acute lateral lobes, and often 4'-5' long and wide, with foliaceous, lunate, coarsely 

 glandular-serrate stipules, 1^' wide, and persistent throughout the season. Flowers 



I"' in diameter, on slender densely villose pedicels, in broad lax many-flowered long- 

 branched hairy corymbs, the lower peduncles from the axils of upper leaves and 

 often several-flowered, their bracts lanceolate, glandular, large and conspicuous, per- 

 sistent until after the flowers open ; calyx-tube narrowly obconic, covered with a thick 

 coat of long matted hairs, the lobes slender, elongated, acuminate, serrate, with occa- 

 sional large gland-tipped teeth, glabrous on the outer, slightly villose on the inner 

 surface; stamens usually 5; anthers pink; styles mostly 5. Fruit ripening the middle 

 of September and soon falling, on long slender slightly hairy pedicels, in many- 

 fruited drooping clusters, short-oblong, full and rounded at the ends, yellowish red, 

 glaucous, marked by occasional pale dots, about |' long and -|' wide; calyx sessile, 

 with usually erect enlarged coarsely serrate lobes villose on the upper side and often 

 deciduous from the ripe fruit; flesh thick, yellow, rather juicy; nutlets usually 5, 

 narrowed and acute at the ends, ridged with a high broad ridge, or rounded and 

 slightly grooved on the back, about |' long. 



A tree, 2o-30 high, with a short trunk occasionally 4'-o' in diameter, covered 

 with smooth light gray bark, numerous erect branches forming an oblong open very 

 irregular head, and stout slightly zigzag branchlets coated when they first appear 

 with long matted pale hairs, light red-brown and lustrous, marked by small pale len- 

 ticels and pubescent at the end of their first season, becoming dull red or orange- 

 brown the following year, and armed with stout straight or curved bright red-brown
