Isoetes gardneriana Kunze ex A.Braun. (1862:330)

Taxonomy & Nomenclature

Synonym/s: Isoetes gardneriana Kunze ex Mett. in Fil. Lechl. Fasc. 11: 36 (1859) [used by Hassler (2004-2023)]; Calamaria gardneriana (Kunze ex A.Braun) Kuntze in Revis. Gen. Pl. 2: 828 (1891)

Dispute over taxon authority/year of publication

Most sources cite the author and protologue as Kunze ex A.Braun, Verh. Bot. Vereins Prov. Brandenburg 4: 330 (1862) (e.g. Pereira et al., 2019; POWO, 2023). However, Hassler (2004-2023) cites it as Kunze ex Mett., Fil. Lechl. Fasc. 11: 36 (1859).
