摘要

Stachytarpheta是马鞭草科最大的属之一,主要分布在巴西的campos rupestres中。本文描述了一新种lajedicola Stachytarpheta,并首次报道了该属在石灰岩露头中的出现。这种新物种是米纳斯吉拉斯州北部Caatinga地区的特有物种,生长在Matias Cardoso市的开放喀斯特地层中,当地称为lajed o。其主要的诊断特征是分枝纵缘发达,叶先端渐弱至尾状,花序有线状苞片,花序长度超过花萼。我们提供了详细的描述、插图、照片、地理分布图,并与形态相似的物种进行了比较。本文讨论了lajed o的生物学重要性和新物种的保护问题。

Stachytarpheta lajedicola (Verbenaceae), a new species from the Caatinga of Minas Gerais state, Brazil: the first report of the genus in limestone outcrops
Stachytarpheta is one of the largest genera of Verbenaceae, found mainly in the campos rupestres of Brazil. We describe a new species, Stachytarpheta lajedicola, and report for the first time the occurrence of the genus in limestone outcrops. The new species is endemic to the Caatinga domain, northern Minas Gerais state, growing in an open karst formation of the municipality of Matias Cardoso, locally known as Lajedão. Its main diagnostic characteristics are the branches with well-developed longitudinal edges, leaves with attenuate to caudate apex, and inflorescences with linear bracts, exceeding the calyx in length. We provide a detailed description, illustrations, photographs, a geographic occurrence map, and comparisons with the morphologically similar species. Stachytarpheta lajedicola may be considered Critically Endangered (CR), and the biological importance of Lajedão and the conservation of the new species are discussed.

期刊介绍: Experimental, theoretical and applied papers on all aspects of plant (including algae) and fungi biology are welcome. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. We expect that the submitted manuscript presents a great novelty in Botany, and this should attract a wide audience. Considering this, case studies are only considered if the narrative and implications are provided to be of general interest. Thus, manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology. Please see below some details for specific area.
