ROSACEAE. — PYRUS 265 



Pyrus variolosa Wallich, Cat. No. 680 (nomen nudum) (1828). — G. Don, 



Gen. Syst. II. Q22 (1832). 

 Pyrus verrucuhsa Bertoloni in Mem. Accad. Set. Bolognaj ser. 2, IV. 312 



(Piante As. II.) (1864). 

 Pyrus heterophylla Hort. ex Decaisne, Jard. Fruit. I. 328, sub. t. 7 (pro 



synon.) (1872). 

 Pyrus nepalensis Herb. Hamilt. et Hort. ex Hooker f., Fl. Brit. Ind. 1\, 374 



(pro synon.) (1879). 



Western Szech'uan: Ching-chi Hsien, alt. 1500 m., October 

 1908 (No. 1335); same locality, open countrj^ alt. 2600 m., October 

 1910 (No. 4132). Yunnan: Mengtsze, alt. 1400-1500 m., A. Henry 

 (Nos. 10035, lOOSS''). Himalaya: Kashmir to Bhutan. Assam: 

 Khasia mountains, Ava (ex Hooker f.). 



This species is not mentioned by Hemsley in his Index Florae Sinensis, though 

 Hooker f. in 1879 includes Yunnan in the range of the species. Wilson's No. 

 1335 which is in ripe fruit agrees well with typical P. paskia and the young plants 

 raised at the Arnold Arboretum from seeds of that number show exactly the kind 

 of finely and sharply serrate mostly deeply lobed leaves, figured by Decaisne as 

 the form occurring on suckers. No. 4132 differs in its much shorter and tomentose 

 pedicels, only about 1.5 cm. long, and in the generally broader leaves mostly sub- 

 cordate at the base; some of the fruits show a persistent calyx. Whether this is a 

 variety of this species or a distinct species may be decided when the plants in cul- 

 tivation flower and fruit. 



Here may be added a note on a variety of this species collected by A. Henry 

 in Yunnan. 



Pyras pashia, var. kumaoni Stapf in Bat. Mag. CXXXV. t. 8256 (1909).—

Pyrus Kumaoni Decaisne, Jard. Fruit. 1. 328, sub. t. 7 (1872). — Hooker f., 

 Fl. Brit. Ind. 11. 374 (1879). — Schneider, III Handb. Lauhholzk. I. 665 

 (1906). 



Pyrus Wilhelmii Schneider, III. Handb. Laubholzk. I. 665, fig. 363 n (1906); 

 in Fedde, Rep. Spec. Nov. III. 120 (1907). 



Yunnan: Mengtsze, mountain woods, alt. 1600 m., A. Henry (No. 10035*, 

 type of P. Wilhelmii); same locality, alt. 1400 m., A. Henry (No. 10035^). 

 Himalaya : Kashmir to Kumaon (ex Hooker f.). 



This variety differs from the type in its glabrous or nearly glabrous inflorescence 

 and leaves and in the ovate, broader and often obtuse calyx-lobes. I am unable to 

 separate P, Wilhelmii specifically from this variety. Broadly ovate leaves occur 

 also in P. pashia, and the statement that P. Wilhelmii has only 3 styles is not borne 

 out by the specimen in the herbarium of the Arnold Arboretum, which represents 

 Henry's No. 10035% on which P. Wilhelmii is based, as the number of styles varies 

 in that specimen from 3 to 5. 



Pampanini describes (in Nuov. Giom. Bot. Hal. n. ser. XVII. 291 [1910]) P. 

 hupehensis as a new species allied to P. pashia and very similar in general appear- 

 ance to P. communis, but as he states that the three styles are connate at the baae 

 and villose- tomentose, this plant cannot belong to the genus Pyrus, if his statement 

 is correct,
