extending from the iMediterranean region to the mountains of Jfritish India, 
China, Japan and Formosa, and from New Guinea to New /ealand, Mexico, and

Zizyphus cumingiana iMerrill sp. nov. Zizyphus atf. /. harlei DC., Vidal, Phan. 
Chiming. I’liilip. (1885) 104. 
A scandent slinilj reaching a height of 10 in., with broadly-ovate to 
oblong-ovate, inet|iii lateral, nearly glabrous, o-nerved leaves, the lateral 
nerves branched, solitaiy spines and sessile or short-peduncled cymes 
about equaling the })etioles. Branches dark brown, the older ones lenti- 
cellate, gialirous, the liranchlets slender, more or less ferruginous pubes- 
cent, the spines stout, recurved, short. Leaves sulmiemliranous, shining, 
glabrous, or when young the nerves on liofh surfaces somewhat pubescent, 
the margins obscurely eremite or dentate, the teeth often apiculate, 4 
to () cm. long, 2 to 3.5 cm. wide, the base rather strongly inetpiilateral, 
broad, rounded, sometimes suheordate, the apex acuminate, the acumen 
blunt, often obscurely apiculate; nerves 3, the lateral ones scarcely 
reaching the apex of the leaf and sending rather hold, curved-ascending 
branches toward the margin, the lower branches often similating basal 
nerves, so that sometimes the leaves appear to lie 4 or 5-nerved; petioles 
G to 8 mm. long, usually somewhat }»ul)escent. Cymes about 8 mm. 
long, few howered, slightly ferruginous-pubescent. Blowers greenish 
white, about 4 mm. in diameter, the jiedicels 2 to 4 mm. long. Gbilvx 
glabrous or with very few hairs outside, the lolies ovate, acute, nearly 
2 mm. long, keeled within. Petals aliout 1.5 mm. long, oliovate-spatulate, 
cucullate, clawed. Disk glabrous, lO-crenate. Fruit oliovoid, glabrous, 
l)lack when dry, 1-celled, 1-seeded, G to 7 mm. long.
