Hemigenia obtusa Benth. (1848:567)
Blunt-leaved hemigenia
Taxonomy & Nomenclature
"Known from four collections between 1844 and 1892; in her unpublished conspectus of Hemigenia, Barbara Rye included H. obtusa in the H. incana complex. This is difficult taxonomic terrain; its status should be considered problematic until species boundaries within that complex are resolved following future revision."
(Silcock et al., 2019:SM:1)
Conservation Status
Extinct (Humphreys et al., 2019; Christenhusz & Govaerts, 2024; POWO, 2024) or taxonomically problematic (Silcock et al., 2019:SM:1)
Last record: 1879 (Christenhusz & Govaerts, 2024); 1892 (Silcock et al., 2019:SM:1)
