NOTES RESPECTING THE ROSES OF PLYMOUTH. 349 



have not as yet ever fouiul this across the Tamer. At Bickleigh it 

 occurs with subglobose fruit. All the naked-peduncled plants I have 

 examined have had the sepals destitute of setse on the back, whereas 

 ill the ordinary form they seem always to have them. The two 

 plants often occur in the same hedgerow, and I have met with 

 both on limestone and on slate. A very luxuriant naked-pedun- 

 cled plant, growing at Rumple, in the Plym Valley, is the variety 

 Briggsii of Mr. Baker's Monograph (Journ. Linn. Soc., Botany vol. 

 xi. p. 222). In the neighbourhood of Plymouth I sometimes find 

 R. micrantha instead of R. rubiginosa, the " Sweet Briar" of cottage 

 gardens. 



5. R. canina, Linn., var. hitetiana, Leman. One of the commonest 

 forms of canina in the Plymouth district. Var. spJiarica, Gren. A 

 plant gathered by me near Modbury, about eleven miles to the east of 

 Plymouth, and sent to Mr. Baker, has been pronounced by him to be 

 this. (Journ. Linn. Soc. Botany, vol. xi. p. 227.) Var. senticosa, Ach. 

 A Hose from a hedge near Yeo, about eight miles to the east of Ply- 

 mouth, Mr. Baker identifies with this. (Journ. Linn. Soc, Botany vol. 

 xi. p. 227.) Var. dumalis, Bechst. Very abundant about Plymouth; 

 often with nearly white flowers. Var. urbica, Leman. Common, but 

 not so general as the last. Var. arvatica. Baker. Very rare. Some 

 bushes on top of a hedgebank between "Wiverton and Blackpool, 

 Brixton. They differ from most of the North of England examples 

 in having leaves that are glaucous on both sides ; still Mr. Baker, who 

 has had specimens from me, pronounces them to be " good arvatica.'^ 

 Var. toinentella, Leman. Local and rare. Three bushes a short dis- 

 tance below Lee Mill Bridge, by the path as you ascend from the 

 valley of the Yealm towards the lane leading from Yealmpton to Ivy- 

 bridge, and several others in a hedge by this lane, near the cross-road 

 to Modbury ; also two bushes in a hedge on the left of the lane lead- 

 ing from the Plymouth and Ivybridge Road, by Blackpool, towards 

 Yealmpton, just after you pass the cross lane in front of Wiverton 

 House ; and one or two more, judging from barren shoots only, in a 

 hedge by the Plymouth and Ivybridge Road, near Lynham Lodge. 

 Var. verlicillacantha, Merat. Rare. In a hedge by a lane leading 

 from Pcnnycross to Woodlands ; in another near Harestone, Brixton ; 

 in a hedge near liemerdon House, Plympton St. Mary. In two places 

 on the ascent of the hill toward St. Mellion Village from Renter's Cross,
