Astrocaryum yauaperyense , Barbosa Rodrigues 1888

5. Astrocaryum yauaperyense Barbosa Rodrigues (1888: 48). Type:— BRAZIL. Prov. Amazonas [Amazonas state]: flum.Yaupery [Jauaperi] ad Rio Negro, s.d., Barbosa Rodrigues (“Herb. Mus. Bot.Amaz.n. 141”—probably destroyed). Neotype [designated by Glassman (1972: 21) as “type”, here corrected]:—Illustration in Barbosa Rodrigues (1903b: Tab. 80A). = Astrocaryum murumuru Martius (1824: 70). Notes:— Astrocaryum yauaperyense is a synonym of Astrocaryum murumuru according to Kahn & Millán (1992) and POWO (2024). In the protologue of A. yauaperyense, Barbosa Rodrigues (1888) only mentioned a single specimen collected from “Rio Jauaperi to Rio Negro” in the Amazonas province and deposited in the Museu Botânico do Amazonas herbarium (Porto 1892, Prance 1971, Mori & Ferreira 1987). Glassman (1972) designated the illustration (Fig. 6) of the species featured in Barbosa Rodrigues’ renowned work Sertum Palmarum Brasiliensium from 1903 as the “type” (Barbosa Rodrigues 1903b). Considering the absence of any other original material found during our search, we confirm Glassman’s designation of the illustration as a neotype.
