B48 NOTES RESPECTING THE ROSES OF PLYMOUTH. 



extremely rare. On a mass of rock above Whitsand Bay, near Rame, 

 C'ovnwall ; also on a bank, by the path, leading through the plantation, 

 to Penlee Point, from Cawsand Village; possibly introduced at the 

 latter station, which, like the other, is in Cornwall. 



2. R. tomentosa, Sm. Common, and generally distributed about 

 Plymouth, in hedges and tliickets, being, after R. canina, R. arvensis, 

 and R. micrantha, our commonest Kose. Some of our plants should, 

 I think, be referred to the variety suhgluhosa, Sm., but the differences 

 between it and the type seem so slight, that I find it difficult to separate 

 the two. The species is extremely variable. One of its forms, R. 

 scabriuscula, Sm., which is as plentiful as ordinary R. tomentosa 

 about Plymouth, is so much unlike the latter in general appearance, 

 that it might be regarded as distinct, did not intermediate forms con- 

 nect the two. About Plymouth I have never seen any form of R. 

 tomentosa, with either quite naked peduncles or pure white flowers. 



3. R. rnbii/inosa, Linn. Eare. Apparently quite wild in a wood 

 near Riverford, Plym Valley, where are two bushes at present (1870) ; 

 one only a few years old, growing very near a spot where a larger bush 

 grew some years ago, from a seed of which it has probably sprung. A 

 fine bush on a hedgebank by the Plymouth and Ivybridge Eoad, near 

 the hamlet of Lee Mill Bridge, in a situation where the suspicion that 

 it may have been sown by a bird can alone attach to it. Two bushes, 

 near together, but on different sides of the Plymouth and Saltash Eoad, 

 about three miles from the former place, both growing on banks where 

 a periodical paring will prevent either from ever producing flowers. 

 There are some bushes of this Rose in a waste spot by the line of the 

 South Devon Railway, near the village of Cornwood, but there they, 

 together with Pastinaca sativa, growing near them, may perhaps mark 

 the site of an old garden. A few years ago a single bush grew amongst 

 bushes of Ulex europceus, on a bank between Knackersknowle and 

 Tamerton Foliott, but it has since disappeared. 



4. R. micranthn, Sm. Quite common, and generally distributed all 

 about Plymouth, being, after R. canma and R. arvensis, our commonest 

 Rose; growing on the shelving slaty banks of our estuaries and creeks, 

 as well as in bushy spots on the borders of Dai'tmoor, in sheltered 

 valleys by our sparkling streams, and in hedges exposed to the salt 

 sea-breezes coming in from the Channel. A variety with quite naked 

 peduncles is scattered over a considerable portion of our district, but I
