ON THE RUBI LIST IN 'LONDON CATALOGUE.' 47 



Var. b. Immstemon (P. J. Muell.). 5 v.-c. (6, 17, 27, 38, 109). 

 [59, 88] . Still very imperfectly known by us in England. 



E. EoGERsii Linton, Joitrn. Bot. 1894, 213, 214. 5 v.-c. (8, 5, 

 27, 40, 57). I. 



R. NiTiDus W. & N. No. in Set, 3. 13 v.-c. ("Cornwall," 3, 4, 

 9, 11, 17, 22, 34, 42, 43, 48, 49, 52). [8, 14, 36, 58] . On tins 

 and on the two next plants reference should be made to Dr. Focke's 

 remarks in Journ. Bot. 1890, 100. By the var. "b. hamulosus 

 P. J. Muell." of Lond. Cat. ed. 8 (Journ. Bot. 1886, 218), I believe 

 a white-flowered form of the typical German plant to have been 

 referred to. But the plant recorded in some of the counties 

 enumerated above is much less marked than this, and therefore 

 not so easily distinguished from R. plicatns. 



R. iNTEGRiBAsis'P. J. Muell. ? No. in Set, 4. 3 v.-c. (6, 9, 11). 

 This appears to me to be most readily separable from nitidus forms, 

 as from all other true Suberecti, by the sepals externally hoary. 



E. HOLERYTHROS Focke. Ft,, nitidus Genev. Ess. Man. p. 311. 

 3 v.-c. (3, 17, 22). This is the strong handsome plant with very 

 large flowers referred to in my Essay, Journ. Bot. 1892, 110 (under 

 R. integribasis), as abundant on S.W. Surrey heaths and commons. 

 Dr. Focke took specimens from there and from Boar's Hill, Berks, 

 last summer, and has since named it as above. It may be dis- 

 tinguished from its allies, R. integribasis, R. affinis, and R. villi- 

 caidis, by the following characters : — St. striate, slightly hairy. 

 Prickles many, strong, much compressed, mostly rather declining. 

 Leaves large, 5-nate-digitate. Lts. wide-spreading, irregularly toothed, 

 very soft beneath ivith short white hairs; term, long-pethduled, nearly 

 oval -acuminate. Prickles on flowering shoot falcate. Panicle usually 

 short, with the topmost branches very crowded and few-flower ed, though 

 in luxuriant plants becoming cymose (like the lower ones). Fl. very 

 showy. Sep. mostly with long cuspidate-acuminate points, externally 

 greyish green, with felt and long hair (like the pedicels and rachis), 

 reflexed after flowering. Petals very large, oval or obovate, pinkish, 

 as ultimately are the styles and long stamens (whence Dr. Focke's 

 name). 



E. oPAcus Focke. 3 v.-c. (6, 9, 15). [3, 11, 107] . Quite Dr. 

 Focke's plant for v.-c. 6, 9, and 15. Probably the same in S. Hants 

 and E. Sutherland; but the plant locally so abundant in S. Devon 

 {Journ. Bot. 1890, 100) seems nearer to my R. afftnis var. Briggd- 

 anns, though not identical with it. Some of our other plants 

 formerly placed under R. opacus belong to R. Fioqersii (see above). 



R. AFFiNis W. & N. Journ. Bot. 1890, 101. No. in Set, 5. 

 14 v.-c. (3-6, 9-11, 14, 16, 17, 27, 34, 52, 95). [77, 88, 89] . I. 

 Formerly quite misunderstood by us in England, the plant which 

 was usually so named being R. villicaidis Koehl. var. Selmeri 

 (Lindeb.). 



Var. b. Briggsianus Eogers, Jouryi. Bot. 1894, 42. 7 v.-c. (2-5, 

 9, 49, 62). I think certainly best placed as a var. of R. afftnis, 

 though it comes near to some of the plants which Dr. Focke 

 associates with R. nitidus. 



R. cARiENSis Rip. & Genev. No. in Set, 53. 3 v.-c. (4, 5, 9).
