Astrocaryum leiospatha Barbosa Rodrigues 1898

15. Astrocaryum leiospatha Barbosa Rodrigues (1898: 56). Type:— BRAZIL. Prov. Mato Grosso [Mato Grosso state]: s.l., s.d., Barbosa Rodrigues 206 (probably destroyed). Lectotype [designated by Glassman (1972: 18) as “type”, here corrected]:—Illustration in Barbosa Rodrigues (1898: Tab. XIX, Fig. A). = Astrocaryum huaimi Martius (1844: 86). Notes:— Barbosa Rodrigues (1875) described Astrocaryum leiospatha based on a specimen he collected (Barbosa Rodrigues 206) in the former province of Mato Grosso. Possibly, the specimen was deposited in Barbosa Rodrigues’ collection at his residence in the city of Rio de Janeiro (Rodrigues 2012). There are several mentions in the literature that his personal collection was lost (Glassman 1972, Stafleu & Cowan 1976, Batista et al. 2011) due to a major flood that destroyed it in the basement of his house (Buzatto et al. 2011, Stauffer et al. 2016). Given this, Glassman (1972) designated the illustration (Fig. 12) in the protologue as the type of A. leiospatha. Our search found no other original material except for the illustration mentioned above. For this reason, we endorse Glassman’s designation of the Barbosa Rodrigues illustration as the lectotype, following Turland et al. (2018). Currently, the species is considered a synonym of Astrocaryum huaimi according to Kahn & Millan (1992), Henderson et al. (1995), and POWO (2024).
