Characteristics

Herb 0.4–0.8 m high. Branchlets with fine bristles (0.2–1 mm long, scattered to very dense, the bristles ascending), hairs whitish. Stipules deciduous or persistent, linear, 3–9 mm long, 0.3–0.6 mm wide, with fine bristles. Mature leaves: petiole 20–65 mm long, indumentum similar to branchlet; lamina ovate to broadly ovate, unlobed to deeply 3-lobed (the lobes longer than wide), 55–95 mm long, 40–85 mm wide, cordate base, serrate to dentate margin, acute to acuminate apex, discolorous, the indumentum denser on lower surfaces, especially on raised midvein and veins, the abaxial surface with indumentum of scattered stellate hairs (rays 0.6–1.3 mm in diam., 3 or 4 rays per hair) and fine bristles, the adaxial surface with sparse simple hairs (to 1.2 mm long), hairs whitish. Distal leaves reduced in size and shape, ovate, broadly ovate or narrowly elliptic. Flowers solitary in leaf axils, pedunculate, 10–25 mm long, with sparse coarse bristles and moderately dense fine ascending bristles; pedicel 2–6 mm long, indumentum like peduncle, the pedicel marginally wider than peduncle distally; epicalyx notably absent in this species; calyx at anthesis not splitting (5-lobed but not splitting per se), lobes triangular, 3–6 mm long, calyx in fruit 9–11.5 mm long, indumentum of sparse stellate hairs, sparse coarse bristles, scattered fine bristles, nectary absent; petals 11–16 mm long, white, petal spot absent, glabrous adaxially, with very sparse stellate hairs abaxially, near apex, basally with a dense fringe of simple hairs on margins between petals; staminal column straight, 3.6–4.6 mm long, stamens distributed along the distal 3–3.5 mm of the column, stamens scattered, inserted singly, filaments 0.5–1 mm long, anthers white, pollen yellow; style 5-branched, branches 0.4–0.9 mm long, stigmas entire, 0.2–0.4 mm wide, capitate, the hairs 0.1–0.2 mm long. Capsule broadly ovoid, 6.5–8 mm long, sparsely hairy with spreading-ascending simple, soft hairs to 1.2 mm long on margins, shorter erect hairs on remainder, hairs in top half to two thirds of capsule, remainder glabrous, beak present, 1–1.8 mm long. Seeds subreniform to angular-reniform, 1.6–1.8 mm long, hairy with striate and minutely pectinate rusty hairs to 0.1 mm long.
More
Herbs annual, erect, 50-70 cm tall. Branchlets puberulent (hairs simple) and rarely sparsely stellate hairy. Stipules lanceolate, ca. 3(-8) mm, villous; petiole as long as or slightly longer than leaf blade, stellate, puberulent and villous; leaf blade membranous, dimorphic; blades on proximal part of stem ovate-orbicular, 1.5-3 cm, those in middle 3-parted, ca. 5 cm, on distal part of stem nearly divided or 3-foliate, margin roundly dentate, stellate pilose and puberulent abaxially, pilose adaxially. Flowers solitary or arranged in sparse racemes, axillary. Pedicel 2-2.5 cm, pilose, articulate near end. Epicalyx absent. Calyx cup-shaped, ca. 4 mm, membranous, lobes 5, lanceolate, abaxially pilose and strigose, persistent. Corolla yellow; petals 0.6-0.7 cm. Staminal column ca. 0.4 cm. Styles 5, extending. Capsule broadly ovoid, ca. 7 mm, apex beaked; mericarps 5, endocarp thin, villous along ventral suture. Seeds with scalelike hairs. Fl. Oct-Dec.
Leaf-lamina 2–12 × 1·5–10 cm., suborbicular to ovate in outline, varying on the same individual from not lobed to deeply 3–5-palmatilobed or incised, usually pubescent on both surfaces with additional longer simple hairs on the veins and 2–4-pronged hairs mainly on the lower surface, lobes sometimes secondarily pinnately lobed or incised, apex acute to subcaudate, margin bluntly toothed or crenate or irregularly lobed, base slightly to distinctly cordate 3–5-nerved; petiole up to 8 cm. long, pubescent or pilose or tomentellous; stipules 4–8 × 0·5–1 mm., filiform to narrowly linear.
A herb. It grows 50-70 cm tall. It is hairy. The lower leaves are oval and the leaves higher up are divided or have 3 leaflets. The lower leaves are 2 cm long by 3 cm wide. The flowers usually occur singly. The fruit is a broad capsule 7 mm across.
Flowers 1–2 cm. in diam., white to yellowish, in few-flowered terminal racemes; peduncle 10–20 mm. long, pubescent or pilose or tomentellous, articulated near the apex.
Seeds 1·5 × 1·3 mm., irregularly prismatic, minutely verruculose otherwise glabrous.
Calyx pubescent; lobes 5–7 × 1·5–2·5 mm., narrowly lanceolate, joined near the base.
Annual herb from 0·5–1·3 m. tall; young stems pubescent, pilose or tomentellous.
