Leaves ovate to oval, acute, acuminate or rarely rounded at apex, acutely 

 or broadly cuneate at base, and coarsely doubly serrate with straight teeth, 

 covered above with short white hairs and densely villose-pubcscent below

 and 3-6 cm. wide, with a prominent midrib and lliin conspicuous primary 

 veins; petioles slender, slightly wing-margined at apex, lioary tomentose 

 early in the season, becoming glabrous, 1-3 cm. in length; leaves at the end 

 of vigorous shoots broadly ovate, acuminate, rounded or cuneate at the 

 broad base, more coarsely serrate, usually laterally lobed with short broad 

 acuminate lobes, and often 9 cm. long and 7-8 cm. wide. Flowers 2 cm. 

 to nearly 2.5 cm. in diameter, on short pedicels densely covered like the 

 narrow obconic calyx-tube and the compact 5 10-flowcred corymb with 

 long matted white hairs; calyx-lobes slender, long-acuminate, minutely 

 glandular-serrate, slightly villose; stamens 5-10, usually 10; anthers rose 

 color; styles 3 5, surrounded at base by a broad ring of pale tomentum. 

 Fruit ripening in September, on slender drooping pubescent pedicels, sub- 

 globose, orange-red, about 1 cm. in diameter, the calyx prominent with a 

 short tube and spreading closely appressed lobes; flesh thin, soft and yellow; 

 nutlets 3-5, rounded at base, narrowed and rounded at apex, slightly 



grooved on the back, 5 cm. long. 



A tree 0-7 m. high, with a trunk sometimes 15 cm. in diameter, spreading 

 branches forming a broad flat or round4opped head, and stout zigzag 

 branchlets coated when they first appear with matted white hairs, reddish 

 brown, pubescent or puberulous during their first season and gray the fol- 

 lowing year, and armed with few or many slender straight purple lustrous
