Description

Calytrix platycheiridia is a glabrous shrub that typically grows to a height of up to 45 cm (18 in). Its leaves are overlapping to closely spaced, egg-shaped, 1.5–4.5 mm (0.059–0.177 in) long and 1.0–2.5 mm (0.039–0.098 in) wide and sessile or on a petiole up to 0.25 mm (0.0098 in) long. The flowers are borne on a flattened peduncle 3.5–5 mm (0.14–0.20 in) long with lobes 1.5–3 mm (0.059–0.118 in) long. The floral tube is 2.75–4.0 mm (0.108–0.157 in) long, 0.8–1.0 mm (0.031–0.039 in) wide with eight to ten ribs. The sepals are oblong, 0.3–0.5 mm (0.012–0.020 in) long and 0.7–0.9 mm (0.028–0.035 in) wide. The petals are cream-coloured with a yellow base, egg-shaped to elliptic, 4.25–5.0 mm (0.167–0.197 in) long and 2.25–3.0 mm (0.089–0.118 in) wide, and there are about 35 to 50 yellow stamens in two or three rows. Flowering occurs in October. [2] [3]

Taxonomy

Calytrix platycheiridia was first formally described in 1987 by Lyndley Craven in the journal Brunonia from specimens collected west of Coorow in 1981. [2] [4] The specific epithet (platycheiridia) means 'wide- or broad-glove', referring to the bracteoles. [5]

Distribution and habitat

This species of Calytrix grows sandy soils on low ridges in the Coorow-Watheroo district. [2]

Conservation status

Calytrix platycheiridia is listed as "Priority Two" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, [3] meaning that it is poorly known and from one or a few locations. [6]
