Arbor ad 17 m. alta, trunco cortice levi pro genere normali obtecto; 
ramuli hornotini dense breviter villosuli v. pro parte glabri, brunnes- 
centes, lenticellis satis magnis discoloribus conspersi, annotini cinereo- 
rubiginosi, glabri, vetustiores cinerascentes. Folia satis parva, adulta 
firma, ovato-oblonga, basi vix v. paulo inaequali subrotunda v. late 
cuneata, apicem versus satis sensim acuminata, interdum fere brevi- 
ter caudata, supra satis viridia, tantum in costa impressa nervisque 
plus minusve sparse pilosula, subtus in sicco cinerascentia (v. paulo 
brunnescentia), saepissime tantum in axillis nervorum lateralium utrin- 
secus 7-9 (imo apice excepto) paulo prominentium albo-barbata, 
ceterum glabra v. pilis sparsis difficile recognoscendis praedita, mar- 
gine regulariter et breviter crenato-serrata serraturis non v. vix 
apiculatis, 1.5-4.8 em. longa et 0.8-2.3 cm. lata; petioli 1-4 mm. 
longi, villosuli. Flores ignoti. Fructus maturi singuli, axillares, 
irregulariter obovato-rhomboidei, glabri (v. sparse pilosuli), circiter 
5 mm. longi et crassi, basi perigonio 5 lobato persistente suffulti, apice 
stigmatibus 2 incurvis coronati; pedicelli brevissimi, pilosi. 
Western Hupeh: Hsing-shan Hsien, roadside, alt. 900 m., Octo- 
ber 1907 (No. 2699, type; tree 7-17 m. tall, girth 0.35-1.8 m.; with 
ripe fruits and bark); same locality, etc., July 1907 (No. 2699*; with 
unripe fruits). Northern Shensi: “ Kian-san," August 8, 1897, 
J. Giraldi (with fruits); * Lao-y-san," 1897, J. Giraldi (sterile; leaves 
up to 6.3 em. long and 2.5 em. wide, petioles up to 8 mm. long). 
Chekiang: Ningpo, E. Faber (mature leaves as in the type, but 
loosely pubescent beneath). Kiangsu; Shanghai, E. Faber (younger 
leaves with a soft pubescence beneath, young fruits hairy). 
The specimens enumerated above agree well with each other in their small leaves 
with a short crenate serration. The pubescence of Faber's specimens is, so far as I 
can see, due to a younger condition of the leaves. In F. N. Meyer's specimens 
mentioned below the leaves are mostly larger and have a distinctly apiculate ser- 
ration, their texture and nervation being somewhat different too. There 15 4 
sterile specimen collected by him in Kiangsu, Spirit Valley, near Nanking, June 
4, 1915 (No. 1444; at edges of forest in rich soil), the leaves of which are up to 
9.5 em. long and 4.5 em. wide. They are rough above and bear a distinct pu-
