Western Hupeh: Fang Hsien, woods, alt. 1300-2000 m., June 

 1907 (No. 70, belongs partly here, partly to P. pilosinscula, var. bar- 

 bata Koehne); thickets, Patung Hsien, alt. 1000-1600 m., June 1907 

 (No. 45). 



At the request of Mr. Wilson this species is named in compliment to Walter 

 Reeves Zappey, who was associated with Wilson during 1907-1909 for the purpose 

 of collecting Birds and Mammals. His whole collection of more than four thou- 

 sand specimens has been presented by Mr. John E. Thayer to the Museum of 

 Comparative Zoology of Harvard University. 



The fruits of the two Nos. seem to be somewhat different. In No. 70, too, the 

 leaves are smaller (up to 4.2:4 m.) and in No. 45 larger (up to 8:35). From P. 

 pleuroptera Koehne this species is distinguished particularly by the ovoid not glo- 

 bular stones and by the midrib not being winged beneath. 



Here may be added two doubtful forms under the following name: 



Prunus Zappeyana, var. subsimplex Koehne, n. var.

 6-7 mm. longae; petioli 5-7 mm. longi, glabri v. superne parce villosi; 

 lamina ovato-oblonga, brevius serrata, dentibus maxima ex parte 

 simplicibus v. subsimplicibus, acuminatis, glandula minutissima v. 

 nulla terminatis, supra in costa villosa, ceterum parcissime, praesertim 

 versus marginem, pilis conspersa, subtus glabra v. axilloso-barbulata 

 et in nervis venisque parce hirtella, subcoriacea, nervis utrinsecus 6-10, 

 subtus multo pallidior. Bracteae 4-7, rotundatae, 3-9 mm. longae, 

 serratae dentibus eglandulosis v. infimis tan turn crasso-glandulosis;

 8:5:4 mm., obsolete sulcatum.
