The Date Palm (Phoenix dactylifera) is an ancient fruit of the desert. Sections 208, 209, and 210 of Part I give something of its history, habits of growth, propagation, after-care, and possible improvement by crossing. In its native climes in Arabia, Northern Africa, and other dry desert regions of the old world, it has run into many-named varieties which are kept pure by propagation from suckers from the crown (209). Mr. W. G. Palgrave, who has given much attention to date varieties in the Far East, says: " The fruit varies as much in size, color, and quality under cultivation as does the apple in temperate regions." The Date Palm has long been grown in Florida, California, and other semi-tropical parts of the Union as an ornamental tree. As in such localities it failed to perfect fruit, no attempt has been made until recently to secure the best commercial varieties of the Far East. The remarkable success of the old Mission trees in Southern Arizona and Sonora, Mexico, in the way of bearing very heavy crops of good fruit, led the Department of Agriculture to import named varieties from the Far East. The first fruiting of these at Phoenix, Arizona, determined the fact that they were not true to name, and fully half of them were staminate varieties. But later importations have been made with more care, and it is hoped that in the near future the best seedling varieties of the old Missions and of those imported will be commercially planted in Southern Arizona and in the sunken desert of California. The seeds of the commercial dates from Algeria, Syria, and Egypt germinate readily. Often they sprout and grow on the unpaved streets of prairie villages and small cities where the seeds are dropped. The pistillate varieties from these seeds usually bear very good fruit, but it is variable, and the proportion of staminate trees is much too great, as one staminate to twenty pistillates is the usual proportion in Arizona. At the present time, as Prof. J. W. Tourney says: "The Date industry of the United States is in its infancy. Approved varieties have not as yet been introduced, and the quantity of fruit produced has not reached sufficient magnitude to give it a commercial rating." Hence at this time no description of varieties is advisable. The only important fact established is that in the strictly desert regions of Southern Arizona and Southeast California the old seedling dates are as thrifty and as heavy bearers of fruit as in any part of Algeria where date-growing is commercial.
