9. Astrocaryum princeps var. sulphureum Barbosa Rodrigues (1888: 50). Type:—not designated and no specimens cited. Neotype [designated by Glassman (1972: 20) as “type”, here corrected]:—Illustration in Barbosa Rodrigues (1903b: Tab. 80B). = Astrocaryum tucuma. Notes:—In his original publication of Astrocaryum princeps var. sulphureum, Barbosa Rodrigues (1888) did not designate a type or cite any other original material. However, in a later work, Barbosa Rodrigues (1903b) included an illustration of this variety (Fig. 6), which was designated as the “type” by Glassman (1972). We recognize this illustration as a neotype following the guidelines outlined by Turland et al. (2018).
