give a strong impression of tlie desert, whicli contrasts 

 forcibly witli civilized surroundings. The individual 

 flowers are not highly colored, but the spikes are 

 several feet long. Three plants sold as Dasylirions be- 

 long to Nolina, a closely related genus, which is chiefly 

 distinguished by fruit characters. In Dasylirion the 

 ovary has 3 ovules, and the fruit is dry and indehiscent, 

 or splits through the partitions and between the cells. 

 In Nolina the ovary has 2 ovules, and the fruit is dry, 

 often 3-winged, and bursts in an irregular fashion. The 

 latest monograph is in Latin by J. G. Baker in Journ. 

 Linn. Soc. Vol. 18 (1881).

 This is the only species with entire, not toothed, leaf-

 be almost globular ; the Ivs. are 4-6 ft. long, slightly 

 arching, and not splitting into fibers.

it has been grown for decorative purposes for more than 

 a century. At the missions founded by the Spaniards 

 at St. Augustine, and other places in Florida, and that 

 long line of missions extending from far iuto Mexico, 

 northward and westward through southern New Mexico, 

 Arizona and California, it is probable that the Date was 

 planted wherever the climatic conditions were favor- 

 able. Within the borders of the United States the 

 greater number of these early plantings were in Florida 

 or along the coast of southern California, regions where 

 the sum total of vummer hfat is not sufficientto perfectly 

 develop the nai-' fi-uit, I'lie Hatf. as a fruit producer, 

 being indiiriiKni- n. a .1. — it i-n .immnent, does not take 

 kindly to humi.l n ^'i.m-. , v. n wu. r- it is not sufficiently 

 cold to prohibit the gruwth of the tree. For this reason 

 the greater number of the early plantings in this country 

 matured little fruit, while that produced was of poor 

 quality, although in many instances the trees grew luxu- 

 riantly and to large size. In the more arid portions of 

 Lower California and Sonera, where there is suflicient 

 water for irrigation, the early plantings have been con- 

 tinued down to the present time, and Dates of fair 

 quality have been grown for many years. Moreover, 

 each year the area devoted to Dates is increasing. Not 

 only have sufficient Dates been grown in Sonora to sup- 

 ply the local markets and the markets of the larger 

 cities, Hermosillo, Guaymas and Altar, but during the 

 past year a surplus has been shipped from the state. 



The part of the United States suitable for growing 

 the Date tree, for the profitable production of fruit, is 

 confined to rather narrow limits; viz., the irrigable por- 

 tion of southern Arizona below an altitude of 2,500 feet 

 and the somewhat similar area of southern California 

 east of the coast ranges of mountains, where the sum- 

 mer temperature is not lowered by proximity to the sea. 

 As a tree, however, it will make excellent growth over 

 a much larger area, including the semi-arid regions of 

 central and southern California. Over the larger area 

 it will occasionally bloom and the earlier varieties ma- 

 ture fruit, but the summer heat will rarely be sufficient 

 to brinir it to a high degree of perfection. In recent 

 years [lat.-i hav.. matured in favorable localities in

situated on the California si.l. n. . iii.i.i river a 



few miles below Yuma. In Ihi.'i .Mr. Haul. -a received a 

 box of Dates from La Paz, Lower California, which were 

 grown at that place, and planted the seed the same year. 

 Prom these seeds 12 pistillate and several staminate 

 trees were raised, the trees beginning to bloom at the 

 age of 5 years. All the pistillate trees have fruited 

 abundantly each year since 7 years of age, and now vary 

 in height from 20 to 50 feet, each tree producing yearly 

 from 6 to 17 bunches of fruit, the bunches varying in 

 weight from 20 to 38 pounds. 



In recent years many seedling palms have come into 

 bearing in southern Arizona, particularly in Salt river 

 valley. On the Bartlett, Adams & Co's. ranch at Glen- 

 dale, several seedling Dates were in bearing in the 

 fall of 1898, at which time one tree, 8 years from seed, 

 bore an estimated crop of more than 400 pounds. On 

 a ranch owned by E. L. Arthur, in the vicinity of 

 Tempe, a dozen or more palms were in bearing the same 

 year, several of which bore one or more bunches of fruit 

 the fourth year after planting. In addition to those 

 cited above, many seedling palms bore during the fall
