3. Astrocaryum princeps Barbosa Rodrigues (1875: 22) .

Type:— BRAZIL. s.l., s.d., Barbosa Rodrigues (“Barb. Rod. hb. Palm. n. 219”—probably destroyed) . Neotype [designated by Wessels Boer (1965: 126) as “lectotype”, here corrected]:—Illustration in Barbosa Rodrigues (1903b: Tab. 73) .

= Astrocaryum tucuma Martius (1824: 77) .

Notes:— Astrocaryum princeps , included as a synonym of Astrocaryum tucuma by Kahn & Millan (1992), Henderson et al. (1995) and Kahn (2008), was described by Barbosa Rodrigues (1875) based on a specimen he collected and deposited in his collection “Barb. Rod. hb. Palm.” The specimen was deposited in the Museu Botânico do Amazonas herbarium and likely 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 any other original material. However, a few years after the species was published, Barbosa Rodrigues (1903b) included an illustration of the taxon ( Fig. 3 ), which was later designated as the “ lectotype ” by Wessels Boer (1965). Here, we recognize this illustration as a neotype (see Art. 9.8 and 9.10).
