=16.= =PRUNUS MITIS= Beadle =1.= Beadle _Bilt. Bot. Stud._ =1=:162. 1902. =2.= Britton and Brown _N. Am. Trees_ 489. 1908. Tree small, maximum height twenty-five feet; bark dark brown or reddish-gray; branches spreading or ascending, usually unarmed; branchlets glabrous, glaucous; leaves thin, elliptic, oblong-lanceolate, sometimes ovate or obovate, apex acute or acuminate, base narrow or rounded, margin sharply serrate; petioles less than one-half inch, densely pubescent, with two glands at or on the base of the leaf; upper surface bright green, finely pubescent, lower surface paler, also pubescent and with a prominent midrib and veins. Flowers of medium size, appearing before the leaves; borne in sub-sessile, two to six-flowered umbels; calyx-tube obconic, smooth, its lobes triangular, pubescent on the outer and velvety on the inner surface; petals white, obovate, clawed; pedicels slender, smooth, three-quarters inch long. Fruit ripening in mid-summer; over one-half inch in length, oblong, dark purple with a heavy bloom; stone ovoid or oval, flattened, nearly one-half inch long, pointed at both ends especially at the apex, and crested on one edge. _Prunus mitis_ is a newly named species from Alabama, common in dry soils in the regions where it is found wild. The species has many characters in common with _Prunus umbellata_ to which it is so closely related that it is difficult to distinguish the two in herbarium specimens. Although nothing is yet known of its horticultural possibilities the apparent relationship does not indicate much value in the plum for the cultivator. =17.= =PRUNUS TARDA= Sargent =1.= Sargent _Bot. Gaz._ =33=:108. 1902. =2.= Ibid. _Sil. N. Am._ =13=:23, Pl. 632. 1902. Tree from twenty to twenty-five feet in height; trunk tall, eighteen or twenty inches in diameter; bark light brown, reddish, thick, with flat ridges and plate-like scales; branches spreading, forming an open symmetrical head; branchlets slender, at first light green and tomentose becoming glabrous, light brownish and lustrous, and the second year much darker; lenticels small, dark, scattered. Leaves oblong to obovate, apex acute and sharp-pointed, base rounded or cuneate, margin finely serrate with incurved, glandular teeth, in texture thick and firm; upper surface glabrous, dark yellow-green, lower surface pubescent, pale green; petioles stout, tomentose or pubescent, short, eglandular or with two stalked, dark glands at the apex; stipules acicular, often bright red, small.
