Description
editCalytrix involucrata is a glabrous shrub that typically grows to a height of up to 1 m (3 ft 3 in). Its leaves are spreading to erect, linear to elliptic, 1.75–7.5 mm (0.069–0.295 in) long and 0.7–125 mm (0.028–4.921 in) wide on a petiole 0.4–1 mm (0.016–0.039 in) long. There are stipules up to 0.3 mm (0.012 in) long at the base of the petioles. The flowers are borne in tight clusters with egg-shaped bracts up to 10 mm (0.39 in) long and 5.5 mm (0.22 in) wide on a peduncle 5.5–8 mm (0.22–0.31 in) long with elliptic lobes 3–6 mm (0.12–0.24 in) long. The floral tube has 10 ribs and is 8–12 mm (0.31–0.47 in) long. The sepals are joined at the base, broadly egg-shaped with the narrower end towards the base, 1.0–1.75 mm (0.039–0.069 in) long and 1.75–2.5 mm (0.069–0.098 in) wide with awns up to 12 mm (0.47 in) long. The petals are white, sometimes with a pink tinge, egg-shaped to elliptic, 4.5–7 mm (0.18–0.28 in) long and 2.0–3.5 mm (0.079–0.138 in) wide, and there are 17 to 25 white stamens in a single row. Flowering occurs from August to October.[2][3]
Taxonomy
editCalytrix involucrata was first described in 1928 by John McConnell Black in the Transactions and Proceedings of the Royal Society of South Australia.[4][5] The specific epithet (involucrata) means 'involucrate', or having a ring or rings of bracts around the base of the flowers.[6]
Distribution and habitat
editThis species of Calytrix grows in mallee scrub on sand, mainly in the Eyre and Yorke Peninsulas of South Australia.[2][3]
