 in. long, shining above ; petioles pubescent. Flowers minute, pubescent, in 

 axillary clusters ; the upper ones sometimes forming a short leafless, simple 

 panicle or raceme; the pedicels about a line long. Nut 2 or 3 lines in 

 diam., adherent calyx-tube reaching about the middle ; terminal wing smooth

 pressions ; margin free. Stamens 5, included in the petals or exceeding

A genus of about 50 species, scattered over the tropics and subtropics, chiefly in Asia and 

 America, a few extending to the Pacific islands and Australia. 

 Leaves glabrous above, beneath as well as the young branches with 



a dense ferruginous or grey tomentum, very rarely almost glabrous. 



Disk with 10, more or less distinct, cavities 1. Z.jujuba. 



Leaves nearly or quite glabrous. Young branches pubescent. Disk 



uniformly pubescent or glabrous 2. Z. mucroHata. 



Leaves pale, glaucous, greeu, glabrous, except when quite young. 



Branches drooping, glabrous ; bark white, shining. Disk with a 



fringe of hairs around the base of the style S. Z. Spina CAriiti. 



1. Z. jujuba, Lam. ; DC. Prod. ii. 21. A loosely branched tree or

 slightly narrowed and equal or unequal at the base, serrulate, glabrous above, 

 beneath as well as the petioles young branches and flowers with a dense, 

 short, ferruginous or nearly white tomentum, very rarely almost glabrous. 

 Stipules spinescent, one or both recurved, rarely absent. Cymes subsessile 

 or shortly pedunculate, 10-30-flowered. Disk more or less distinctly 10-

 lobes erect. Drupe spherical about 1^ in. in diam., 2- or, by abortion, 1-
