A note on the confusing use of scientific names for this important palm tree Marcelo Mattos Cavallari1 & Marcos Miranda Toledo1,2 Abstract Various scientific names are usually found for the babassu in current literature: mainly Orbignya phalerata and Attalea speciosa, but also O. speciosa and O. martiana, among others. This multiplicity of names leads to great confusion in the scientific community causing mistakes to be successively propagated. This note aims to clarify the problem, reviewing the species nomenclature history since the first description by Martius, in 1826, and reporting the successive name changes which occurred. Consequences of the lumping of four closely related genera, of recent phylogenetic studies and of the last changes in palm classification on the species nomenclature are also briefly discussed. In addition, searching results on scientific names at the main Plant Name Indexes are presented here. As a conclusion, we recommend the adoption of Attalea speciosa Mart ex. Spreng as the most suitable name for the babassu and highlight that a broad taxonomic review of the Attalea group is necessary. Key words: Attalea speciosa, Arecaceae, babassu, Orbignya phalerata, taxonomy. Resumo Na literatura científica atual são encontrados artigos que utilizam diferentes nomes científicos para o babaçu, principalmente Orbignya phalerata e Attalea speciosa, mas também O. speciosa, O. martiana, entre outros. Esta multiplicidade de nomes ocasiona uma grande confusão na comunidade científica que permite a propagação sucessiva de erros. Este artigo de opinião objetiva esclarecer aspectos deste problema, revisando a história da nomenclatura da espécie, desde a primeira descrição por Martius, em 1826, e evidenciando as sucessivas mudanças de nome que ocorreram. São também brevemente discutidas as consequências da fusão dos quatro gêneros relacionados, de recentes trabalhos de filogenia e das últimas mudanças em classificação de palmeiras para a nomenclatura da espécie. Adicionalmente, os resultados de buscas em Índices de Nomes de Plantas são apresentados. Como conclusão, recomendamos a adoção do nome Attalea speciosa Mart ex. Spreng como o mais adequado para o babaçu e frisamos a forte necessidade de uma ampla revisão taxonômica do grupo. Palavras-chave: Attalea speciosa, Arecaceae, babaçu, Orbignya phalerata, taxonomia. Introduction Palm taxonomy and classification has Babassu is a remarkable palm tree shown to be a great challenge. Large fruits, with economic and sociocultural importance inflorescences and leaves make it difficult to (Mesquita 2008), especially in the state of prepare and preserve exsiccatae, resulting in Maranhão. It is associated with “quebradeiras low representation in herbaria (Tomlinson 1979; de coco”, traditional women who break the Balick et al. 1982; Henderson 1995). In addition, coconut to sell the rich-oil seeds. Data records the great variability in morphology, habit and from 2011 indicate that more than 102,000 tons fruit size within species, as well as the occurrence of babassu seeds were commercialized in Brazil of interspecific hybridization, common among (IBGE 2013). The information above leaves no palm trees, further complicates the delimitation doubt about the species in question. However, of species (Henderson 1995). the scientific literature displays discordant According to Pintaud (2008), the taxonomy information in relation to its scientific name. of the genus to which belongs the babassu is 1 Empresa Brasileira de Pesquisa Agropecuária, Embrapa Cocais, Av.

In order which hinder the collection of full material. As to allow a better understanding of the issue, we a result, many extremely abundant species were organize information that is spread out in various described only recently and are still little known. publications and, finally, suggest the adoption of Thus, in the history of babassu nomenclature, a given binomial. descriptions based on incomplete samples are common. Furthermore, the species has been History of the babassu nomenclature described more than once, which took too long Four independent descriptions in the to be realized. Such problems lead to successive nineteenth century start babassu nomenclature: nomenclatural changes. the first description was made by Martius in Moreover, other problem is the adoption of 1826 as Attalea speciosa (Glassman 1999). The different genus concepts by different taxonomists same author described a specimen in Bolivia in (Pintaud 2008). The babassu is considered as 1844 as Orbignya phalerata. Drude described O. either Orbignya or Attalea, depending on each lydiae Drude in Flora Brasiliensis in 1881, based author, a fact discussed here afterwards. Lack on a cultivated material in the Rio de Janeiro of consensus indicates that a comprehensive Botanical Garden; and Barbosa Rodrigues taxonomic review is necessary (Zona 2002; published O. speciosa in 1891 (Glassman 1999). Pintaud 2008), possibly in monographic style. In 1898, Barbosa Rodrigues argued that All the issues above lead to the use of the description of Martius for Attalea speciosa various scientific names for the babassu in was based on an incomplete collection (without recent literature: A. speciosa Mart. ex Spreng. flowers), describing again the species as (Barot et al. 2005; Pintaud 2008; Lorenzi et al. Orbignya martiana (Anderson & Balick 1988; 2010), O. phalerata Mart. (Albiero et al. 2011), Glassman 1999; Pintaud 2008). Later, in 1903, O. speciosa (Mart. ex Spreng.) Barb. Rodr. Barbosa Rodrigues considered that O. martiana (Ferreira 2005; Gama et al. 2007; Soler et al. was the same as O. speciosa, which he had 2007; Vidotto et al. 2007; Reis and Conceição described before (Glassman 1999). 2010), O. martiana Barb. Rodr. (Pavlak et al. To solve distinction problems between 2007; Farias et al. 2011) and O. oleaginosa this species and O. cohune (Mart.) Dahlgren (Silva-Filho et al. 2007). It is also common ex Standl., Burret made another description in to find papers which avoid using the specific 1932, synonymizing O. speciosa, O. martiana epithet, referring to the babassu as Orbignya and A. speciosa under O. barbosiana Burret sp. (Castro et al. 2002; Lima et al. 2006; Silva (Glassman 1999). The other species mentioned & Firmo 2008). (O. phalerata and O. lydiae) would be considered Despite the different cited scientific synonyms later. All of this confusion caused names, all scientific papers above refer to the various scientific names to be used by the same species, as indicated by the geographical scientific community throughout the past two distribution, economic importance and/or other centuries. aspects mentioned in the text. Other palm trees More recently, in 1988, Anderson & are also popularly known as babassu (according Balick studied the taxonomy of the babassu and to Lorenzi et al. 2010: Attalea brasiliensis closely related species. Initially, the authors Glassman, A. brejinhoensis (Glassman) Zona, considered the name O. martiana valid, claiming A. compta Mart., A. pindobassu Bondar and that the oldest combination (O. speciosa) was A. vitrivir Zona). However, these species have invalid. However, comparing the illustrations restricted and/or disjunct distribution range and and descriptions to O. phalerata, described less economic importance, hence, not being from Bolivia in 1844, by Martius, the authors confused with the species in focus. concluded that they were the same species, With so many scientific names, the vast which presents broad geographic distribution. majority of researchers studying the babassu is They concluded that the first proposed name, O. relatively unwilling to dedicate deep study to phalerata, would be more suitable to designate taxonomy papers and search for bibliographical the babassu. updates, adopting the most commonly cited The name O. phalerata was widely names in publications and propagating mistakes. adopted by the scientific community, being Rodriguésia 67(2): 533-538. 2016 The scientific name of the babassu 535 currently used. However, there is a discussion name for the species: Attalea glassmanii Zona about the validity of the genus Orbignya, as (the eighth proposed name for the babassu). presented below. Although correct, this new name was not well The babassu belongs to the subtribe accepted by the scientific community. Authors Attaleinae (Dransfield & Uhl 1986). Several such as Govaerts & Dransfield (2005) preferred genera compose this subtribe, and Dransfield et to keep A. speciosa because of its traditional al.

A group of related genera, known as “Attalea Alliance” (Glassman 1977), can be recognized Recent publications and the advent within Attaleinae: Attalea (Humboldt et al. of molecular biology 1816), Maximiliana (Martius 1826), Orbignya Dransfield et al.
