 shoots cordate or truncate at the broad base, more coarsely serrate, 

 more deeply lobed, often 5-6 cm. long and broad, with stout midribs, 

 prominent primary veins, and stout winged conspicuously glandular 

 petioles. Flowers 1.6-1.8 cm. in diameter, on long slender pedicels,

 surface, reflexed after arithesis; petals often tinged with pink; stamens 

 10; filaments pink; anthers purplish pink; styles 3 or 4, usually 4. 

 Fruit ripening in October, on short red drooping pedicels, in few- 

 fruited clusters, short-obovate, nearly truncate at the apex, gradually 

 narrowed, long and rounded at the base, scarlet, marked by large pale
