Reinstatement of Thysanotus elatior R.Br. (Asparagaceae)

Abstract

Thysanotus elatior R.Br. (Asparagaceae) is reinstated, described, lectotypified and compared with putatively related species. The species is restricted to the Top End of the Northern Territory and the Kimberley of Western Australia but was previously confused with T. banksii R.Br., a Queensland species. Notes are provided on the distribution, habitat, phenology, conservation status and affinities of Thysanotus elatior. Thysanotus chinensis Benth. also occurs in north-western Australia and a key to distinguish the two is provided. The application of the names Thysanotus elatior and T. tuberosus R.Br. to material there is also discussed.
