ftOTES ON BRISTOL Pt.\NTS# ll 



published in Journ. Bot., April, 1890, as corresponding almost 



exactly with the German ajfinis that he had seen at Weike's original 

 stations. 



*R, Cariensis Rip. & Genev. S. Occurs abundantly on the peat- 

 moors near Shapwick. A very remarkable bramble, connective, 

 apparently, of ajfinis witk the lihamnifolii. A similar form found by 

 the Rev. W. Moyle Rogers in great quantity near Lynton, N. Devon, 

 in 1881, was referred to Cariensis by Dr. Focke. The stem is erect- 

 arcuate, pilose, with quinate leaves. Terminal leaflet rhomboidal- 

 roundish, or orbicular, subcordate, subcuspidate. Panicle lengthy 

 in proportion to the usually rather short flowering shoot, with long 

 ascending many-flowered corymbose branches, the upper ultra- 

 axillary ones often greatly exceeding the terminal flower. Petals 

 bright pink. Filaments pink, exceeding the green styles. Fruit of 

 moderate size, black, abundantly produced. 



R. imbricatus Hort. Until lately there was but one locality 

 known near Bristol for this rare plant. In August last it was 

 found in two or three spots on the edge of Syston Common, several 

 miles from the original station in Glen Frome. All are in West 

 Gloucester. 



R. erythrinus Genev. Mentioned under U. Lindleianus in FL 

 Brist. Coal/, p. 58, as an unnamed form, some years before Mr. 

 Briggs published a description in this Journal. Tke plant is 

 frequent and abundant about Bristol, and varies little, except in the 

 amount of felt with which the panicle is clothed. The lower axillary 

 panicle branches lengthen out greatly by the time the fruit is ripe. 

 Leaves of the barren shoot are often ternate. G. In plenty by the 

 Avon under Sneyd Park, extending as far as tke Black Rock Quarry. 

 By tke " Arbutus Walk," Henbury. Abundant about Hanham. 

 Mangotsfield and Syston Commons. *S. Leigk Down. Between 

 Brislington and Keynskam. Compton Dando. 



*7u argenteus Weike. Grows plentifully in two widely separated 

 localities in Nortk Somerset, viz., in kedges at Brislington, and in 

 a lane near tke River Ckew, between Woollard and Compton Dando. 

 Altkougk closely allied to erythrinus, as pointed out by Dr. Focke, 

 there are points of difference that readily distinguish the two ; 

 notably tke kairy stem of argenteus, its wkite-felted foliage, and tke 

 constant presence of setae upon the panicle. No glands have been 

 seen on the erythrinus of this neighbourhood. Moreover, the in- 

 florescence of tke latter is subpyramidal in outline, and closer tban 

 tke long leafy cylindrical panicle of argenteus. Petals pale pink. 

 Filaments wkite, about equalling tke green styles. 



*R. pubescens W. & N. Ratker frequent in kedges at Berrow, 

 N. Somerset. Named by Mr. J. G. Baker. 



R. rusticanus x leucostachys. One busk of tkis grows on Leigk 

 Down, N. Somerset, near tke Water Company's reservoir. 



R. rusticanus x coryli/olius. A small patck on the right bank of 



the stream in the valley just below Wyck Rocks, West Gloucester. 

 Determined by Mr. Moyle Rogers. Hybrid Rubi are rare in the 

 West of England. The two above mentioned are all that have 

 been observed in the large area of tke Bristol Coal-field,
