Its representativeB occur as trees or shrubs in eastern North America, Central America. South America and Europe but are most abundant in Asia. The White Mulberry (Moms alba L.) a native of Asia, has been planted extensively in this State, and In some localities has escaptd cultivation. FOEM—Usually attains a height of 35-50 ft. with a diameter of 12-18 inches but may reach a height of 70 ft. with a diameter of 3 feet. Largest in Ohio and Mississippi valleys. Trunk usually short, subdividing near the ground. Crown usually broad, round-topped, and dense. BARK—Begins to roughen about third year by splitting longitudinally or diagonally. On older trunks rather thin, dark grayish-brown, peels off in long narrow flakes which somewhat resemble the flakes of CaUlpa bark. See Fig. 76. TWI&S—Stout, smooth, glossy or occasionally dull, slightly jsigzag, greenish-brown tinged with red, enlarged at nodes to bear buds and leaves, covered with few scattered inconspicuous lenticels, roughened at base of season's growth by ring-like bud-scales scars. A milky juice Is excreted from twigs if they are cut or punctured. BUDS—Alternate; terminal bud absent; ovate, round in cross-sect ion, sharp-pointed, about 2/5 of an inch long, sllghUy divergent and laterally inclined, covered by 8-9 exposed bud-scales which are 2-ranked, greenish-brown to greenish-red with darked margin. Buds are located on twig enlargements. A bud is often found at end of twig; it is not a terminal bud but an axillary one sometimes called a pseudo-terminal bud, which means false terminal bud. LEAVES—Alternate, simple, ovate, 3-5 inches long, often cordate at base, serrate on margin, acute at apex, usually with 8 primary veins, except in lobed fo
