300 WILSOX EXPEDITION TO CHINA 



SPECIES VARIETATESQUE POMOIDEARUM IMPERFECTE NOTAE 



ASIAE ORIENTALIS. 



Of the following recently described species and varieties of Pyrus and Sorhus, 

 I have seen no specimens, and as their descriptions are not sufficient for definite 

 determination they could not be referred to their proper position. 



Pyrus AriQj var, Silvestrii Pampanini in Nuov. Giorn. Bot. Ital, n. ser. XVII. 

 290 (1910). 



Pyrus Bodinieri L^veill^, Fl Kouy-Tckeou, 350 (1915). 



Pyrus hrunnea L^veille in Fedde, Rep. Spec. Nov. X. 377 (1912). 



Pyrus Cavaleriei Leveille, 1. c. XI. 67 (1912). 



Pyrus Esquirolii Leveille, 1, c. Xll. 189 (1913). 



Pyrus Feddei Leveille, 1. c. XII. 189 (1913). 



Pyrus ferruginea Koidzumi in Tokyo BoL Mag. XXIX. 158 (not Hooker f.) 

 (1915). 

 This is probably only a cultivated form or possibly hybrid of P. serotina 

 Rehder escaped and naturalized, though Koidzumi compares it with P. avoided 

 Rehder. Neither the flowers nor the mature fruits were known to the author. 



Pyrus hupehensis Pampanini in Nuav. Giorn. BoL Ital n. ser. XVII. 291 (1910), 



According to the description this species would seem near to or identical with 



P. serrulata Rehder, but Pampanini describes the styles as connate and villose- 



tomentose at the base, which removes the species from the genus Pyrus altogether. 



Pyrus Koehnei Leveille in Fedde, Rep, Spec. Nov. X. 378 (non Schneider) (1912) . 



Pyrus Mairei Leveille, 1. c. XII. 189 (1913). 



Pyrus rnohpoensis Leveille, 1. c. VII. 200 (1909). 



Pyrvs sinensis, var, Maximowicziana Leveille, 1. c. X. 377 (1912). 



Pyrus spectabilisy var. albescens L6veille, 1. c. X. 377 (1912). 



Pyrus Taquetii Leveille, I. c. VII. 199 (1909). 



Pyrus Vaniotii L6veillc, 1. c. VII. 200 (1909). 



Sorbus Aria, var. Mairei Leveille, 1. c. XIII. 341 (1914). 



Subfam. ROSOIDEAE.
