cymes scarcely longer than the petioles: ovary 2-celled: styles 2, nearly

_ 508. (3) Z. aylopyra (Willd.:) arboreous: stipulary prickles solitary or 
in pairs (in a poor soil), or wanting: leaves broadly elliptical or orbicular, 
obtuse, slightly cordate at the base, serrulated ; under side pale, softly pu- 
bescent, finely reticulated ; upper when young pubescent: cymes short:

This species may always be readily recognised by the leaves pale and soft 
beneath, and the 3-celled ovary: on which account we are inclined to add 
to the above synonyms Z. ruminata, Ham. ! in Wall. L. n. 4236. 
509. (4) Z. Jujuba (Lam. :) arboreous : stipulary prickles short, in pairs OF

tawny (when dried) tomentum: cymes sessile or very shortly pedunclec : 
ovary 2-celled : styles 2, united to the middle: drupe spherical: nut rugose; 
hard and thick, 2-celled.— Lam. ene. meth. 3. p. 3185 DC. prod. 2. p: 21;
