FloTvers ^'-f in diameter, on long slender pedicels, in broad lax many-flowered 

 sparingly villose corymbs; calyx narrowly obconic, glabrous, the lobes slender,

 somewhat enlarged, with spreading or closely appressed lobes; flesh thin and firm; 

 nutlets 3-5, rounded at the ends, slightly ridged on the back, about -^' long. 



A tree, 18-20 high, with a trunk sometimes 8' in diameter, spreading branches, 

 and branchlets sparingly villose, with long matted white hairs when they first appear, 

 soon glabrous, and unarmed or armed with occasional straight slender spines about 

 11' long. 



Distribution. Banks of streams in eastern Mississippi; common in the neighbor-

14. Crataegus signata, Beadl. 



Leaves obovate, rounded and often short-pointed or acute at the apex, gradually 

 narrowed from near the middle and cuneate at the entire base, sharply glandular- 

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



in April, and then gray-green and xjoated above and on the lower side of the midribs 

 and principal veins with short pale hairs, and at maturity thin but firm in texture, 

 dark green, lustrous and slightly pilose above, paler and pubescent below along the 

 slender midribs and 2-5 pairs of primary veins, l^'-2' long, |'-1' wide; their petioles 

 slender, grooved above, glandular, usually about ^' long; on leading shoots often 

 broadly oval, coarsely dentate or sometimes incisely lobed, frequently 2^' long and 

 2' wide, with lunate coarsely glandular-dentate stipules. Flo"wers about |' 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 the base by a few pale hairs. 

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

 slightly villose clusters, short-oblong, full and rounded at the ends, dark red, more 

 or less pruinose, marked by numerous pale dots, and about ^' long; calyx enlarged,
