206 RUBUS ERYTHRINUS. 



There are few characters by which to separate it from R. 

 rhamnifolius W. & N., Anglor., but it has a markedly different appear- 

 ance from the ordinary form of that bramble, partly by reason 

 of the leaflets having dentate or irregularly dentate-serrate, not 

 finely cut and very regular, divisions. It is also unlike it in 

 having piuk or tinted petals, and in the leaves being less frequently 

 felted. 



I quote Dr. Focke as the authority for considering the plant 

 about which I am writing as essentially the R. erythrinus of 

 Genevier ; yet a reference to the work of the latter, ' Essai Mono- 

 graphique sur les Rubus du Bassin de la Loire ' (I have only ed. 1, 

 1869, to which to refer), will show some want of agreement between 

 my description of the Plymouth plant and his of R. erythrinus, and 

 the points of dissimilarity would have made me hesitate to combine 

 the two on my own responsibility. 



This bramble is extremely abundant, and grows with great 

 luxuriance, in many parts of Cornwall and Devon, evidently finding 

 in these south-western counties conditions well suited to its 

 requirements. Apart from the neighbourhood of Plymouth I have, 

 in Cornwall, seen it in plenty near Bodmin, in the parishes of 

 Blisland, St. Tudy, St. Mabyn, and Cardinham ; also in abundance 

 in the neighbourhood of Launceston.

 Hiern, from the parishes of North Moltou, N. Tawton, Symbridge,

 collected in company with the Rev. R. P. Murray in 1883.

 Movie Rogers and myself in 1886. In the following year I saw it 

 also, but in small quantity, at Branksome Chine.

 tity by Lyndhurst Road Station, whence I have seen a specimen. 



Gloucester. — Mr. Jas. W. White, in his ' Flora of the Bristol 

 Coal Field,' says : — " We have gathered by the river side under 

 Cook's Folly the bramble mentioned by Mr. Briggs, under R. Lind- 

 leianns, in the ' Flora of Plymouth,' as very common about Plymouth, 

 and probably an undescribed species " (p. 58). I have seen a 

 specimen from this station.
