17. Astrocaryum giganteum Barbosa Rodrigues (1902: 82) .

Type:—not designated and no specimens cited. Lectotype [designated by Glassman (1972: 20) as “type”, here corrected]: Illustration in Barbosa Rodrigues (1902: Tab. X, Fig. C) .

Notes:—The protologue of A. giganteum (Barbosa Rodrigues 1902) lacks any indication of the type or other specimens. However, an original illustration by Barbosa Rodrigues (Fig. 13) is in the article. This illustration was designated as the “type” by Glasmann (1972). Here, we confirm Glassman’s designation of the illustration as a lectotype, following the guidelines outlined by Turland et al. (2018). Currently, the species is considered valid according to Kahn (2008), Lorezin et al. (2010), POWO (2024), and Vianna (2024).
