Burbank was produced from a plum pit sent to Luther Burbank[207] by a Japanese agent in 1883.[208] The fruit of this variety proved to be very superior and Mr. Burbank sent specimens of it to the Division of Pomology, United States Department of Agriculture in 1887, where it was named in honor of the introducer. Wassu, introduced by J. L. Normand, and the Russian plum, 20 M, sent out by Professor J. L. Budd proved to be indistinguishable from the Burbank as tested by Bailey, but Kerr[209] thinks the Wassu is a distinct variety. The American Pomological Society added Burbank to the fruit list in its catalog in 1897. Tree large, vigorous, distinguished by its low, sprawling habit and flat open top, unusually hardy for a Japanese variety, very productive, healthy; branches somewhat roughish, dark ash-gray, thickly covered with fruit-spurs, with few, large, raised lenticels; branchlets medium in thickness and length, with short internodes, greenish-red changing to dark brown, with gray scarf-skin, glossy, glabrous, with raised lenticels of medium size and number; leaf-buds short, obtuse, free. Leaves folded upward, broadly oblanceolate, peach-like, one and one-eighth inches wide, three and three-quarters inches long, thin; upper surface light green, smooth, pubescent only on the deeply grooved midrib; lower surface glabrous, pubescent on the midrib; apex taper-pointed, base cuneate, margin finely and doubly serrate, with small amber or reddish glands; petiole nine-sixteenths inch long, sparingly hairy on one side, tinged red, with from one to four small, reniform or globose glands mostly on the stalk. Blooming season early and short; flowers appearing with the leaves, white; borne in dense clusters on the lateral buds and spurs, in threes; pedicels one-quarter inch long, thick, glabrous; calyx-tube green, obconic, glabrous; calyx-lobes broad, obtuse, glandular-serrate, glabrous, erect; petals broadly oval, entire, short-clawed; anthers yellowish; filaments one-quarter inch long; pistil glabrous, longer than the stamens. Fruit early, season long; variable in size, large when the tree is not overloaded, one and three-quarters inches in diameter, roundish-conic, halves equal; cavity deep, abrupt, regular; suture shallow; apex roundish; color dark red over a yellow ground, mottled, with thick bloom; dots numerous, large, russet, conspicuous; stem five-eighths inch long, glabrous, parting readily from the fruit; skin thin, tough, sour, separating from the pulp; flesh deep yellow, juicy, tender, firm, sweet, aromatic; good; stone clinging, three-quarters inch by five-eighths inch in size, roundish-oval, turgid, blunt but sharp-tipped, roughish, with a slightly winged ventral suture; dorsal suture acute.
