68 ON CANARIAN AND MABEIRAN 



radicalibus reniformibus incisis late parciusque vel remote grossicre- 



natis, caulinis 3-5-partitis, sumrais sessilibus simplicibus lanceolatis 



integerrimis ; fl. sparsis remotis distinctis, pedicellis gracilibus elon- 



gatis; sep. patentibus; spicis cylindrico-oblongis ; ach. plerumque 



sparsim hispidis.

 "K. Teneriffce, Pers. Ench. 2, 103/' DC. Webb 1. c; utroque ad var. 



suam /3 (omnino diversam) referente. 

 Hab. In Ins. Canariensibus "in rupestribus graminosis regionis syl- 



vaticse Teneriffse, Canarise et Palmse, etc.," Webb. 



From Canarian specimens in the Banksian and Hookerian Herbaria, 

 from Masson, Webb, Bourgeau, etc. 



Root small, fascicled, with slender, tuberous divisions, as in R. Cre- 

 ticus, L. Stem 6-18 inches high, erect and branched, but scarcely 

 corymbose, few-flowered, the whole habit altogether more slender than 

 in R. grandifolim, and more like that of R, Creticus, L. Lower leaves 



dark green," Webb, generally spotted with clear, defined, small, an- 

 gular, black specks or dashes, but sometimes quite immaculate, broader 

 than long, not above 3 or 4 inches in diameter, and though of thinner 

 texture, yet in shape as well as size and crenation much resembling 

 those of R. Creticus, L., differing however in their distinctly bulbous 

 hairs, most conspicuous on their upper surface. Petioles clothed, like 

 the stem and pedicels, with spreading hairs, which are rather callous- 

 swollen than distinctly bulbous at the base. Plowers not corymbose, 

 but few and scattered, as in R. Creticus, L., larger however than in that 

 species (i. e. 1-1 ^ inch in diameter) with much more slender, elongated 

 pedicels. Spike always distinctly oblong, viz. 6-7 lines long (N.B. 

 Webb, by a misprint or slip in his description, has 6 poll, for 6 lin.), 

 and 2-4 lines broad. Achsenia, especially the lower, almost always 

 sprinkled with short, thick, glandular hairs, but occasionally in robuster 

 plants almost or quite smooth. 



Webb having already well and fully pointed out the distinctive cha- 

 racters of R. cortusafolius, compared with R. Creticus, I shall confine 

 myself to those by which it is to be distinguished from its less near 

 ally R. grandifoUm.
