Description
editStreptoglossa decurrens is a shrub growing to 70 cm (28 in) high. The leaves and branches are strongly fragrant, sticky and covered with soft, weak, thin hairs to long, soft, straight hairs and thickly glandular. The stems are upright leafy, older branches maybe leafless. The leaves are decurrent, elliptic, oblong or rarely oblong-lance shaped, leaves of main branches and stems 2–6 cm (0.79–2.36 in) long, 0.8–2.3 cm (0.31–0.91 in) wide, margins smooth or toothed. The capitula are usually in a corymb cluster on lateral branches of 45-80 florets and the involucre 0.8–1.4 cm (0.31–0.55 in) long. The pink-purple or red-purple corolla has 5 lobes, 6–7 mm (0.24–0.28 in) long, smooth and usually not glandular. Flowering occurs from July to November and the fruit is dry, one-seeded, 2–2.5 mm (0.079–0.098 in) long, silky with flattened hairs.[2][3][4]
