ROSACEAE. — PYRACANTHA 177 
Western Szech’uan: north of Tachien-lu, alt. 3000 m., July 1908 
(No. 2188, growing appressed to rocks, or hanging over cliffs, flowers 
white). 
This variety is well-marked; its small leaves are pubescent on both surfaces 
and the margins are very little reflexed. 
Here may be added the description of a new species of which neither the ripe 
fruits nor the petals are known and which therefore cannot with absolute certainty 
be referred to one of the sections.

Frutex 60-75 em. altus ramosissimus ramis brevibus plus minus tortuosis; ramuli 
hornotini annotinique breviter villoso-tomentosi, vetustiores obscure grisei, in- 
novationes plurimi brevissimi internodiis minimis v. fere nullis, inde rami ob 
bases petiolorum persistentes dense verrucosi. Folia subcoriacea, partim persis-

villosae, 1-1.5 mm. longae. Flores terminales, subsessiles, plerumque solitarii,

Western Szech'uan: without locality, exposed rocks, alt. 1800 m., July 1903, 
(Veitch Exped. No. 3513). 
This species, which in its habit and general appearance is unlike any other 
Species, most resembles C. microphylla, var. vellaea Rehder & Wilson, but the leaves 
are larger and longer and much more hairy on the upper surface and the habit is 
quite different,
