with Brittany and Normandy by means of the Channel Islands, and manifesting such 

 connection by the following plants : — Trichonema Columnae, Iris fcetidissima, Aspleni- 

 um lanceolatum, Erodium moschatum, Herniaria ciliata, Scilla autumnalis, Arthrolo- 

 bium ebracteatum, Lotus angustissimus, Hypericum linariifolium, &c. To enter into a 

 detailed account of the geological aspect of the district would be superfluous, as Jones 

 in his Flora has been at some pains to describe it accurately as regards Devon, and 

 with the exception of the serpentine of the Lizard, the same remarks may be supposed 

 equally applicable to the county of Cornwall. 



The number of Phanerogamous species described in the ' Flora Devonensis,' 

 amounts to 774 : to these must be added 41, for species since detected in the same 

 county, or separated from others of which they were supposed to be mere varieties. 

 Of these 41, 15 are also found in Cornwall. There are also 31 species peculiar to the 

 latter county, not natives of Devon. The western Flora would therefore contain 846 

 species, — a number certainly not too great for the extent of surface included within its 

 limits, and the variety of soil and other peculiarities which it presents. 



Jones adopts the Linnaean classification, which, for convenience, I shall now follow 

 in enumerating the additions &c. made since the publication of his work. 



Veronica Buxbaumii, Ten. Occurs both in Devon and Cornwall, but not abun- 

 dantly : it appears limited to the fields which have been recently ploughed, and disap- 

 pears in a season or two. 



Veronica polita. Fries. Not uncommon in this neighbourhood. 



Pinguicula vulgaris^ Linn. Mr. Ward found this plant in a bog near Ilfracombe, 

 on the road to Morthoe. I had previously heard that it grew there. 



Trichonema Columna, Reich. On the Warren at Dawlish. No plants were found 

 there last year. 



Fedia Auricula, Gaud. Lindulph, Cornwall, according to the Rev. Mr. Bree. 

 Bolt Head, Devon, Mr. Babington. 



Scirpus Holoschcenus, Linn. Jones says of this plant that it is now probably exter- 

 minated at Braunton Burrows, its only habitat, by draining and cultivation, as a search 

 for it in the summer of 1820 was unsuccessful. Watson, in his Botanist's Guide, 

 gives the following directions : — " Braunton Bun'ows, in hollows or flats among the 

 sand hills. The keeper of the light-house knows the plant, and pointed out one of 

 the stations to me about half a mile to the right of the light-house." I easily found 

 this spot last autumn, which I believe to be the only one where the plant is now to be 

 found. Miss Hill writes me concerning it as follows: — " The large spot where those 

 rushes grew is now covered with blown sand, but a new place has been found. I do not 

 think the present plants so large as those I have collected at the old spot thirty years 

 since, and much within that time." 



Cyperus longus, Linn. Miss Warren informs me that it grows near Truro, Cornwall. 



Scirpus Savii, Spreng. Common on the borders of Dartmoor : Cornwall. 



Briza minor, Linn. Near Torpoint and Truro, Cornwall. 



Cynosurus echinatus, Linn. Under the Hoe, Plymouth, but I fear an outcast from 

 a garden. 



Avena pubescens, Linn. Catdown Quanies, Plymouth. 



Brachypodium pinnatum, Beauv. I have never seen this plant in Devon, where 

 Jones says it is common. 



Bromus velutinus, Schrad. var. j3. On the Cornish clifis. Sir W. J. Hooker and 

 Mr. Johns, who first directed attensiou to it, now think it only a variety of B. mollis.
