Conostylis androstemma

Conostylis androstemma has green, hairless, terete leaves which are 10 to 30 cm long and about 1 mm in diameter. The flower has stems (pedicels) that are less than 1 mm long, and bracts which are about 5 mm long and 2 mm wide.[4] The cream to pale yellow perianth is hairy and radially symmetrical[5] It is 30–50 mm long with a tube which is usually straight. The lobes are not reflexed and are 15 to 25 mm long.[4] There are six stamens, all at the one level.[5] The filaments are 8–17 mm long and the yellow anthers 3–5.5 mm long[4] and without an appendage.[5] The style is 30–50 mm long.[4]

It flowers from May to August.[5]

The plant resprouts from its rhizomes, after fire.[4]

It is easily distinguished from Conostylis argentea by its terete hairless leaves.[4]

It grows in lateritic gravel and yellow sand on screes and hilltops,[5]

It occurs in south-western Western Australia from Kalbarri National Park to Perth and York.[4]

Originally named Androstemma junceum and described by John Lindley in 1840 in A Sketch of the Vegetation of the Swan River Colony,[6][7] the species was assigned to the genus Conostylis by botanist Ferdinand von Mueller in 1873 in Fragmenta Phytographiae Australiae and renamed Conostylis androstemma.[1][2]
