Abstract

During a floristic survey of Euphorbiaceae in cangas (areas of iron-rich soils) of the Serra dos Carajás (Pará State, Brazil), a new species of Euphorbiaceae was found. Croton carajasensis is only known from cangas vegetation and it is herein described and illustrated. The relationships of the new taxon with the most morphologically similar species (C. abaitensis, C. adamantinus, C. harleyi and C. ramosissimus) and its infrageneric position are discussed. We also include a distribution map, comments on habitat, flowering, fruiting, and a preliminary assessment of the species’ conservation status.

Croton carajasensis，巴西亚马逊帕拉州 Serra dos Carajás 的一个新物种

在对卡拉哈斯山（巴西帕拉州）cangas（富含铁的土壤地区）的大戟科植物进行植物学调查期间，发现了大戟科的一个新物种。Croton carajasensis 是仅见于坎加斯植被的植物，本文对其进行了描述和说明。本文讨论了该新分类群与形态上最相似的物种（C. abaitensis、C. adamantinus、C. harleyi 和 C. ramosissimus）的关系及其下属地位。我们还绘制了分布图，对栖息地、花期、果期进行了评论，并对该物种的保护状况进行了初步评估。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
