摘要

摘要我们描述并举例说明了迄今为止在巴西圣埃斯皮里托州发现的一个新种——叶下珠。该新种隶属于叶下珠属。Phyllantus和与其最接近的物种P.longitudicellatus的不同之处在于一系列特征，如茎上的分枝分布、每片叶的二级脉对数量、三级脉和叶缘的外观、柱头类型和花粉粒的表面。我们提供了新物种的分布图、非正式保护状况和酚学数据，这是巴西P.subsect物种的识别关键。并讨论了其在叶下珠剖面中的系统地位。

Phyllanthus capixaba (Phyllanthaceae), a New Species Endemic to Brazil Supported by Macromorphological and Palynological Evidence

Abstract We describe and illustrate Phyllanthus capixaba, a new species hitherto found in the state of Espírito Santo, Brazil. This new species is assigned to P. section Phyllanthus subsect. Phyllanthus and differs from their nearest species P. longipedicellatus by a set of characters such as aspect of branch distribution on the stem, number of pairs of secondary veins per leaf, appearance of tertiary veins and leaf margin, type of stigma, and surface aspect of pollen grains. We present distribution maps, informal conservation status, and phenological data for the new species, an identification key for the Brazilian species of P. subsect. Phyllanthus, and discuss its systematic position in the Phyllanthus section.
