Description
Conostylis crassinerva is a rhizomatous, tufted, perennial, grass-like plant or herb up to Шаблон:Cvt in diameter. The leaves are flat, Шаблон:Cvt long and Шаблон:Cvt wide and glabrous or with soft, feather-like hairs. The flowers are arranged in head-like clusters with many flowers on a flowering stalk Шаблон:Cvt long with leaf-like bracts at the base of each flower and 4, shorter bracts at the base of the inflorescence. The perianth is yellow, turning reddish as it ages, Шаблон:Cvt long with loosely woolly hairs on the outside and shortly woolly-hairy inside. The anthers are about Шаблон:Cvt long and the style Шаблон:Cvt long.[1][2]
Taxonomy and naming
Conostylis crassinerva was first formally described in 1961 by John Green in the Proceedings of the Linnean Society of New South Wales from a specimen collected on the top of Mount Lesueur.[2][3] The specific epithet (crassinervia) means "thick-nerved".[4]
In 1987, Stephen Hopper described two subspecies of C. crassinervia and the names are accepted by the Australian Plant Census:
- Conostylis crassinervia subsp. absens Hopper[5] has leaf margins that are not different from the rest of the leaf, with feathery hairs pressed against the surface.[6]
- Conostylis crassinervia J.W.Green subsp. crassinervia[7] has prominent, fibrous, yellowish-brown leaf margins, the rest of the leaf glabrous or with short hairs pressed against the surface.[8]
Distribution and habitat
Subspecies absens is common in heath between the Moore River and the Arrowsmith River in the Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain[6][9] and subsp. crassinervia is common in heaths between Eneabba and Mount Lesueur in the Geraldton Sandplains and Swan Coastal Plain bioregions of south-western Western Australia.[8][10]
