This species is well distinguished by the characters given in the key on p. 275. 
The leaves of vigorous plants usually are large and somewhat resemble in their 
shape those of C. jessoensis Koidzumi. On vigorous shoots the pubescence of the 
leaves is not only very rough on both sides, but also the shape of the leaves is often 
variable, as they are often abruptly contracted below their middle into a more or 
less distinctly caudate, mostly entire narrow-lanceolate apex; there may be every 
transition from this lyrate form to the normal shape. Such a change of shape 
occurs in the leaves of young plants in different (probably in most of the) species 
of Celtis. 
The stones of C. sinensis are more or less irregularly pitted and ribbed or some- 
times rather smooth (see Taquet’s No. 344). 
To this species seems closely related, according to the author's description, C. 
boninensis Koidzumi (in Tokyo Bot. Mag. XXVII. 183 [1913]), from the Ryukyu 
(Liukiu) Islands, Okinawa. The young branchlets are *'ferrugineo-tomentosi 
mox glabri," the leaves “ membranacea, nascentia utrinque rufo-pubescentia cito 
glabra . . . usque 14 cm. longa, 6 cm. lata; petiolis cito glabris 10-5 mm. longis." 
The fruit is “ carnea 6-7 mm. in diametro; pedicellis 10-14 mm. longis solitariis 
v. geminis, endocarpio laeve.” The main differences from C. sinensis seem to be 
the large leaves and smooth stones. The only specimen before me which some- 
what agrees with the description is Jack's specimen from Chinnampo, but neither 
the branchlets nor the petioles are glabrous, and there are no fruits.
