Plagiobothrys glaber (Gray) I.M.Johnst. (1923:77)
Hairless popcorn(-)flower, Glabrous allocarya
Taxonomy & Nomenclature
Synonyms: Lithospermum glabrum A.Gray in Proc. Amer. Acad. Arts 17: 227 (1882); Allocarya glabra (A.Gray) J.F.Macbr. in Proc. Amer. Acad. Arts 51: 543 (1916); Allocarya salina Jeps. in Fl. W. Calif.: 442 (1901)
Conservation Status
Last record: 1955 (NatureServe, 2024)
Rediscovered by Olive Zappacosta on 7 May 2001 (cf. Calflora, 2024; contra Rejmánek, 2018)
Rejmánek (2018) states "Rediscovered by Randall Morgan in the Alameda Co. in 2002 and 2003", but Calflora (2024) has an observation record by Olive Zappacosta on 7 May 2001, predating their observation record by Randall Morgan of 24 April 2003. Thus even though Calflora (2024) do not explicitly state that the species was rediscovered, it provides the precise date.Still listed as Extinct by (NatureServe, 2024).
