editCalytrix cravenii is an erect, open shrub that typically grows to a height of up to 0.5–2 m (1 ft 8 in – 6 ft 7 in). The leaves are linear, 3–11 mm (0.12–0.43 in) long, 0.3–0.9 mm (0.012–0.035 in) wide on a petiole 0.5–1 mm (0.020–0.039 in) long. The flowers are borne on a peduncle 0.5–0.8 mm (0.020–0.031 in) long with green to light brown bracteoles 2.0–3.5 mm (0.079–0.138 in) long. The floral tube is 2.5–4 mm (0.098–0.157 in) long and has 55 ribs. The sepals are 0.6–1.1 mm (0.024–0.043 in) long and 0.2–8 mm (0.0079–0.3150 in) wide and lack awns. The petals are white, about 6 mm (0.24 in) long and 1.5–1.7 mm (0.059–0.067 in) wide with 18 to 29 white stamens, the longest filaments 4–5 mm (0.16–0.20 in) long. Flowering occurs from early September to early December.[2][3]
