serrate usually only above the middlf, about half grown when the flowers open early in 

 April, and then gray-green and coated above and on the lower side of the midrib and prin- 

 cipal veins w r ith short pale hairs, and at maturity thin and firm in texture, dark green, 

 lustrous and slightly pilose above, paler and pubescent below on the slender midrib and 

 2-5 pairs of primary veins, l'-2' long, and f'-l' wide; petioles slender, grooved above, 

 glandular, usually about \' in length; leaves at the end of vigorous shoots often broad- 

 ovate to elliptic, coarsely dentate or sometimes incisely lobed, frequently 2|' long and 

 2' wide. Flowers about f ' in diameter, on slender pedicels, in few-flowered compact 

 hairy corymbs; calyx-tube narrowly obconic, villose with long matted hairs, the lobes 

 narrow, acute, entire or irregularly glandular-serrate, usually glabrous on the outer surface, 

 villose on the inner surface; stamens 10; styles 3-5, surrounded at base by a few pale hairs. 

 Fruit ripening and falling toward the end of October, in few-fruited drooping slightly villose

clusters, short-oblong, rounded at the ends, dark red, more or less pruinose, marked by 

 numerous pale dots, and about \' long; calyx enlarged, with elongated closely appressed 

 lobes usually persistent on the ripe fruit; flesh thin and yellow; nutlets 3-5, prominently 

 ridged and grooved on the back, about \' long. 



A tree, usually 15-18 high, with a tall trunk 4'-5' in diameter, covered with ashy 

 gray bark, often nearly black near the base of old stems, and separating freely into thin 

 plate-like scales, numerous ascending or spreading branches forming a round-topped or 

 oval compact head, and stout chestnut-brown branchlets armed with stout, nearly straight 

 bright chestnut-brown spines l'-2' long. 



Distribution. Open glades and dry copses of the Pine-covered coast-plain of southern 

 Alabama. 



19. Crataegus edita Sarg. 



Leaves oblong-obovate or rarely elliptic, acute at the gradually narrowed apex, gradually 

 narrowed from near the middle to the cuneate entire base, and coarsely and often doubly 

 serrate above, when the flowers open from the 15th to the 20th of April lustrous and sca- 

 brate on the upper surface with short rigid pale hairs and puberulous on the lower surface, 

 and at maturity coriaceous, dark green, lustrous, and slightly roughened above, pale yellow- 

 green and scabrate below, l|'-2' long, and \'-\' wide; petioles stout, villose, becoming 

 pubescent or puberulous, \'-\' in length; leaves at the end of vigorous shoots often 

 slightly divided into lateral lobes, more coarsely serrate and sometimes 3' long, and 1^' 

 wide, with stout broadly winged petioles. Flowers \'-\' in diameter, on slender villose
