Begonia grandis subsp. sinensis (A. Candolle) Irmscher
中华秋海棠 zhong hua qiu hai tang
Begonia sinensis A. Candolle, Ann. Sci. Nat., Bot., sér. 4, 11: 125. 1859; B. bulbosa H. Léveillé; B. martini H. Léveillé.
Stem 20-40 cm tall, weak, usually not branched. Leaf blade abaxially pale, occasionally reddish, elliptic-ovate or triangular-ovate, 5-12(-20) × 3.5-9(-13) cm, both surfaces glabrous or subglabrous. Filaments connate for less than 2 mm. Styles connate or slightly connate at base, branched; stigma spirally tortuous, rarely U-shaped.
● Forests, on limestone rocks in shaded moist environments, on slopes, or in valleys; 300-3400 m. Fujian, S Gansu, Guangxi, Guizhou, Hebei, Henan, Jiangxi, Shaanxi, Shandong, Shanxi, E Sichuan, Yunnan, Zhejiang.
Begonia grandis var. puberula Irmscher (Mitt. Inst. Allg. Bot. Hamburg 10: 496. 1939) differs in having a leaf blade adaxially densely hispidulous (hairs ca. 0.3 mm) and sparsely hirsute (hairs 0.8-0.9 mm), while var. villosa T. C. Ku (Fl. Reipubl. Popularis Sin. 52(1): 166. 1999) differs in having a leaf blade adaxially slightly floccose.
