branches forming a narrow open head, and slender slightly zigzag 

 glabrous branchlets dull orange-green and marked by many small 

 pale lenticels when they first appear, becoming light orange-brown

 the calyx-lobes. Leaves oblong-obovate, acuminate, gradually nar- 

 rowed to the long slender acuminate entire base, finely serrate above, 

 with minute incurved teeth, and only slightly lobed near the apex; 

 nearly fully grown when the flowers open during the first week

 pale below, and at maturity subcoriaceous, dark green and very 

 lustrous on the upper surface, pale on the lower surface, 5.5-7 cm 

 long and 2.5-3 ^^ wide, with stout yellow midribs, and thin very 

 prominent primary veins extending obliquely toward the apex of 

 the leaf ; petioles slender, narrowly wing-margined nearly to the 

 middle, 1.5-2.5 cm in length; leaves on vigorous shoots oblong to 

 obovate, narrowed to the ends, more coarsely serrate, often deeply 

 divided into i or 2 narrow acuminate lateral lobes, frequently 

 9-10 cm long and 4.5-6 cm wide, with stout broadly winged petioles. 

 Flowers 1.3-1.5 cm in diameter, on long slender pedicels, in wide lax 

 many-flowered corymbs, the lower peduncles from the axils of upper 

 leaves; calyx-tube narrowly obconic, glabrous, the lobes slender, acu- 

 minate, finely glandular serrate, glabrous on the outer, sparingly 

 villose on the inner surface, reflexed after anthesis ; stamens 20; 

 anthers pale pink ; styles 2-4. Fruit ripening the middle of October, 

 on long slender reddish pedicels, in drooping few-fruited clus- 

 ters, oblong-obovate, rounded at the apex, gradually narrowed 

 from below the middle, abruptly compressed at the ofte\i oblique base 

 and decurrent on the pedicels ; calyx little enlarged, with a very 

 narrow deep cavity, and spreading closely appressed persistent
