Hab. Fuente la Kosa, April, 1909 (no. 56). 



A very distinct species, most nearly allied to B. trachypodium, 

 but entirely different in its habit, the absence of the glossiness 

 that is a marked character of that plant, the turgid subjulaceous 

 branches, the markedly recurved leaf-margins, less sharply toothed 

 leaves, and small capsules, which are abundantly produced. The 

 apex of the nerve usually ends in one to three serrulations, showing 

 as short spinulose projections from the back of the leaf, as is 

 frequently the case in B. trachypodium and B. Starkei.

 It is on record for La Palma, but I have not seen any record from 

 Teneriffe. — E. circinatum (Brid.) B. & S. Ladera de Guimar 

 (no. 48). — E. meridionale (Schp.) De Not., forma. Barranco del 

 Rio (no. 44), c. fr. A robust plant with strongly striate, rigid 

 leaves, more like a small form of E. striatum. I take it to be the 

 E. canariense (Hampe & C. M.) referred to by Ren. & Card, in 

 Bull, de l'H6rb. Boissier, ii. 438 (1902).
