glandular-serrate except toward the glandular base, thin but firm in 
texture, dark dull blue-green on the upper surface, pale yellow-green 
on the lower surface, 4-6 cm. long, 2.5—4 cm. wide, with thin orange- 
colored midribs and usually four pairs of slender primary veins; 
petioles slender, slightly wing-margined toward the apex, glandular, 
with small dark glands, 2-3 cm. long; stipules linear, acuminate,

often 1 cm. in length. Flowers about 1.5 cm. in diameter on slender 
elongated pedicels in 4—7-flowered compound corymbs; bracts and 
bractlets linear to oblong, acuminate, coarsely glandular-serrate, 
reddish, large and conspicuous, caducous;  calyx-tube broadly 
obconic, the lobes gradually narrowed from broad bases, coarsely

stems covered with pale gray bark, spreading branches, and thin 
nearly straight branchlets marked by occasional small pale lenticels, 
bright chestnut-brown and lustrous during their first season, becoming
