Inflorescence umbellate, with 3‒6 flowers. Pedicel ca 2.1 cm long, glabrous or puberulent. Hypanthium usually glabrous. Sepals lanceolate to ovate triangular, abaxially glabrous, adaxially puberulous, caducous, rarely persistent. Petals ca 1.2 × 0.7 cm, white to red, obovate. Stamens 15‒20, unequal. Styles 3, rarely 4, longer than stamens, basally puberulent. Pome ca 0.8‒0.9 cm in diameter, subglobose, yellow to red. Carpopodium ca 2.9 cm long, glabrous or puberulent at base.

Note
The syntypes of Pyrus hupehensis Pamp. were collected in Sian-men-kou (Silvestri 939) and Ma-pauscian (Silvestri 940, 940a), Hubei (Hupeh), China. However, there are photographs from as early as 1932 in the Biondi herbarium at the Botanical Museum in Florence according to the record of Rehder, and now a scan of Silvestri 939 is available online in herbarium of Arnold Arboretum. Langenfeld designated a lectotype in 1991: 160 (CHINA • Fujian, Chongan, Sanghan-Tinmu-Guan; 11 Aug. 1952; Zhou Zhenying 239; lectotype: LE), but it is invalid because the type specimens have not been lost.
Distribution
China (Anhui, Chongqing, Fujian, Gansu, Guangxi, Guizhou, Henan, Hubei, Hunan, Jilin, Jiangsu, Jiangxi, Shandong, Shanxi, Shaanxi, HongKong, Yunnan, Zhejiang) (Fig. 11).
Chromosome numbers
