(Figs. 1, 2, 4, 5).
Herbaceous, ascending to erect, annual. Rootstock stout, compressed, completely crowded by ascending shoots, basal leaf petioles and stipules. Tape root up to 5.5 cm long, vertical-oblique, woody, smooth bearing thin roots. Stem clothed with pilose ca. 3 mm long, spreading eglandular hairs, 0.3–0.4 mm long, retrose not appressed, curved, dense, eglandular hairs and upper half with 0.15–0.45 mm long, spreading, glandular hairs. Stipules 1–2.5 mm long, lanceolate-subulate, sometimes bifid at apex, abaxially with few scattered eglandular hairs, adaxially glabrous, margins with pilose 1.1–2.5 mm long eglandular hairs and 0.2–0.7 mm long, eglandular hairs. Leaf opposite; petiole 1–8 cm long, covered with retrorse, curved, slightly dense 0.2–0.35 mm long, eglandular hairs, long patent, 1.4–2.5 mm long, pilose, eglandular hairs and 0.1–0.4 mm long, spreading glandular hairs; lamina 0.9–2.1 × 1–2.5 mm, reinform-polygonal, palmatipartite (ratio of main sinus length/middle segment length 0.57– 0.66), 5 segments, obtriangular, middle segment width at base 1.2–4.0 mm, 7–12 lobes, either short or as long as broad, acute-obtuse (ratio of 2 nd sinus length/ middle segment length 0.14–0.20), eglandular hairs along the veins, sometimes glandular hairs on upper surface, papillose type eglandular hairs absent. Inflorescence monochasial cyme, cymule solitary bear 1 or 2 pedicilate flowers, sometimes umbelled without peduncles; peduncles (0-) 1–8 cm long, with 0.2–0.5 mm long retrorse, curved eglandular hairs and 0.1–0.3 mm long, spreading glandular hairs; bracteoles 1.5–3.4 × 0.3–0.6 mm, lanceolate, ciliate margins, adaxially glabrous, abaxially with eglandular hairs; pedicel 0.2–3 cm long with 0.1–0.3 mm long, retrose, not appressed, curved eglandular hairs and spreading 0.2–0.45 mm long glandular hairs. Flowers actinomorphic with black spot at base. Sepal 4.1–4.8 × 1.7–3.6 mm, lanceolate, not accrescent, margins curving inwards, lateral veins slightly crenate, mucro 0.5–0.65 mm long with few hairs, adaxial surface glabrous, abaxially with 1.1–3 mm long eglandular hairs, 0.1–0.3 mm, sparse, eglandular hairs and 0.25–0.5 mm long, glandular hairs along the veins, margins without cilia. Petals 7.8–9 × 5.6–6.2 mm, obovate, with dark purple spot at base, apex slightly dented 0.15–0.25 mm deep notch, both surfaces glabrous, margins at base ciliate up to 1–2 mm length. Stamens 10 in 2 whorls; filaments 2.6–3.1 × 0.3–0.35 mm, roughly lanceolate, dilated at base up to middle half tapering smoothly into narrow apex, glabrous; anthers 0.8–1.0 mm long.
