A. Gray)" 1 ' 1 are undoubtedly referable to Coriaria intermedin Matsum. The 

 thirteen known species of the genua have a peculiar geographical distribution, 

 extending from the Mediterranean region to the mountains of British India. 

 China, Japan and Formosa, and from New Guinea to New Zealand. .Mexico, and 

 South America. The presence of this Formosan species in Benguet adds another 

 very characteristic species to the known northern element in the Philippine flora.

ZIZYPHUS Juss. 



Zizyphus cumingiana Merrill sp. m>v. Zizyphus aff. X. baclei DC,, Vidal, Phan. 

 Cuming. Philip. | 1885) 104. 

 A scandent shrub reaching a height of 10 in., with broadly-ovate to 

 oblong-ovate, inequilateral, nearly glabrous, 3-nerved leaves, the lateral 

 aerves branched, solitary spines and sessile or short-peduncled cymes 

 about equaling the petioles. Branches dark brown, the older ones lenti- 

 cellate, glabrous, the branchlets slender, more or less ferruginous pubes- 

 cent, the spines stout, recurved, short. Leaves submembranous. shining. 

 glabrous, or when young the nerves on both surfaces somewhat pubescent, 

 the margins obscurely crenate or dentate, the teeth often apiculate, 1 

 to (i cm. long, 2 to 3.5 cm. wide, the base rather strongly inequilateral. 

 broad, rounded, sometimes subcordate, the apex acuminate, the acumen 

 blunt, often obscurely apiculate; nerves .'!. the lateral ones scarcely 

 reaching the apex of the leaf and sending rather bold, curved-ascending 

 branches toward the margin, the lower branches often similating basal 

 aerves, so that sometimes the leaves appear to be 1 or 5-nerved; petioles 

 (> to 8 mm. long, usually somewhat pubescent. Cymes about 8 mm. 

 long, few flowered, slightly ferruginous-pubescent. Flowers greenish 

 white, about 1 mm. in diameter, the pedicels 2 to I mm. long. Calyx 

 glabrous or with very i'ow hairs outside, the lobes ovate, acute, nearly 

 2 mm. long, keeled within. Petals about L.5 mm. long, obovate-spatulate, 

 cucullate, clawed. Disk glabrous, 10-crenate. Fruit obovoid, glabrous, 

 black when dry, 1 -celled, 1-seeded, 6 to ) mm. long.
