Dumasia hirsuta Craib (1914: 116) . Type :— CHINA . “W Hupeh: Patung Hsien”, alt. 1000‒1300 m , July 1907 , E. H. Wilson 3483 ( lectotype K!; isolectotype BM !). “Hupeh : Patung”, A.

Hunan : Shimen County : Nanping : “Sangerou”, alt. 300 m , 19 th August 1981 , Lin-Han Liu 17950 ( holotype HNNU ; isotype CPU ). Description: —Perennial twining herbs 1‒ 3 m . Stems and petioles densely covered with brown base-branched hirsute hairs. Leaves trifoliolate; stipules lanceolate, 4‒7 mm , striated; petioles 2‒13 cm , densely hairy; leaflets ovate to broadly ovate, 1‒9 × 1‒7 cm , membranous, glabrous adaxially, glabrous or sparsely pubescent abaxially, secondary veins 4‒6 pairs, retuse or obtuse at apex, apiculate; terminal leaflets rounded or broadly cuneate at base; lateral ones oblique, truncate at base; stipels small, setaceous; petiolules 2‒3 mm , ± covered with brown hairs. Inflorescence an axillary pseudoraceme, 1‒10 cm , 2‒18-flowered, pubescent to almost glabrous; bracts and bracteoles minute, setaceous. Pedicels 1‒3 mm . Flowers ca. 18 mm . Calyx tubular, 5‒8 mm , glabrous or sparsely with appressed hairs, obliquely truncate at apex. Corolla yellow to light yellow; standard ca. 17 × 9 mm , with a basal claw ca. 7 mm ; wings and keels as long as the standard. Ovary 4‒8-ovuled. Pods linear, flat, 4‒7 cm , ca. 1 cm wide, glabrous, with raised veins, beaked at apex, attenuate at base. Seeds 4‒7, brownish black. Distribution and habitat: — Dumasia hirsuta is mainly distributed in the southern part of China : Chongqing , Fujian (currently known from online photos, http://ppbc.iplant.cn/tu/4455394), Guangxi , Guizhou , Hubei , Hunan , Jiangxi , Shaanxi , Sichuan , and Yunnan ). It grows in moist valleys, forests, hill slopes, roadsides, or thickets at elevations between 400‒2100 m above sea level. Phenology: —Flowering and fruiting from May to September. Notes: —Although Yang et al. (2004) indicated that D. hunanica resembles D. villosa and D. truncata , key morphological characteristics mentioned by the authors ( i.e. base branched bristles along stems and petioles, ovate leaflets, sparse hairs on abaxial surface, and glabrous pods) are consistent with the characteristics of D. hirsuta , so here we synonymize D. hunanica with D. hirsuta . Iconography citation: — Wei (1995: 250) : plate 61: 9. Conservation status: — Dumasia hirsuta is widespread in South China and considered as Least Concern (LC) according to IUCN Categories (2019).
