Description
Thryptomene calcicola is an erect, sometimes spreading shrub that typically grows to a height of 0.3–1.8 m (1 ft 0 in – 5 ft 11 in). Its leaves are directed upwards, linear, 5–9 mm (0.20–0.35 in) long and 0.4–0.8 mm (0.016–0.031 in) wide on a petiole 0.1–0.4 mm (0.0039–0.0157 in) long. The flowers are arranged raceme-like in groups of four to fifteen on a peduncle 0.6–1 mm (0.024–0.039 in) long with egg-shaped bracteoles 2.2–3 mm (0.087–0.118 in) long and that remain until the fruit is shed. The flowers are 7–8 mm (0.28–0.31 in) in diameter with glossy, egg-shaped sepals 1.0–1.2 mm (0.039–0.047 in) long. The petals are pinkish-mauve, 2.5–3 mm (0.098–0.118 in) long and there are usually ten stamens. Flowering occurs from June to late October.[2]
Taxonomy
Thryptomene calcicola was first formally described in 2014 by Barbara Lynette Rye in the journal Nuytsia from specimens collected by Malcolm Eric Trudgen in Kalbarri National Park in 2002.[2][3] The specific epithet (calcicola) means "lime-inhabitant", referring to the limestone habitat of this species.[2]
Distribution and habitat
This thryptomene only occurs in a small area of Kalbarri National Park where it grows in Acacia shrubland.[2][4]
Conservation status
Thryptomene calcicola is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife,[4] meaning that it is poorly known and from only one or a few locations.[5]
