300 key to British bubi. 



base. Pan. long, rather narrow, and many-flowered, chiefly ultra- 

 axillary ; branches erect-patent; rachis villous, felted, with many 

 stalked glands about equalling the hairs, and subulate strongly 

 declining prickles, which are hardly distinguishable from the acicles 

 in the upper part, but are stronger lower down. FL star-like. 

 Sep. glandular, aciculate, ovate-acuminate, reflexed. Pet. elliptic, 

 and narrowed below with us (sometimes orbicular in Germany), 

 purplish at first, then white. Stam. white or pinkish, far exceeding 

 the greenish red- based styles. Heaths, hedges, and waste places. 



One of our most easily recognised species, usually keeping very 

 distinct in S. Engl., where the pale narrow foliage and very marked 

 armature separate it from all its allies ; but in N. Engl, it generally 

 has darker leaves and more unequal prickles, especially on the pan. 



Lees' R. Leightoni seems hardly separable, even as a var. (v. Brit. 

 Rub. p. 196). 



b. R. Bloxamianus Colem. Joum. Bot. 1887, pp. 102, 103; 

 B. E. C. Rep. 1889, pp. 255, 256. — St. glabrous, or nearly so; 



large prickles patent ; stalked glands very crowded, with a few stout- 

 based acicles or pricklets intermixed, all short. L. 5-nate and 3-nate, 

 hairy on veins, but rarely felted beneath. Term. It. round! 'y -obovate- 

 cuspidate. Pan. short, compact. Pet. white. Seems to make some 

 approach towards R. scaber. (Derb., Leic, Warw.). 



c. R. sertijiorus P. J. Muell. ? — St. subglabrous, very like that 

 of R. radula, but with broad-based deflexed prickles, and rather 

 more crowded acicles and stalked glands. L. greyer-felted, or more 

 frequently only pale green and softly hairy beneath. Lts. uniformly 

 narrow, tapering very gradually from near the acuminate point to the 

 narrow base, with shallower larger mucronate teeth. Pan. with patent 

 hairs mostly exceeding the many stalked glands; branches more 

 crowded above, and nearly patent, laxer below, with the Its. of the 

 3-nate 1. narrowed to their base even more remarkably than in the 

 st.-l. Pet. smaller, obovate, bright pink within, externally whitish. 

 Stam. pink, exceeding green styles. It is not without hesitation 

 that I place the Rev. A. Ley's Heref. plant here (v. B. E. C. Rep. 

 1890, p. 293). When fresh, as I saw it in Riggs Wood, Sellack, in 

 Aug. 1891 and 1892, it looks just intermediate between R. radula 

 and R. fuscus. 



61. E. Newbouldii Bab. Joum. Bot. 1887, pp. 20, 21 (R. radula 

 y. denticulatw Bab. Man. ; Brit. Hub.). — " St. slightly arching, 

 angular upwards, subglabrous. Prickles unequal, long, slender, 

 conical, patent, from a long compressed base, much exceeding the 

 many short aciculi and setae. L. 5-nate or 3-nate. Lts. very 'finely 

 but doubly dentate, green, and not felted beneath; term, broadly 



quadrangular- obovate, cuspidate, subcordate below. Pan. long, 

 its ultra-axillary branches many corymbose patent, its lower 

 branches racemose, falling short of 1., its prickles long, slender, 

 declining. Sep. ovate-attenuate, aciculate, setose, loosely reflexed ; 

 pet. pale pink ; stam. greenish white, exceeding the (pink ?) styles." 

 Loxley, nr. Sheffield. Mellis, Suffolk. Unknown to me from these 

 stations ; but I have received from Capt. A. H. Wolley Dod beautiful 

 specimens of what appears to be this species, gathered by him 

 abundantly near Malpas, Cheshire.
