Description
editAndrocalva lachna is an erect shrub that typically grows to 20–90 cm (7.9–35.4 in) high and 40–150 cm (16–59 in) wide, and has hairy young stems. Its leaves are egg-shaped, 10–30 mm (0.39–1.18 in) long and 12–19 mm (0.47–0.75 in) wide on a petiole 2–4 mm (0.079–0.157 in) long with stipules 3–7 mm (0.12–0.28 in) long at the base. The edges of the leaves are rolled under and have irregular serrations, both surfaces densely covered with white, star-shaped and glandular hairs. The flowers are arranged in heads of 4 to 12 on a peduncle 7–25 mm (0.28–0.98 in) long, each flower on a pedicel 2–9 mm (0.079–0.354 in) long, with triangular bracts 2–5 mm (0.079–0.197 in) long at the base. The flowers are 7–9 mm (0.28–0.35 in) wide with 5 white, petal-like sepals with a pink base, and 5 petals, the ligule shorter than the sepal lobes. There are 3 staminodes between each pair of stamens. Flowering occurs from August to November.[2]
