The writer has seen only herbarium specimens of this plant and has taken the description given from European texts. According to Schneider the species has been divided into two varieties by the Italian botanists. _Prunus cocomilia typica_ having oblong-ovate fruit and _Prunus cocomilia brutia_ having round fruit. Schneider holds also that _Prunus pseudoarmeniaca_ Heldr. and Sart.[82] from Epirus and Thessaly is a variety of _Prunus cocomilia_ differing chiefly in having more pointed leaves and smaller oblong-roundish red plums. The same author puts in this species still another plum, a hairy-leaved form from Thessaly which he calls _Prunus cocomilia puberula_. He places here also _Prunus ursina_ Kotschy[83] which differs only in minor respects from the species, chiefly in having violet-red fruit though Boissier[84] mentions a yellow-fruited plum which he calls _Prunus ursina flava_. The last named plums come from Lebanon and North Syria. =6.= =PRUNUS CERASIFERA= Ehrhart[85] [Illustration: _PRUNUS CERASIFERA_] =1.= Ehrhart _Beitr. Nat._ =4=:17. 1789. =2.= Hooker _Brit.

Tree small or a tree-like shrub, seldom exceeding twenty-five feet in height; branches upright, slender, twiggy, unarmed or sometimes thorny; branchlets soon glabrous, becoming yellow or chestnut-brown; lenticels few, small, orange in color, raised. Winter-buds small, obtuse, short-pointed, pale reddish-brown; leaves small, short-ovate, apex acute, base cuneate or rounded, thin, membranaceous, texture firm, light green, nearly glabrous on both surfaces at maturity, though hairy along the rib on the lower surface, margins finely and closely serrate; petiole one-half or three-quarters of an inch long, slender, usually glabrous, glandless. Flowers large, three-quarters of an inch in diameter, expanding very early or mostly with the leaves; calyx-lobes lanceolate, glandular, reflexed; petals white, sometimes with a blush, ovate-oblong or orbicular, the base contracted into a claw; borne singly, sometimes in pairs, in cymes on long, slender, glabrous peduncles. Fruit small, one-half inch or a little more in diameter, globular or depressed-globular, cherry-like, red or yellow; skin thin and tender; flesh soft, juicy, sweet and rather pleasantly flavored; stone oval, short-pointed at both ends, somewhat turgid, ridged on one suture and grooved on the other.
