Quaqua arenicola arenicola (N.E.Br.) Plowes (1994:98)
Taxonomy & Nomenclature
Synonyms: Caralluma arenicola N.E.Br. in W.H.Harvey & auct. suc. (eds.), Fl. Cap. 4(1): 883 (1909); Quaqua armata subsp. arenicola (N.E.Br.) Bruyns in Bradleya 1: 67 (1983); Ceropegia arenicola (N.E.Br.) Bruyns in S. African J. Bot. 112: 418 (2017)
Conservation Status
Rediscovered [by implication] (Victor, 2020)
This taxon was historically considered Extinct by at least one source who treated it as a binomial (fide Humphreys et al., 2019). It was indeed treated as Extinct by (Hall et al., 1980; fide Victor, 2020), but is today considered of Least Concern (Victor, 2020), and thus was by implication Rediscovered at some point.
