numerous short acute lateral lobes, glabrous with the exception of a few pale caducous 

 hairs on the upper surface and bronze-yellow when they unfold, nearly half grown when 

 the flowers open about the 20th of April and then thin, dark yellow-green above and pale 

 below, and at maturity thin but firm in texture, dark blue-green on the upper surface, pale 

 on the lower surface, 1%'-%' long, and I'-l |' wide, with a slender yellow midrib and 3 or 4 

 pairs of thin primary veins; petioles slender, often short-winged at the apex, usually about 

 f in length; leaves at the end of vigorous shoots often 3' long and 2' wide, sometimes deltoid 

 and usually much more deeply lobed. Flowers f in diameter, on slender pedicels, in 

 usually 5-7-flowered compact glabrous corymbs; calyx-tube broadly obconic, glabrous, the 

 lobes gradually narrowed from a broad base, acuminate, entire or obscurely and irregularly 

 serrate, glabrous; stamens 20; anthers small; light rose color; styles 5; surrounded at the 

 base by a narrow ring of pale tomentum. Fruit ripening and falling early in October, on 

 slender pedicels, in drooping few-fruited clusters, short-oblong, full and rounded at the

ends, often obscurely 5-angled, dull russet-green, f'-' long; calyx-lobes only slightly 

 enlarged, mostly deciduous before the fruit ripens, leaving a well-defined ring at the summit 

 of the short calyx-tube; flesh thin, light green; nutlets 5, thin, rounded and irregularly 

 grooved on the back, about \' long. 



A tree, sometimes 25-30 high, with a tall trunk 10'-12' in diameter, stout wide-spread- 

 ing branches forming a broad symmetrical round-topped head, and slender lustrous chest- 

 nut-brown branchlets armed with straight or slightly curved thin spines rarely more than 

 iy long. 



Distribution. Low rich river-bottoms and meadows in the neighborhood of Rome, 

 Floyd County, Georgia. 



56. Crataegus callicarpa Sarg. 



Leaves ovate, acute, cordate at base, coarsely often doubly serrate with long straight 

 glandular teeth, and slightly divided into 3 or 4 pairs of short broad acuminate lateral 

 lobes, not more than a quarter grown when the flowers open late in April and then very 

 thin, yellow-green and slightly villose above and on the midrib below, and at maturity 

 thin, glabrous, dark yellow-green and lustrous on the upper surface, pale yellow-green on 

 the lower surface, 4 '-4^' long, and 2'-2^' wide, with a stout midrib, a,nd 3 or 4 pairs of prom- 

 inent primary veins connected by conspicuous cross veinlets; petioles stout, slightly wing- 

 margined at apex, sparingly glandular, I'-lJ' in length; leaves at the end of vigorous shoots 

 thicker, with shorter glandular petioles rose-colored toward the base. Flowers 1' in diam- 

 eter, on short stout pedicels, in small compact 5-10-flowered corymbs, with lanceolate to
