Fruit ripening and beginning to fall early in September, on stout villose or glabrous pedi- 

 cels, in large drooping few-fruited clusters, obovoid or short-oblong, bright red, often 

 slightly pruinose, marked by numerous minute pale dots, f'-f long, '--' in diameter; 

 calyx enlarged, prominent, with spreading or erect and incurved coarsely serrate persistent 

 lobes, their upper surface bright red below the middle and covered above with soft white 

 hairs; flesh thick, orange-yellow, soft, juicy and acidulous; nutlets 4 or 5, thin, narrowed

A tree, often 20 high, with a tall trunk 8'-10' in diameter, covered with light grayish 

 brown slightly fissured bark, large spreading and drooping branches forming an open head 

 often 20 across, and slender branchlets olive-green and slightly hairy when they first appear, 

 dull red-brown and marked by many large pale lenticels during their first season, becoming 

 light gray and rather lustrous, and armed with stout straight dark purple shining ulti-

hairs and densely tomentose below, particularly on the midrib and veins, about one fourth

 and villose below, and at maturity thin, light yellow-green and scabrate on the upper sur- 

 face, pale yellow-green on the lower surface, 2|'-3' long, and 2'-2' wide, with a slender 

 midrib often slightly hairy near the base, and 4 or 5 pairs of thin primary veins extending 

 obliquely to the point of the lobes; petioles slender, densely villose early in the season, 

 slightly hairy in the autumn, and f'-l|' in length; leaves at the end of vigorous shoots 

 often truncate or slightly cordate at base, deeply lobed with broad triangular lobes, and 

 3|'-4' long and wide, with a stout rose-colored glandular petiole, and hairy lunate glandular-
