KEY TO BRITISH RUBI 



and st. Sep. acuminate, often leaf-pointed, strongly reflexed, 

 ashy-felted. Pet. large, narrowed to base, white or faintly pinkish. 

 Whole plant remarkably pale. Allied to R. macrophyllus and jR. villi- 

 caul is, but readily distinguished from both. 



Widely distributed in S.W. Engl, (as far E. as I. of Wight), 

 though apparently somewhat thinly, except in Dev., where it is 

 abundant, extending (unlike most Kubi) even to the middle of 

 Dartmoor. 



37. R. Questierii Lefv. & Muell. ; Genevier, Essai Monoyraphie, 

 pp. 182-184 (1869). — St. angular, glabrescent, greenish. Prickles 

 strong, straight, declining or slightly falcate from dilated base. L. 

 digitate or subpedate-quinate, green on both sides, paler and with 

 close pressed hairs beneath. Lts. oval- acuminate ; the lateral 

 narrowed to their base, the term, round-based or subcordate. 

 Pan. narrowly pyramidal, long, compound, leafy, slightly hairy and 

 felted, with some stalked (/lands, and falcate or declining prickles and 

 2 or 3 long oval-lanceolate very acuminate folia ceous bracts, which 

 often exceed the pan. Cal. and ped. white felted. Sep. oval, with long 

 acuminate points, glandular. Pet. rose-coloured, oval, narrowed 

 below. Stam. white, exceeding the "salmon or rose-coloured styles.'" 

 Unknown to me. 



This description, derived from the longer one in Genevier's 

 Essai, is inserted here on account of Dr. Focke's statement (quoted 

 in the Hot. E.vch Club Import for 1888, p. 206), "I have . . . seen 

 the true It. Questierii from different places in S. Engl." 



38. Pt. Sprengelii Weihe. — St. prostrate or very slightly arching, 

 much branched, roundish, hairy. Prickles many, scattered, falcate 

 or declining from broad base; often with a few stalked glands and 

 acicles intermixed. L. mostly 3-nate, but becoming 5-nate-pedate 

 or subquinate in rich soil, and then often associated with stouter and 

 more aciculate and glandular stem. Lts. coarsely and irreyularly 

 serrate-dentate, thin, green on both sides, hairy on veins beneath; 



term, lony, narrowly elliptic-acuminate, somewhat narrowed to the 

 rounded or subcordate base. Pan. short, lax and diffuse, hairy, 

 felted ; the lower branches distant, erect-patent, corymbose, often 

 forming secondary panicles ; the upper branches patent or divaricate, 

 1-3-flowered or subumbellate, with lony slender subequal ped., weak 

 declining or falcate prickles, and usually some stalked glands. 

 PI. rather small. Sep* externally grey-green, ovate-acuminate,

Pet. 



narrow, obovate, acute, usually bright pink. Pinkish fil." almost 

 equalling greenish styles. Woods and heaths. 



A very distinct and widely-spread species, hardly falling into 

 place ffi any of our groups, but put here provisionally, as by Dr. 

 -bocke in his paper in Jmini. Pot., 1890. Dr. Salter's It Borreri 

 (authentic and thoroughly good specimens of which are preserved 

 m the Borrer Herbarium at Kew) I am disposed to place in the 

 next group (No. 48). It is locally abundant in S. Engl., and 

 readily distinguishable from the strong Hprengslii form which has 

 so otten borne the name.
