74108795FE3E5A1AFF564AA3FAC06ED8.taxon	discussion	Notes: — Barbosa Rodrigues (1875) described Astrocaryum acanthopodium from a specimen he collected on the Trombetas River, in Pará State, Brazil. Based on substantial historical data, the specimen was deposited in the Museu Botânico do Amazonas herbarium but later destroyed after the museum closed (Porto 1892, Prance 1971, Mori & Ferreira 1987). Isotypes of the material were not found, and the protologue does not cite any other original material. However, a few years after the species was published, Barbosa Rodrigues (1903 b) published an illustration of the taxon (Fig. 1), which was initially designated as “ lectotype ” by Wessels Boer (1965). Here, we recognize this illustration as a neotype, in accordance with Art. 9.8 and 9.10 of Turland et al. (2018). Currently, the species is considered a synonym of Astrocaryum paramaca, according to Kahn & Millan (1992), Henderson et al. (1995), and POWO (2024).	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

74108795FE3E5A1AFF5648C7FF5668D0.taxon	discussion	Notes: — Barbosa Rodrigues (1875) described Astrocaryum farinosum from a specimen he collected and deposited in his collection “ Barb. Rod. hb. Palm. n. 338 ”. Based on the literature, his collections from this period were deposited in the herbarium at the Museu Botânico do Amazonas and were subsequently destroyed after the museum closed (Porto 1892, Prance 1971, Mori & Ferreira 1987). Isotypes of the material were not found, and the protologue does not cite other original material. However, a few years after the species was published, Barbosa Rodrigues (1903 b) included an illustration of the taxon in his magnum opus Sertum Palmarum Brasiliensium (Fig. 2), which was later designated as the “ lectotype ” by Wessels Boer (1965). This is erroneous designation that is corrected here to neotype under Art. 9.8 and 9.10. Currently, the species is considered valid according to Kahn & Millan (1992), Kahn (2008), and POWO (2024).	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

Isotypes of the material were not found, and the protologue does not cite any other original material. However, a few years after the species was published, Barbosa Rodrigues (1903 b) included an illustration of the taxon (Fig. 3), which was later designated as the “ lectotype ” by Wessels Boer (1965).

74108795FE305A14FF564B83FB616FA0.taxon	discussion	Notes: — Astrocaryum caudescens is among the many synonyms of Astrocaryum tucuma (Kahn & Millan 1992, Henderson et al. 1995, POWO 2024). In the protologue, Barbosa Rodrigues (1875) cited a specimem deposited in his collection “ Barb. Rod. hb. Palm. ”. The literature also indicates that the “ Barb. Rod. hb. Palm. ” collection from that time was deposited in the Museu Botânico do Amazonas herbarium (Porto 1892, Prance 1971, Mori & Ferreira 1987). In our search for original material, we found no palm specimen of the taxon collected by Barbosa Rodrigues. Considering the lack of other original material found during our search, we recommend retaining the typification made by Glassman (1972) of the illustration in Barbosa Rodrigues’ subsequent publication (Figs. 4 and 5) called “ Sertum Palmarum ’’ (Barbosa Rodrigues 1903 b). We now recognize the illustration as a neotype.

74108795FE305A13FF564C0AFC566C3C.taxon	discussion	Notes: — All four varieties of Astrocaryum princeps (var. aurantiacum, var. flavum, var. sulphureum, and var. vitellinum) described by Barbosa Rodrigues are synonyms of Astrocaryum tucuma (Kahn & Millán 1992, POWO 2024). In the case of Astrocaryum princeps var. aurantiacum, Barbosa Rodrigues (1888) did not designate a type, and no other original material is cited in the protologue. Glassman (1972) designated an illustration (Fig. 7) published decades later by Barbosa Rodrigues (1903 b) as the type for this variety. Given that we did not find other original material of this taxon, it is essential to confirm Glassman’s designation of the Barbosa Rodrigues illustration as the neotype, following the Code of Nomenclature for algae, fungi, and plants (Turland et al. 2018).	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

74108795FE305A14FF564E03FB7E6B9C.taxon	discussion	Notes: — Barbosa Rodrigues (1888) described Astrocaryum sociale based on a specimen collected in the Amazonian region of Brazil (“ Herb. Mus. Bot. Amaz. n. 567 ”). The type specimen was obtained from Igarapé Tarumá-Mirim, near the city of Manaus, by the Rio Negro, and was also deposited in the herbarium at the Museu Botânico do Amazonas (Porto 1892, Prance 1971, Mori & Ferreira 1987). Wessels Boer (1965) designated an illustration (Fig. 7) published decades later by Barbosa Rodrigues (1903 b) as the lectotype of this species due to the absence of the specimen. Our extensive investigations failed to locate any other original material of this taxon. For this reason, following the Code of Nomenclature for algae, fungi, and plants (Turland et al. 2018), we uphold Wessels Boer’s designation of Barbosa Rodrigues’ illustration as the neotype, correcting the use of the term lectotype according to Art. 9.10.	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

In the protologue of A. yauaperyense, Barbosa Rodrigues (1888) only mentioned a single specimen collected from “ Rio Jauaperi to Rio Negro ” in the Amazonas province and deposited in the Museu Botânico do Amazonas herbarium (Porto 1892, Prance 1971, Mori & Ferreira 1987). Glassman (1972) designated the illustration (Fig. 6) of the species featured in Barbosa Rodrigues’ renowned work Sertum Palmarum Brasiliensium from 1903 as the “ type ” (Barbosa Rodrigues 1903 b).

Despite A. arenarium being considered valid according to POWO (2024), it is often categorized as dubious or potentially extinct (Lorenzi et al. 2010). About the type, as with all other previously reported species, the specimen indicated in the protologue of Astocaryum arenarium was probably destroyed. Based on substantial historical information, the material was deposited in the personal collection of Barbosa Rodrigues, which was subsequently lost during a bad flood in the city of Rio de Janeiro (Glassman 1972, Stafleu & Cowan 1976, Batista et al. 2011, Buzatto et al. 2011, Rodrigues 2012, Stauffer et al. 2016). Consequently, the only remaining original material is an illustration (Fig. 11) of the species in the protologue (Barbosa Rodrigues 1898), which Glassman designated as the type.

74108795FE2B5A0FFF5649AAFB416929.taxon	discussion	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).	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

74108795FE2B5A0EFF564D9EFA2F6C74.taxon	discussion	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).	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

74108795FE2D5A09FF564D7FFCFA6AE8.taxon	discussion	Notes: — The taxonomic identity of this species is still uncertain; it falls into the category of names not yet attributed to a known taxon (POWO 2024, Tropicos 2024, Vianna 2024). The protologue of A. burity (Barbosa Rodrigues 1903 b) consists of a brief diagnostic description but does not indicate the type specimen. However, Barbosa Rodrigues included an original illustration (Fig. 9) in the protologue, which Glassman (1972) designated as the “ type ” due to the absence of other original material. To adhere to the International Code of Nomenclature (Turland et al. 2018), we propose upholding Glassman’s designation as the lectotype for this species.	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

74108795FE2D5A09FF5649A7FBD06915.taxon	discussion	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).

74108795FE2D5A09FF564F93FAA66B40.taxon	discussion	Notes: — Astrocaryum kewense stands out for being the only Astrocaryum species described by Barbosa Rodrigues that still has specimens remaining today. The type materials were collected by Auguste Glaziou (the gathering Glaziou 22279), a renowned French researcher, in the former province of Goyaz, while he was studying the location for the new capital of the country for the Brazilian government (Barbosa Rodrigues 1903). Glaziou deposited one specimen of this gathering in the Kew Herbarium (K). This only specimen of the K herbarium was cited by Barbosa Rodrigues in the protologue of A. kewense (Barbosa Rodriugues 1903 b). Following the guidelines of McNeill (2014), we established this specimen as the holotype of A. kewense. In our investigations, we also found isotypes in the Missouri Botanical Garden Herbarium (MO) and Muséum National d’Histoire Naturelle Herbarium (P). The taxonomic identity and validity of this species are currently considered uncertain, according to POWO (2024) and Vianna (2024).	en	Lima, Gustavo Pereira, Amorim, Gabriela, Jr, Eduardo Bezerra De Almeida (2024): An overview of Astrocaryum (Bactridinae, Arecaceae) types from Brazil described by João Barbosa Rodrigues.

In his original Astrocaryum leiospatha var. subulosum publication, Barbosa Rodrigues (1888) did not designate a type or provide a set of specimens. However, he included an illustration (Fig. 12) of this variety in the protologue, which was later designated as the “ type ” by Glassman (1972). This illustration is here recognized as a lectotype following the guidelines by Turland et al. (2018).
