A CONTRIBUTION TOWARDS A FLORA OF THE 



TEIGN BASIN, S. DEVON. 



By the Rev. W. Moyle Rogers, F.L.S. 



(Concluded from p. 243.) 



As since I began writing this paper I have moved my home 

 from the banks of the Teign to those of the Tamar, and so can 

 hardl}^ hope to make any further contribution towards a Flora of 

 the Teign Basin, it may be desirable that I should here add to the 

 foregoing notes on the less common plants the two lists following : — 



I. Roses of the district, as observed by me (1876-1881). 



Piosa tomentosa, Sm. (aggregate). — Grenerally distributed, and 

 usually rather common. Of the clothy-leaved forms in the district, 

 E. cuspidatoides, Crep., appears to me the best marked and most 

 constant in character. It is rather frequent in the parishes of 

 Christow, Asliton, and Trusham. Bushes by the Teign near Chag- 

 ford (frequent), by the roadside between Moreton and North Bovey, 

 and by the Bovey near Bovey Tracey, appear to be all rather 

 glandular forms of 11. subr/lobosa, Sm. But most of the downy 

 thick-leaved plants of the district may best be ranged under typical 

 R. tomentosa, Sm., as described in Baker's ' Monograph,' though 

 frequently more glandular than that. Of the thin-leaved forms 

 R. sylvestris, Woods, occurs in good quantity at the bottom of Teign 

 Lane, Trusham, and in fields to the east of Chudleigh ; and very 

 well-marked E. scahriuscula, Sm., is abundant on Black Lea Down, 

 Trusham, and also occurs occasionally in the parishes of Ashton, 

 Hennock, and Chudleigh. 



R. riihiginosa, L. — The only place not actually in or close to a 

 garden where I have seen this is the hedge of a field between Chud- 

 leigh Bridge and Chudleigh Knighton, 



R. micrantha, Sm. — Rather common on Bovey Heathfield, on 

 Knighton Heath, in Hennock, and in all the parishes on the western 

 slope of Haldon ; Ilsington, Briggs. On Haldon and on Black 

 Lea I have met with some small bushes agreeing with Baker's 

 description of R. hystri.r, Leman, except in having a few haii'S on 

 the leaves beneath. I have seen no naked-peduncled form. More 

 frequent in rough bushy ground and among furze than in lanes and 

 fields. 



R. canina, L., a. lutetiana, Leman. — Common. 



c. sphcBrica, Gren. — One large bush near the river by Teign Bridge. 



e. dumalia, Bechst. — Very common everywhere. Tlie small 

 white-flowered form referred to in Fl. Plym. (p. 137) is frequent. 

 In the valley between Chudleigh and Crocombe Bridges are some 

 bushes with the foliage of dumalis, and globose fi-uit with densely 

 viUose styles, specimens of which M. Deseglise has named R. 

 eriostyla, Des. & Rip. 



f. hiserrata, Merat. — On both sides of the river between Sparrow 

 and Crocombe Bridges ; frequent. Quite common in Trusham,
