Scientific name: Deyeuxia lawrencei
Deyeuxia lawrencei was an erect, hairless, perennial grass 5060 cm high. The stems were ribbed, slender and thread-like (but quite stout and stiff). The leaf blades were flat or loosely in-rolled when dry. They were finely ribbed and rough on the leaf margins and ribs of the lower leaf surface (up to 12 cm long and 4 mm wide). The sheaths surrounding the base of the leaves were ribbed and open (the uppermost sheaths were fairly loose) (Curtis & Morris 1994; Tas. DPIWE 2003).
Deyeuxia lawrencei was endemic to Tasmania and was known only from the type specimen collected around 1831. The location of this collection is unknown, although it was possibly from the Launceston area (Curtis & Morris 1994; TPLUC 1996).
Deyeuxia lawrencei occurred in dry sclerophyll forest habitat (Curtis & Morris 1994; TPLUC 1996).
The reasons for the decline and extinction of Deyeuxia lawrencei are unknown. It was reported that the species could persist through fire and grazing (TPLUC 1996); therefore, these two potential threats were unlikely to have been a significant factor in its disappearance.
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
