Information

Sticky, glandular, perennial herb up to c. 60 cm. tall. Basal leaves up to 15 × 2·5 cm., spathulate-oblong, acute or obtuse, mucronate, narrowing into a petiole c. 2 cm. long; cauline leaves up to 8 × 2 cm. but usually smaller, lanceolate, oblong-lanceolate or narrowly elliptic, apex acute, cuneate and sessile or subsessile at the base, margin sometimes undulate. Flowers in terminal, lax, rather few-flowered paniculate cymes; bracts similar to the upper leaves, but progressively smaller upwards, lanceolate-acuminate; pedicels 0·6–2 cm. long, viscid-glandular, often in triads with the middle one shortest. Calyx 2·5–3·5 × c. 0·5 cm., cylindric, but dilated in fruit, 10-ribbed, viscid-glandular, teeth lanceolate-subulate, c. 5 mm. long. Petals white or pinkish, lamina c. 0·9 × 0·4 cm., spreading, bifid, with a linear claw somewhat longer than the calyx and lobes denticulate or entire; coronal scales dentate, c. 1·5 mm. long. Stamens on slender biseriate filaments, the longer c. 3·5 cm. long, the shorter c. 1·7 cm. long. Ovary narrowly oblong-ovoid, 1-locular, on a puberulous stalk up to 7·5 mm. long; styles 3, c. 1·5 cm. long, slender, papillate along one side. Capsule 1·2–1·8 × 0·8 cm., horny, oblong-ovoid, opening by recurved valves at the apex, on a stout stalk 1/3–1/2 the length of the capsule. Seeds many, almost black, c. 1·2 × 1 mm., reniform with flattened sides, minutely and concentrically tuberculate.
