This tree shows a marked tendency to run into varieties, and cultivation would probably develop the tendency. The differences between the species and the varieties are plain enough to the systematic botanist, but are such that the lumberman or other ordinary observer would scarcely notice them. The variety which has been named _Celtis mississippiensis reticulata_, but without any English name except sugarberry, is a tree forty or fifty feet high, covered with blue-gray bark, very rough. It ranges from Dallas, Texas, to the Rio Grande and westward into New Mexico, Arizona, and Utah, and into southern California and Lower California. In eastern Texas it is found on dry limestone hills, but westward only in mountain canyons in the vicinity of water. In the southern part of Texas this tree is usually known as palo blanco, but those who apply that name have no idea that it is a variety of sugarberry but suppose it is a tree peculiar to their region. In Cameron and Hidalgo counties, Texas, either because an extra good quality grows there, or because some opinion exists in its favor, it is liked for wagon material, and occasionally is turned for table legs and other parts of furniture. It is quite common in that part of Texas as an ornamental tree in yards and along streets of small towns. The whiteness of the bark is the most striking feature. [Illustration] WHITE ASH [Illustration: WHITE ASH] WHITE ASH (_Fraxinus Americana_) This tree is generally called white or gray ash, or simply ash. American ash is a translation of its botanical name and is not often used in business transactions in this country. In some parts of the South the term cane ash is occasionally employed, but there seems to be no agreement among those who use the name as to what it means. This is the common ash in the lumber trade. There are more than a dozen species in the United States, but white ash goes to market in larger amounts than all others together. This is known in a general way, but exact figures cannot be given, because statistics of the cut of different species of ash are not kept separate.
