var. pseudossiori in their broader and shorter, elliptic to obovate, abruptly 

 acuminate leaves but agree in serration and texture with specimens of 

 typical leaf shape; no. 1809 has rather membranous leaves and may 

 possibly belong to P. Partus.

The following three apparently distinct forms of Prunus of the Hers 

 collection have remained unidentified owing to the incomplete material: 



Prunus spec, from Honan: Sung hsien, San kuan miao, J. Hers, no. 

 548, May 24, 1919 (with young fruits). Apparently related to P. triloba, 

 but the bark of one-year-old branches is light yellow and exfoliates in 



flakes and strips. 



Prunus spec, from Shensi: Lung chow, Kuan shan, alt. 2000 m., J. 

 Hers, no. 2358, July 3, 1922 (sterile). Related to P. lobulata Koehne, 

 but the leaves are rather short-petioled and the stipules more leaf-like and 



less deeply divided. 



Prunus spec, from Honan: Sung hsien, Shih tze miao, J. Hers, nos. 484 

 and 1273, May 26 and September 25, 1919 (sterile). Similar to P. Padus 

 var. pubescens, but the leaves are larger, finely serrulate and glaucous 

 beneath.
