 midribs and pale and glabrous on the lower surface, at maturity 

 subcoriaceous, dark green and very smooth above, pale below, 

 conspicuously reticulate- venulose, 6-7 cm long and 5-6 cm wide, 

 with slender midribs and primary veins deeply impressed on the 

 upper side of the leaf; petioles stout, wing-margined at the apex, 

 deeply grooved, villose on the upper side while young, becoming 

 glabrous, 1.5-2 cm in length. Flowers r. 2-1.4 cm hi diameter, on 

 slender slightly villose pedicels, in wide many-flowered corymbs; 

 calyx tube narrowly obconic, glabrous, the lobes slender, acuminate, 

 glandular-serrate below the middle, glabrous on the outer, villose on 

 the inner surface, reflexed after anthesis; stamens 10; anthers dark 

 rose color; styles two or three. Fruit ripening early in September, 

 in many-fruited drooping clusters, subglobose to obovate, full and 

 rounded at the ends, crimson, lustrous, marked by numerous small 

 pale dots; calyx enlarged and prominent, with a deep narrow cavity 

 and foliaceous coarsely serrate reflexed and appressed lobes, dark 

 red and villose on the upper side and mostly persistent on the ripe 

 fruit; flesh thin, dry and yellow; nutlets usually two, rounded and 

 obtuse at the ends, irregularly ridged on the broad back, deeply 

 penetrated on the inner face by broad irregular cavities, 6-7 mm 

 long and about 5 mm wide. 



A tree or treelike shrub 6-7 m high, with a trunk sometimes 

 15-18 cm in diameter covered with dark gray scaly bark, large
