Taxonomic remark From Cleal & Thomas, 2018: [as nom. illeg. in Brogniart, 1822] ... Brongniart (1822a) also included two new species within the genus: “Sagenaria coelata” Brongniart, 1822a and “Sagenaria ophiurus” Brongniart, 1822a. However, these latter two names were probably not validly published here as they were unaccompanied by diagnoses; an illustration with a close-up of the shoot was given for S. coelata but this does not show the diagnostic characters sufficiently to count as an “illustration with analysis” to validate the species epithet under ICN, Art. 38.7–9. The only previous proposal to typify Sagenaria was by Andrews (1955) with “S. coelata” but this has to be rejected as that species was not validly published in 1822. A lectotype for Sagenaria must therefore be selected from the species listed by Sternberg (1820) under Lepidodendron sect. Lepidotae, as Brongniart was clearly (albeit indirectly) including them within the genus (ICN, Arts 10.2, 10.3). In order to simplify the situation, we designate here Lepidodendron aculeatum Sternberg, 1820 as lectotype of Sagenaria – it is conspecific with one of the specimens illustrated by Brongniart (1822a: pl. 12, fig, 6 ‒ as “S. coelata”).
