“Naturally, the settlers who went every year to the sand hills for plums brought back trees to plant in the gardens they were opening. Almost every farm within the range mentioned above had a few or many of the dwarf trees growing. Some of these were fruitful and worth their room, but most of them have now died out, or are neglected and forgotten. This is because people have paid no attention to their selection, propagation and cultivation. Further than this, however, the sand plum has often failed signally to come up to its record when transferred to cultivation. It seems not to adapt itself readily to a wide diversity of soils and conditions.” The sub-species is easily mistaken for the species; in herbarium specimens it is almost impossible to distinguish between them, but in general the Sand plum differs from Angustifolia in its dwarfer habit, shorter-jointed, zigzag, ashy-gray branches, smaller but thicker leaves, larger, thicker skinned and better flavored fruit which ripens later, and in a smaller and somewhat differently marked stone. In distinguishing the two groups some allowance must be made for the adaptability of plums to different environments. =PRUNUS ANGUSTIFOLIA VARIANS= Wight and Hedrick Plant a small tree, attaining a height of twenty-five feet; trunk small but well-defined; branches spreading, bushy, sometimes armed with spinescent branchlets; young wood slender, more or less zigzag, usually glabrous, glossy, reddish but approaching a chestnut-brown; lenticels few, scattered, yellowish, raised. Leaves oblong, oval-lanceolate or rarely slightly obovate-lanceolate, one and one-fifth to two and one-fifth inches long, three-quarters to one inch broad, gradually narrowed at the base, acute at the apex; margins very minutely glandular-serrate; upper surface glabrous and somewhat lustrous; lower surface paler, glabrous or sparingly hairy along the midrib and in the axils of the lateral veins; petioles slender, usually reddish, about one-half inch long, pubescent along the upper side, eglandular or sometimes with one or two glands at the apex; stipules small, linear and glandular-dentate. Flowers appearing from early in March and before the leaves in the South, to the middle of April and with the leaves in the North, in dried specimens about one-half inch broad; pedicels three-eighths to one-half inch long, glabrous; calyx campanulate, the tube glabrous; calyx-lobes usually shorter than the tube, oblong and obtuse, glabrous on the outer surface, glabrous or sometimes sparingly pubescent on the inner, the margin ciliate, eglandular; petals obovate, gradually narrowed toward the base, erose or entire toward the apex.
