Information

Erect sparsely to much-branched annual herb 5–35 cm. tall; stems covered with patent or crisped, often glandular, hairs. Leaves ovate to ovate-lanceolate, 0.5–2.5(–4.8) cm. long, 0.2–0.6(–0.9) cm. wide, acute at apex, tapering or rounded at base, usually with only a few hairs but occasionally pubescent. Flowers sessile or subsessile (peduncles and pedicels up to 1 mm.). Calyx-tube 1.1–2 mm. long, sparsely covered in patent or shorter crisped hairs; lobes ovate, 1.3–2 mm. long, 0.6–1.2 mm. wide, acute, glabrous or sparsely pubescent outside. Petals yellow, fading to white, always shorter than sepals, round to ovate, l–l.3(–l.6) mm. long, 0.55–1 mm. wide, usually distinctly apiculate, narrowed to base, entire to finely or irregularly crenate towards apex, with midvein alone distinct. Filaments 0.3–1.1 mm. long, translucent with vein apparent, with a small membranous hairy scale-like appendage at the base; anthers 0.15–0.4 mm. long. Style-bases distinctly thickened, not separating for 0.15–0.3 mm. above the disc; styles 0.7–1.3 mm. long, glabrous. Capsule 1.4–2.2 mm. long, sparsely pubescent. Seeds straw-coloured, ovoid-cylindrical, 0.15–0.27 mm. long, with indistinct longitudinal ridges. Fig. 1/1–8.
