Conostylis deplexa is a rhizomatous, tufted or solitary perennial, grass-like plant or herb that typically grows to high. The leaves are flat, long and wide and glabrous, apart from bristly hairs on the edges. The flowers are arranged in groups of 10 to 20 on a hairy flowering stalk long with bracts long at the base. The perianth is yellow, long with more or less equal lobes long. The anthers are about long and the style long. Flowering occurs from early September to late October.[1] [2]
Conostylis deplexa was first formally described in 1982 by John Green in the journal Nuytsia from a specimen collected he collected on the Ravensthorpe - Jerramungup road in 1975.[3] The specific epithet (deplexa) means "embracing" or "clasping", referring to the bristles on the leaf margins.[4]
This species of conostylis grows in open shrub mallee, low, closed heath or low open woodland between the Stirling Range and the northern parts of the Fitzgerald River National Park in the Esperance plains and Mallee bioregions of south-western Western Australia.
