? Kansu: "Kumbum" (ex Kanitz, 1. c). 



This species seems rather variable in the shape and size of the leaflets; 

 no. 2715 from Shansi has narrow-lanceolate long-acuminate leaflets 

 4-8 cm. long, while in the specimens from Honan the leaflets are generally 

 narrow-oblong, acute, scarcely acuminate and 2-4 cm. long. I have 

 doubtfully referred to this species the plant from northwestern Kansu 

 determined by Kanitz as Pirus Aucuparia as it is more likely to be identical 

 with this northern species than with the more southern S. hupehensis 

 found in Kansu south of the Tsin ling shan range.

In some specimens as in Meyer's no. 1241 and in no. 2010 from Shansi 

 the leaflets are glabrous or nearly so and mostly entire below the middle 

 and the stipules are wanting on two of the three fruiting branches seen.
