Description
editThryptomene podantha is an often widely-spreading shrub that typically grows to a height of 0.3–1.5 m (1 ft 0 in – 4 ft 11 in). Its leaves are upward-pointing, overlapping, and egg-shaped with the narrower end towards the base, 2.5–6.5 mm (0.098–0.256 in) long and 1.3–1.7 mm (0.051–0.067 in) wide on a petiole 0.4–0.7 mm (0.016–0.028 in) long. The flowers are arranged in racemes of more or less spherical groups of between two and seven flowers. Each flower is on a peduncle 0.5–1.5 mm (0.020–0.059 in) long with leaf-like bracteoles 1.0–1.3 mm (0.039–0.051 in) long that fall as the flower develops. The flowers are 4.5–5.5 mm (0.18–0.22 in) wide with pink, petal-like sepals 0.5–1.0 mm (0.020–0.039 in) long and 0.8–1.5 mm (0.031–0.059 in) wide. The petals are also pink, 2.0–2.4 mm (0.079–0.094 in) long and there are ten stamens. Flowering occurs from June to September.[2]
Taxonomy
editThryptomene podantha was first formally described in 2014 by Barbara Lynette Rye and Malcolm Eric Trudgen in the journal Nuytsia from specimens collected by Donald Bruce Foreman near Yuna in 1984.[2][3] The specific epithet (podantha) means "foot-flowered", referring to the pedicillate flowers and fruit.[2]
Distribution and habitat
editThis thryptomene grows in open shrubland from near Shark Bay to Wandana Nature Reserve near Geraldton in the Carnarvon, Geraldton Sandplains and Yalgoo biogeographic regions of Western Australia.[2][4]
Conservation status
editThryptomene podantha is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[4]
