Indigofera efoliata F.Muell. (1883:55)
Leafless indigo
Taxonomy & Nomenclature
Synonym/s: Anil efoliata (F.Muell.) Kuntze in Revis. Gen. Pl. 2: 939 (1891)
Conservation Status
Missing (Silcock et al., 2019:SM:6 [as Possibly extinct]) or Extinct (POWO, 2023; Christenhusz & Govaerts, 2024)
Last record (disputed): 1955 (August or later) (Silcock et al., 2019:SM:6); 1998 (Christenhusz & Govaerts, 2024)
"Targeted surveys undertaken in 1997-8; no plants found... Two records contain precise locality details; both have been either heavily grazed or cleared; one site is now very weedy. Record on NSW BioNet from 1998 is observational, and no further details can be found. A couple more localities to be searched to ensure all known and predicted sites covered."
(Silcock et al., 2019:SM:6)
Distribution & Habitat
Dubbo to Guerie, New South Wales, Australia
"From Dubbo to Guerie, stony ironstone rises in dry sclerophyll forest"
(Silcock et al., 2019:SM:6)
