Diels’ currant bush, Diels’ leptomeria
Taxonomy & Nomenclature
Conservation Status
Missing (Silcock et al., 2019:SM:10 [as 'Possibly extinct']) or Extinct (Humphreys et al., 2019; Albani Rocchetti et al., 2022; Whitby, 2023:3408; Christenhusz & Govaerts, 2024; POWO, 2024)
Last record (disputed): 1844 (Christenhusz & Govaerts, 2024); 1957 (Silcock et al., 2019:SM:10)
