Intricate Networks in Nomenclature: Cases of Naming in , , and (Amaranthaceae).

The nomenclatural status and typification of the names , , var. , var. , var. , var. , var. , , , , var. , var. , , var. , , , and , as well as an unnamed β-variety of proposed by , are investigated. Concerning , we document that the type indicated in literature (G00177362) is not a holotype, and that lectotypification is necessary. A specimen from G (G00687638) is here designated as a lectotype. On the level of variety, var. is an earlier legitimate name for var. . Furthermore, Piirainen et al. are incorrect when citing Forsskål's "Salicornia" from Alexandria as "S. virginica Forssk."; it is not a new name and should be cited as S. virginica auct. non L., as published in Forsskål's . Like with numerous other parallel cases in , Forsskål's designation of "Salicornia virginica" for an Arabian plant is to be considered a misapplication of the earlier Linnaean name for an American plant. (a nomen illegitimum of Ungern-Sternberg), was listed as type species of Arthrocnemum by the Names in Current Use project; the basionym, Delile, is here lectotypified and identified as Arthrocaulon meridionale, published by Ramirez et al. Updated synonymies of , , , and are proposed. is an invalid name according to Art. 36.1a of ICN. No original material was found for var. . This paper also refer to lecto- or neotypifications on specimens deposited at BM, G, LINN-HS, LY, MPU, NAP, and PAL, and their current taxonomic positions are suggested in a taxonomic part of the paper.
