Only a few species are found in temperature regions. This family produces little that is of real economic importance. Only 2 genera, Asimina and Anona. are represented by tree species in the United States. The genus Asimina does not have representatives outside of North America, where about 8 species are known to occur. The sole representative of this family native to this State is the species de- scribed on this page. FORM—A small tree usually 10-40 ft. in height with a diameter up to 12 inches. Trunk short and slender. Crown rather broad, high, and formed by straight rather spreading lateral branches. BARK—^Thln, close, sometimes slightly fissured, dark brown, often covered with scattered white blotches. TWIGS—Round, olive-brown, enlarged at the nodes, rather slender, at first often somewhat hairy towards apex; later smooth, covered with a few fine lenticels which become evident dur- ing second year; pith small and white. BUDS—Alternate, 2-ranked or sometimes 3-ranked, brown, naked, hairy. Terminal, lateral leaf and flower bnda differ in size and form. Terminal bud is much longer than the others and evidently flattened. Lateral leaf-buds about i of an Inch long, closely appressed to twig and located In notch on upper surface of leaf-scars. Flower-buds occur along the twig, spherical In outline, about 1/6 of an inch in diameter, very hairy and dark brown; do not stand quite parallel to twig. LEAVES—Alternate, simple, obovate-lanceolate, 4-12 Inches long, thin, pointed at apex, tapering at base, entire on margin, when mature dark green above and paler below. In au- tumn they turn rusty yellow. LEAF-SOARS—^Alternate, located on enlarged projections of the twig. Inclined at about an angle of 35 degrees to the twig, broadly U-8liai)ed, almost surround bud, somewhat lighter than the twig, contain usually 5 bundle-scars which are often compounded. A ridge extends across the leaf-scar from the bud to the base of the scar. FLOWERS—Appear about April or May with the leaves but are usiially located below them along the twigs. They occur solitar&gt;- and axillary: are perfect, at first green, later reddish- purple, 1-11 inches wide, and borne on stout hairy stalks. FRUIT—Suggests a stubby banana, is cylindrical, rounded, or occasionally blunt-pointed at the ends, 3-5 inches long, at first green, later dark-brown, pulp edible, contains many dark- brown, shiny, flattened seeds which are scattered throughout the flesh. WOOD—Ring-porous with a diffuse-pOTOus tendency; rays very numerous and distinct; heart- wood brownish; sapwood yellowish; weak, soft, weighs about 25 lbs. per cubic foot. Not used comniiercially. DISTINGUISHING CHARACTERISTICS—The Common Pawpaw can be recognized best In au- tumn by its unique fruit whic^ is very suggestive of a stubby banana. In spring the greenish- brown to reddish-purple flowers which occur solitary along the twigs and measure 1-1J inches across are also characteristic. The large, tropical-like, alternate leaves will also aid In recog- nizing It. In winter the long, slender, somewhat flattened, naked, brownish, terminal buds and the spherical flower-buds along the side of the twigs and Uie U-shaped leaf-scars which almost surround the buds and usually contain 5 bundle-scars, will enable one to distinguish it. The fact that it occurs only in about the southern third of the State may also help in dis- tinguishing it. RANGE—Western New York and west central New Jersey south to Florida and west to Michigan, Kansas, and Texas. DISTRIBUTION IN PENNSYLVANIA—Locally found in small groups in practically every county in the State south of a line drawn from Pittsburgh through Harrisburg and Reading to Doylestown in Sticks county. Reported as far north as Woodcock Valley, Crawford county, in the western part of the State. Also found near McElhattan in Clinton county. Not common anywhere but well known on account of its peculiar fruit. Usually found below altitude of 1,000 feet but in the South Mountains in Adams and Franklin counties found at 1,200 feet. HABITAT—Prefers rich moist situations. Usually found In river valleys near streams but occasionally ascends low fertile slopes. It may form dense thickets but in this State usually occurs solitary or in rather open groups. Occurs with other species in the understudy of the forest, and is very tolerant of shade. IMPORTANCE OF THE SPECIES—The Pawiiaw Is of no commercial Importance as a forest tree anywhere In Its range. The fruit which It produces is of more value than Its wood. It never reaches a large size, and In addition is local and limited in Its distribution. It is, how- ever, a very attractive tree on account of its somewhat drooping tropical leaves, handsomie flowers, and peculiar fruit.</i><br><b>Text Appearing After Image: </b><br><i>PLATE LXXX.
