TREES OF NORTH AMERICA 



May when the flowers open, and then thin, dark yellow-green above and pale below, and 

 at maturity subcoriaceous; pale on the lower surface, 2'-2-|' long, and I'-l^' wide, with a 

 stout midrib and primary veins deeply impressed on the upper side of the leaf, and con- 

 spicuous reticulate veinlets; petioles stout, villose, more or less winged above, \'-% in 

 length; leaves at the end of vigorous shoots broad-ovate, cuneate and decurrent on their 

 stouter petiole, 3'-4' long, and 2'-3' wide, with lunate coarsely glandular-dentate stipules 

 frequently \' long. Flowers f ' in diameter, in broad loose usually 10-12-flowered corymbs, 

 with broad acute conspicuous glandular-serrate bracts and bractlets; calyx-tube broadly 

 obconic, densely villose at the base and glabrous or pubescent above, the lobes elongated, 

 gradually narrowed from a broad base, acute, bright green, more or less hairy, coarsely 

 glandular-serrate, with large stipitate dark red glands; stamens 10-20, usually 20; anthers 

 large, light yellow; styles 3-5. Fruit ripening and falling early in October, subglobose, 

 often rather longer than broad, bright red or orange-red, marked by numerous large dark 

 dots; calyx enlarged, w y ith spreading glandular lobes often deciduous before the fruit ripens; 

 flesh yellow, thick, dry and mealy; nutlets 3-5, narrowed at the ends, \' long. 



Fig. 470 



A tree, sometimes 25 high, with a trunk 10'-12' in diameter, covered with light gray or 

 gray-brown bark, and often armed with straight or much-branched spines, wide-spreading 

 light gray or reddish branches forming a rather open symmetrical head, and slender branch- 

 lets coated when they first appear with long spreading white hairs, pubescent or glabrous 

 and light red-brown or orange-brown during their first season, becoming dark or light gray 

 the following year, and furnished with numerous usually stout straight dark reddish brown 

 shining spines l'-2' long. 



Distribution. Dry limestone hills and ridges; West Nashville, Davidson County, 

 Tennessee; common. 



119. Crataegus Ashei Beadl. 



Leaves broad-ovate or occasionally obovate, acute and generally short-pointed at apex, 

 gradually or abruptly narrowed and cuneate and usually entire at base, coarsely and occa- 

 sionally doubly serrate above with straight or incurved teeth tipped with small dark glands, 

 when they unfold roughened on the upper surface w r ith short pale hairs and pubescent 

 below, nearly fully grown and membranaceous when the flowers open early in May, and at 

 maturity thin but firm in texture, pale and puberulous on the lower surface on the slender 

 midrib and primary veins, about 2' long and If wide; petioles stout, broadly winged above, 

 glandular, pubescent early in the season but ultimately nearly glabrous, about f in length;
