CORNISH FLORA. 69 



Primuhi ehitior, Jacq. I have tested the majority of the 

 Cornish records for this sjjecies and find they are nothing hut 

 P. (icaulis, Linn., var. caulescent (Js.oc\\). P. elatior is restricted to 

 the Oxford Clay, in the counties of Cambridge, Bedford, &c. 



Pneumaria maritinut, HilL Such a northern species is most 

 unlikely to occur in Cornwall. Mr. Pascoe's record to Mr. 

 Watson was based on dried and unlocalized specimens, and Mr. 

 Miiller's plant was found in a flower pot. 



Veronica serpi/llifolia, Linn., var. humifma (Dickson). Soon 

 after the publication of my List I saw living specimens of Mr. 

 Eichards's Lizard plant, and was able to convince that gentleman 

 that it was only a vagrant form of the type. The variety 

 humifusa is quite a northern plant. 



Salcia pratensin, Linn. I included this in my Lint on the 

 strength of the Rev. H. Boyden's record in a paper on "The 

 Flora of the Scilly Isles," read before the Penzance Natural 

 History and Antiquarian Society, an abstract of which appeared 

 in the Society's D-ansartions, 1889-90. Mr. A. Bennett has 

 recently seen Mr. Boyden's plant, and does not hesitate to 

 pronounce it typical S. Verbena ca. 



ChcnopodixDn glaucuin, Linn. Mr. Couch's reiuark {loc. cit.) — 

 " On the beaches by the coast, common," stamps this as a 

 mistake, Mr. F. T. Richards must also have had some other 

 species in his mind when entering it in his list of plants of the 

 Lizard district. Even Devon does not come in its range. 



Ramcx donicstiras, Hartm. In excluding this species I am 

 ac(j[uiescing with the views of the Rev, AV. Moyle Rogers and 

 Mr. James Grroves, who say it is wholly northern. Mr. Watson 

 refused to accept the Cornish and Devon records for his 2opo- 

 grapliical Piotany^ and indeed excluded all records south of 

 Yorkshire. 



CeratophijUum suhnwrsuni, Linn. My List retains this species 

 and excludes C. denwrsuni, Linn., whereas C. subnicrswn should 

 be excluded and C. demersum be retained. C. suhmersum is an 

 eastern counties plant, and not at all likely to favour Cornish soil. 



Allium Scordoprasuni, Linn. No one now doubts that, 

 capable botanist though she was, Miss Warren fell into an error
