Same year. In 1913 Koehne (l.c.) described this Wilson number as Sorbus munda f. subarachnoidea, and under this name the plant has become known in cultivation in this country, despite the fact that in 1917, only four years after it was published, S. munda had been reduced to another species, S. Prattii Koehne. Koehne referred to S. munda specimens collected by Wilson in Szechwan, under two numbers, designating both of them as forms to which he gave names, namely f. tatsienensis (no. 991, from Tachien-lu, woodlands at 2300-3300 m. September 1908) and, as already mentioned, f. subarachnoidea (no. 4323, from Pan-lan-shan, west of Kuan Hsien-i.e., about 160 km. N.E. of Tachien-lu-at 2600-3000 m., October, 1910). The f. tatsienensis was distinguished by having leaves with 21-25 leaflets, glabrous or hairy only along the midrib on the lower side, whereas.
