Astrocaryum echinatum Barbosa Rodrigues 1898

13. Astrocaryum echinatum Barbosa Rodrigues (1898: 51). Type:— BRAZIL. Prov. Mato Grosso [Mato Grosso state]: Serra da Chapada, s.d., Barbosa Rodrigues 221 (probably destroyed). Lectotype [designated by Glassman (1972: 16) as “type”, here corrected]: Illustration in Barbosa Rodrigues (1898: Tab. XVII). Notes:— Barbosa Rodrigues (1898) described Astrocaryum echinatum based on a specimen he collected (Barbosa Rodrigues 221), which was likely deposited in his personal collection at his residence in the city of Rio de Janeiro (Rodrigues 2012). According to Buzatto et al. (2011) and Stauffer et al. (2016), this collection was destroyed during a bad flood in the city. The only remaining original material consists of an illustration of the species in the protologue (Fig. 10), which was later designated as the “type” by Glassman (1972). Considering no other original material was discovered during our thorough investigation of the herbaria, we recognize Glassman’s designation of the illustration as a lectotype, following the Code of Nomenclature for algae, fungi, and plants (Turland et al. 2018). Currently, this species is considered valid according to Kahn & Millan (1992), Kahn (2008), and POWO (2024).
