Description

Calytrix islensis is a mostly glabrous shrub that typically grows to a height of up to 2 m (6 ft 7 in). Its leaves are elliptic to egg-shaped with the narrower end towards the base, 2.0–3.5 mm (0.079–0.138 in) long, 1.0–1.2 mm (0.039–0.047 in) wide and sessile or on a petiole up to 0.5 mm (0.020 in) long. There are stipules up to 0.2 mm (0.0079 in) long at the base of the petiole. The flowers are borne in clusters on a peduncle 8–9 mm (0.31–0.35 in) long with egg-shaped lobes 6–7 mm (0.24–0.28 in) long. The floral tube is mostly free from the style, 8–10 mm (0.31–0.39 in) and has 10 ribs. The sepals are fused at the base, with more or less round lobes 2.5–3.0 mm (0.098–0.118 in) long and 2.8–3.5 mm (0.11–0.14 in) long, with an awn long up to 11 mm (0.43 in) long. The petals are white with a yellow base, elliptic to lance-shaped, 6.5–8 mm (0.26–0.31 in) long and 3–4 mm (0.12–0.16 in) wide, and there are about 65 to 70 yellow stamens in two or three rows. Flowering occurs in September and October.^[2][3]
