Also known as <em>pau-brasil<\/em>, the tree lent its name to its homeland. Now the tree officially has a new scientific name and has become the first and only species of a new genus. One of the conclusions reached by researchers from Canada, Switzerland, the United Kingdom, and Brazil who conducted phylogenetic analyses of DNA samples from 173 of the 205 species belonging to the <em>Caesalpinia<\/em> group was that the brazilwood tree is so unique that it merits its own genus (<em>Phytokeys, <\/em>October 12, 2016<em>)<\/em>. Originally named <em>Caesalpinia echinata <\/em>by Lamarck in 1785, the species has now been rechristened <em>Paubrasilia echinata<\/em>. According to the authors of the study \u2013 which include plant taxonomist Luciano Paganucci de Queiroz, from the State University of Feira de Santana (UEFS) in Bahia State \u2013 the genetic material and morphological traits of <em>pau-brasil<\/em> render the tree distinct enough to warrant its own generic rank. In their paper, the researchers propose a new generic classification for the entire <em>Caesalpinia<\/em> group, previously divided into 21 genera. The new proposal classifies species into 27 genera, one of which is provisional (<em>Ticanto<\/em>).<\/p>\n","protected":false},"excerpt":{"rendered":"Pau-brasil has become the first and only species of a new genus of trees","protected":false},"author":475,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[168],"tags":[213],"coauthors":[785],"class_list":["post-237802","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-botany"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/237802","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=237802"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/237802\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=237802"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=237802"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=237802"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=237802"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
