Hypocalymma linifolium is a low, spreading shrub that typically grows to a height of 50–70 cm (20–28 in). Its leaves are sessile, narrowly egg-shaped to almost linear, 12–14 mm (0.47–0.55 in) long, 2–4 mm (0.079–0.157 in) wide and glabrous with grooves along the midvein and a short point on the tip. The flowers are in clusters of 3 to 5 and are more or less sessile with bracts 1–2 mm (0.039–0.079 in) long and bracteoles 1.5–2 mm (0.059–0.079 in) long. The sepals are 1.3–1.6 mm (0.051–0.063 in) long and the petals are bright yellow, 2.5–3 mm (0.098–0.118 in) long. There are 22 to 41 stamens shortly joined at the base, the longest filaments about 3 mm (0.12 in) long. Flowering occurs in August and September and the fruit is 2.5–3.0 mm (0.098–0.118 in) long. [4] [3] Hypocalymma linifolium is a hybrid between Hypocalymma angustifolium and H. lateriticola . [5]
Hypocalymma linifolium was first formally described in 1862 by Nikolai Turczaninow in the Bulletin de la Société Impériale des Naturalistes de Moscou. [6] [7] The specific epithet (linifolium) means 'thread-leaved'. [8]
