Western Hupeh: Fang Hsien, woods, alt. 1300-2000 m., June 
1907 (No. 70, belongs partly here, partly to P. pilosiuscula, 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 colleeting 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 Zoólogy 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. 
1. Exemplaria fructifera. Frutex 1.3-2.6 m. altus; rami hornotini 
glabri, vetustiores ochraceo-cani; gemmae 1.5 mm. longae. Stipulae 
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. subsimplieibus, 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 tantum crasso-glandulosis; 
pedicelli solitarii, 13-21 mm. longi. Drupa 10:8 mm., nigra; putamen 
8:5:4 mm., obsolete sulcatum.
