's 

 unlocalized records to Mr. Watson. No other botanist has been 

 able to find a trace of the plant in Cornwall, and Topographical 

 Botany questions it for the two westernmost counties. 



P. colorattis, Hornem. Mr. Wise has written me recently 

 saying he was in error when recording this for Cornwall. 



P. heterophyllus, Schreb., P. prcelongus, Wulf, P. Jiliformis, 

 Nolte, and ZannichelUa polycarpa, Nolte, must all be dropped as 

 Cornish plants. It is only fair to Mr. P. T. Richards to add that 

 they were admitted into my List as possible Cornish species 

 rather than as actual ones. When botanizing in the Lizard 

 district some years ago Mr. Pichards found plants agreeing, as 

 he thought, with the descriptions of these, but he unfortunately 

 did not preserve specimens. 



Carex acuta, Linn. Dr. Vigurs informs me that I misunder- 

 stood his note, which was intended to refer to C. acutiformis, Ehrh. 

 As the claims of C. acuta to Cornish soil now rest on Mr. Pascoe's 

 solitary and suspicious record, I fear it must be omitted. 

 Topographical Botany doubts it for Devon and Cornwall. 



Chara connivens, Braun, C. contra ria, Kuetz., and Nitella 

 capitata, Agardh, must no longer be considered Cornish subjects.
