Abstract
We here describe Machaerina ascendens R.L.Barrett & K.L.Wilson as a new species from swamps within forests in the far south-west of Western Australia. The new species is readily identifiable by its scrambling habit and compressed, multi-noded culms, features which separate it from all other Australian species. The clearly distichous glumes, few hypogynous scales fused at the base into a ring and prominently stipitate nutlets are also unusual features in Machaerina Vahl. Machaerina ascendens is highly range-restricted by its specific habitat and appears to qualify for listing as Endangered. Study of all names applicable to the current concept of Machaerina revealed an earlier name for the eastern Australian species Machaerina nuda (Steud.) J.Kern, and a new combination is provided here for Schoenus abbreviatus Nees as Machaerina abbreviata (Nees) R.L.Barrett & K.L.Wilson.
期刊介绍：
Manuscripts submitted for publication in TELOPEA are published online, after peer review and acceptance by the TELOPEA Editorial Committee and when final editorial formatting has been completed. The journal specialises in plant systematics and phylogeny. The geographic scope of the journal encompasses Australia, Malesia, Melanesia, Micronesia, and Polynesia. The suitability of a work for the journal depends on the topic and the region of origin, generally the narrower the focus of the manuscript the closer to New South Wales must be its geographic focus.
As a general guide, we will consider:
1) revisionary treatments and other substantial bodies of work from any of the regions mentioned above.
2) new species from any Australian state.
3) new country records for Australia from any state.
4) new state records from New South Wales only.
However, we aim to support botanical research across the broader Australasian and Pacific region, and will consider submissions on their merit.
Generally we will not consider extraterritorial new country records, or single lectotypification papers unless they pertain to New South Wales taxa, or have significant bearing on the Australian flora.
