8. Astrocaryum princeps var. flavum Barbosa Rodrigues (1888: 50) .

Type:—not designated and no specimens cited. Neotype [designated by Glassman (1972: 19) as “type”, here corrected]:—Illustration in Barbosa Rodrigues (1903b: Tab. 80C) .

= Astrocaryum tucuma .

Notes:— Barbosa Rodrigues (1888) did not designate any type and did not cite any other original material in the protologue of Astrocaryum princeps var. flavum . However, the naturalist included an illustration of this taxon (Fig. 6) in his work Sertum Palmarum Brasiliensium ( Barbosa Rodrigues 1903) some years after the original publication. Glassman (1972) designated this illustration as the “type” for the variety. Here, we recognize this illustration as a neotype.
