Euphrasia arguta R.Br. (1810:436)
Taxonomy & Nomenclature
Synonym/s: Euphrasia scabra var. arguta (R.Br.) Benth. in A.P.de Candolle, Prodr. 10: 554 (1846)
Conservation Status
Last record: June 1904 (Silcock et al., 2019:SM:19 [as 1904])
Rediscovered in 2008 (Silcock et al., 2019:SM:19)
"First collected by Leichhardt in May 1843, then numerous records through 1890s. Prior to rediscovery in 2008, the species had not been sighted since 1904. Seems to respond to disturbance, and fluctuations in abundance seem likely. Historical loss of habitat for agriculture, but species seems to have been naturally sparse/rare."
(Silcock et al., 2019:SM:19)
