Goeppertia insignis (W.Bull ex W.E.Marshall) J.M.A.Braga, L.J.T.Cardoso & R. Couto , comb. nov.

Basionym:— Maranta insignis W.Bull ex W.E. Marshall (1902: 63) .

≡ Calathea insignis (W.Bull ex W.E.Marshall) W. Bull (1905: 2) , non Petersen (1890a: 124), nom. illeg.

≡ Calathea lancifolia Boom (1955: 169) .

≡ Goeppertia lancifolia (Boom) Borchsenius & S. Suárez (2012: 631) , nom. inval.

Type:— BRAZIL. Espirito Santo, Linhares, Reserva Florestal da CVRD, 18 December 2001, D. A. Folli 4155 (neotype, RB!, designated here).

Notes:— Marshall (1902) reported the discovery made by William Bull, when he published a diagnosis for Maranta insignis . Bull (1905, 1908) then considered this species as belonging to Calathea , stressing that it was still a relatively new plant in horticulture. However, this specific epithet is unavailable because of the existence of the previously published Calathea insignis Petersen (1890a) . Noting this error, Boom (1955) proposed the new name Calathea lancifolia , under which it is currently known worldwide in ornamental gardens. Boom (1955) also mistakenly cited Maranta insignis as, allegedly, a species of Ward (1906), not Bull ex Marshall (1902). Finally, Borchsenius et al. (2012) transferred Calathea lancifolia to Goeppertia . However, the epithet insignis has priority and is, in fact, available for Goeppertia , allowing transfer of the valid name Maranta insignis (Art. 11.4), as is proposed here. It should be further noted that an incorrect reference to the publication of Calathea lancifolia by Boom (1955) is found in Borchsenius et al. (2012). Thus, the combination proposed by Borchsenius et al. (2012) is not validly published because a full and direct reference to a valid publication of the basionym was not given.
