12. Astrocaryum manaoense Barbosa Rodrigues (1891a: 105) View in CoL .

Type:— BRAZIL. Prov. Amazonas [Amazonas state]: in Manáos [Manaus] ad Rio Negro , s.d., Barbosa Rodrigues (“Herb. Mus. Bot. Amaz. n. 701”—probably destroyed) . Neotype [designated by Glassman (1972: 18) as “type”, here corrected]:—Illustration in Barbosa Rodrigues (1903b: Tab. 71A) .

= Astrocaryum tucuma .

Notes:— Astrocaryum manaoense was treated as a synonym of Astrocaryum tucuma by Kahn & Millan (1992), Henderson et al. (1995), and POWO (2024). In the protologue, Barbosa Rodrigues (1888) mentioned a single specimen that was collected in the city of Manaus and deposited in the Museu Botânico do Amazonas herbarium ( Porto 1892, Prance 1971, Mori & Ferreira 1987). However, the original specimen that served as the basis of the description is believed to have been lost after the herbarium closed at the end of the 19 th century, as noted by Prance (1971), Mori & Ferreira (1987), Rodrigues (2012), Lopes & Sá (2016), and Lopes (2022). Glassman (1972) designated the illustration ( Fig. 9 View FIGURE 9 ) in Barbosa Rodrigues’ renowned work Sertum Palmarum Brasiliensium from 1903 as the “type” ( Barbosa Rodrigues 1903b ). Considering no other original material was found during our search, we confirm Glassman’s designation of the illustration as a neotype.
