Astrocaryum sociale Barbosa Rodrigues 1888

6. Astrocaryum sociale Barbosa Rodrigues (1888: 48). Type:— BRAZIL. Prov. Amazonas [Amazonas state]: Igarapé Tarumá-mirí [Tarumá-mirim] in Rio Negro, s.d., Barbosa Rodrigues (“Herb. Mus. Bot. Amaz. n. 567”—probably destroyed). Neotype [designated by Wessels Boer (1965: 132) as “lectotype”, here corrected]:—Illustration in Barbosa Rodrigues (1903b: Tab. 79A). Notes: — Barbosa Rodrigues (1888) described Astrocaryum sociale based on a specimen collected in the Amazonian region of Brazil (“Herb. Mus. Bot. Amaz. n. 567”). The type specimen was obtained from Igarapé Tarumá-Mirim, near the city of Manaus, by the Rio Negro, and was also deposited in the herbarium at the Museu Botânico do Amazonas (Porto 1892, Prance 1971, Mori & Ferreira 1987). Wessels Boer (1965) designated an illustration (Fig. 7) published decades later by Barbosa Rodrigues (1903b) as the lectotype of this species due to the absence of the specimen. Our extensive investigations failed to locate any other original material of this taxon. For this reason, following the Code of Nomenclature for algae, fungi, and plants (Turland et al. 2018), we uphold Wessels Boer’s designation of Barbosa Rodrigues’ illustration as the neotype, correcting the use of the term lectotype according to Art. 9.10.
