ULMACEAE. — PTEROCELTIS 285 
with ripe fruits); same locality, May 1907 (No. 268%; with young 
fruits); same locality, mountains, riversides, very rare, May 1901 
(Veitch Exped. No. 1875; tree 10 m. tall; with young fruits). East- 
ern Szech'uan: * Tchen-kéou-tin,” P. Farges (with # flowers and 
also with young and ripe fruits) Western Szech’uan: near 
Wa-shan, Tung River valley, roadside, alt. 600 m., September 21, 1908

Shensi: “ Lao-y-san (Zu-lu),” September 6, 1887, G. Giraldi (with 
ripe fruits). Chili: Peking, “in horto ecclesiae rossicae Pekini insti- 
tutae,” June 1847, A. Tatarinow (type, ex Maximowicz). Shantung: 
Su-yung, September 25, 1907, F. N. Meyer (large tree having a scaly 
whitish bark and small leaves); Lung-tung, September 25, 1907, F. N. 
Meyer (No. 247; sterile, leaves coarsely serrate, up to 12 cm. long 
and 7 em. wide). Kweichou: “ Gan-Chouen, bois," May 1910, J. 
Cavalerie (No. 3784, type of Ulmus Cavaleriei; with fruits). 
A very distinct genus of which Maximowicz described only the ¢ flowers and 
fruits. I add the following description of the 9 flowers from Wilson's No. 255°: 
flores 9 in axillis foliorum ramulorum brevium novellorum mense Martii v. Aprili 
singuli, pedicello distincto sparse piloso suffulti; perigonia lobis 4 liberis lanceo- 
latis viridescentibus plus minusve (praesertim apice) pilosis ovario (stigmatibus 
exclusis) vix longioribus; ovaria sessilia, elliptico-rotunda, latere compressa, in facie 
sparse pilosa, stigmatibus 2 lanceolatis plus minusve divaricatis paulo brevioribus 
coronata. 
The ripe fruits of the type of Ulmus Cavaleriei Léveillé are distinctly pilose 
upon the seed, while they are wholly glabrous in the other specimens before me. 
ther investigation is needed to decide if the form from Kweichou represents 
a distinct variety. 
As far as I have been able to observe this is everywhere a rare tree, but it is to be 
found here and there at low altitudes in western Hupeh and throughout Szech’uan. 
It is usually found near streams and is partial to rocky places in warm valleys. 
Some 5 miles above Ichang, by the side of the Yangtsze River and near the entrance 
to San-yu-tung Glen there is a fine old specimen about 16 m. tall, with a short 
gnarled trunk 5 m. in girth and much branched to form a wide-spreading crown. 
As it usually appears it is a tree from 12 to 15 em. tall with a short trunk from 1.5 
to 2.5 m. in girth, and divided near the base into several ascending and spreading 
stems which branch to form a wide-spreading flattened-round head. The bark is 
cecidi peels off in elongated flakes of very irregular shape, and is very 
c. 
Pictures of this tree will be found under Nos. 34, 368 and 469 of the collection of 
my photographs and also in my Vegetation of Western China, Nos. T T x
