2.3. Aerva lanata (L.) Juss. ex Schult. in Roemer & Schultes, Syst. Veg. 5: 564. 1819

≡ Achyranthes lanata L., Sp. Pl.: 204. 1753 ≡ Illecebrum lanatum (L.) L., Mant. Pl.: 344. 1771 ≡ Ouret lanata (L.) Kuntze, Revis. Gen. Pl. 2: 544. 1891.

Lectotype (designated here): — [icon] “ CHENOPODIUM incanum racemosum , folio majore, minori opposito ” in Burman 1737: t. 26, fig. 1 (image of the lectotype available at https://www.biodiversitylibrary.org/item/14648#page/105/mode/1up).

Revised typification of Achyranthes lanata :— Iamonico (2014: 406) described the protologue of the Linnaean name Achyranthes lanata by citing correctly Burman’s reference to the illustration “t. 26, f. 1” ( Burman 1737, Linnaeus 1753: 204). However, in the taxonomic treatment, Iamonico (2014: 407) indicated Burman’s “AMARANTUS spicatus Zeylanicus, foliis obtusis, &c in Burman 1737: t. 5, fig. 3” as the lectotype of the name (also publishing a figure; Iamonico 2014: Fig. 1 ; image available at https://www.biodiversitylibrary.org/item/14648#page/31/mode/1up). This latter Burman’s polynomial, however, is part of the original for A. aspera L. var. indica L. (Iamonico 2014: 405). Burman’s “t. 26, f. 1”, reported by Linnaeus (1753: 204) for A. lanata , actually refers to “ CHENOPODIUM incanum racemosum , folio majore, minori opposito ” which relevant illustration is designated here as the lectotype of A. lanata , thereby revising the inadvertently wrong typification by Iamonico (2014: 407).
