Prunus angustifolia.âThe Chickasaw plum is a small tree, 6 to 10 feet high, sometimes shrubby. The fruit is small, almost globular, flesh yellow, and of good quality. It ranges from Delaware to Louisiana and westward to Arkansas and Texas. Its varieties do well in the Southern States. The two subspecies, walsoni and varians, have varieties of some horti- cultural value, such as Purple Panhandle, African, Clark, Emerson, etc. âleai bud kaj /growth xar CHERRIES Description.âThe cher- ries resemble plums in many respects. The bark of the cherry separates in rings. The flower huds are usually found on short spurs (Fig. 166). In some sour cherries, however, axillary flower buds occur on long, strong shoots. These buds produce fruit the following spring. Since the lateral buds in such shoots are flower-bearing, no lateral branches are pro- duced, and the result is a long, naked branch. On the spurs, the flower buds are axillary and a branch bud terminates the short shoot. The flower buds bear only flowers and no leaves (except very rudimentary ones which persist but for a short time).
