ROSACE AE. — PYRACANTHA 177 



Western Szech'u an: north of Tachien-lu, alt. 3000 m., July 1908 

 (No. 2i88, 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.

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 la 

 quite different.
