Astrocaryum farinosum Barbosa Rodrigues 1875

2. Astrocaryum farinosum Barbosa Rodrigues (1875: 21). Type:— BRAZIL. s.l., s.d., Barbosa Rodrigues (“Barb. Rod. hb. Palm. n. 338”—probably destroyed). Neotype [designated by Wessels Boer (1965: 132) as “lectotype”, here corrected]:—Illustration in Barbosa Rodrigues (1903b: Tab. 78). Notes:— Barbosa Rodrigues (1875) described Astrocaryum farinosum from a specimen he collected and deposited in his collection “Barb. Rod. hb. Palm. n. 338”. Based on the literature, his collections from this period were deposited in the herbarium at the Museu Botânico do Amazonas and were subsequently destroyed after the museum closed (Porto 1892, Prance 1971, Mori & Ferreira 1987). Isotypes of the material were not found, and the protologue does not cite other original material. However, a few years after the species was published, Barbosa Rodrigues (1903b) included an illustration of the taxon in his magnum opus Sertum Palmarum Brasiliensium (Fig. 2), which was later designated as the “ lectotype ” by Wessels Boer (1965). This is erroneous designation that is corrected here to neotype under Art. 9.8 and 9.10. Currently, the species is considered valid according to Kahn & Millan (1992), Kahn (2008), and POWO (2024).
