The genus (type species ) was established in 1978 by Hennen and Ono and named after the Brazilian Cerrado biome. The holotype collected in Planaltina, Federal District, Brazil, belonged to the first rust fungus reported on palms (Arecaceae). For decades, the status of as a distinct genus has been regarded as doubtful, representing a synonym of (Uropyxidaceae) starting with the second edition of the in 1983. Our molecular phylogenetic analyses, as well as our morphological investigations, allowed us to reject this synonymy, leading to the reinstatement of within the Pucciniaceae. , together with morphologically similar genera such as the newly established with two species ( and ) infecting araceous hosts, the fern rust , and also , could not be assigned to any of the seven identified major lineages within the Pucciniaceae. , instead of being maintained as a member of the Uropyxidaceae, was herein placed in Pucciniaceae, shown phylogenetically in close relationship to , both infecting the Berberidaceae. Additionally, our extensive phylogenetic analyses add guidance for future taxonomic revisions in the highly polyphyletic genus and other established taxa within the family Pucciniaceae.
（模式种）属由 Hennen 和 Ono 于 1978 年建立，以巴西塞拉多生物群命名。在巴西联邦区的普拉塔林塔采集的模式标本是第一个被报道在棕榈科（Arecaceae）上的锈菌。几十年来，作为一个独特属的地位一直存在疑问，从 1983 年第二版开始，代表了 Uropyxidaceae（榆叶梅科）的同义词。我们的分子系统发育分析以及形态学研究使我们能够拒绝这种同物异名，从而使 Pucciniaceae 内重新确立了 属。与形态相似的属，如新建立的具有两个种（和）感染天南星科宿主的 属，蕨类锈菌，以及 属，不能被分配到 Pucciniaceae 内的七个已确定的主要谱系之一。而不是被维持为榆叶梅科的成员，而是被放置在 Pucciniaceae 中，在系统发育上与感染小檗科的 属密切相关。此外，我们广泛的系统发育分析为高度多系的属和其他已建立的 Pucciniaceae 科内分类群的未来分类修订提供了指导。
