Carya cathayensis Sargent, n. sp. 
Arbor 12-20-metralis, trunco 30-60 cm. diam.; cortex laevigatus, griseus; 
ramuli tenues, novelli squamis luteo-aurantiacis obtecti, demum puberuli et sparse 
lepidoti, annotini purpureo-grisei, versus apicem puberuli, lenticellis parvis in- 
structi. Folia 5~-7-foliolata, petiolo incluso 20-30 cm. longa; petioli et rhaches 
juniora puberula, sparse squamis obtecta; foliola breviter petiolulata, lanceolata v. 
obovato-lanceolata, interdum leviter falcata, acuminata, basi attenuata, cuneata v. 
rotundata, simpliciter serrata, margine ciliata, 10-14 cm. longa, 3.5-5 cm. lata, 
Juniora subtus dense squamis luteo-aurantiacis vestita, demum sparse lepidota, 
costa media pilosa excepta glabra, pallide luteo-aurantiaca. Flores ignoti. Fructus 
juvenilis obovoideus, basi constrictus, 4-costatus costis alatis, dense squamis luteo- 
aurantiacis obtectus; exocarpium maturum 2.5-3 mm. crassum, sparse lepidotum; 
nux ovoidea v. ovalis, subcylindrica, leviter compressa, basi rotundata, apice acuta, 
mucronulata, obscure 4-angulata, 2-2.5 cm. longa, 1.5-2 em. diam.; endocarpium 
2.5-3 mm. crassum; cotyledones apice profunde lobatae. 
Chekiang: mountains round Changhua Hsien, 70 miles west of Hangchou, at 
an elevation of about 130-400 m. above the sea-level, July 8-12, 1915 (with old 
nuts picked up from the ground), (near Yi-tsun, No. 1521) F. N. Meyer. : 
Without buds it is impossible to be sure of the section of the genus to which 
species belongs, but in spite of the few leaffets, the comparatively thick husk 
of the fruit, the thick shell of the nut and the deeply lobed cotyledons, I believe 
that it belongs to the Apocarya C. De Candolle which is distinguished by the val- 
vate scales of the bud, and that it is most closely related to C. myristiciformis 
Nuttall. This species, unlike the other American species of this section, has 
usually 7 to 9 but occasionally 5 leaflets. Like C. cathayensis, it has obovoid con- 
spicuously winged young fruit covered with yellow scales, a thick-shelled elliptic 
nut and deeply lobed cotyledons. That is, in these two species are found characters 
which connect Eucarya and A pocarya, which without these intermediate forms might 
be considered distinct genera. 
_ Since the finding in China of a species of Liriodendron and of Sassafras, pre- 
viously believed to be monotypic genera of eastern North America, no addition 
to our knowledge of the distribution of the trees of the northern hemisphere is so 
"portant and interesting as Mr. Meyer’s discovery of a representative of the 
tapes Carya ned Asia, for it has always been supposed that this genus e sore

Meyer's attention was first drawn to this tree by finding the nuts offered for 
sale 9n à fruit-stand in the city of Hanchou. In writing of his discovery he says, 
. The upper surface of the leaves is of a soft green color, while the under surface

gag reddish brown blotch of color in the midst of the ordinary green vegeta- 
clan. The nuts are collected for sale; they are eaten as a sweetmeat, and a fine 
car Yellow oil is extracted from them and used in fancy pastry. The wood is 
and strong and is used for tool-handles. The trees are more or less pro- 
not (17/2 sinensis Dode (in Bull. Soc. Dendr. France, 1912, 39, fig.) is certainly 
Mr pid and, judging by the figure of the fruit, is probably Aleurites triloba

or the oil contained in the cotyledons.
