Abstract

Abstract Doliocarpus is a neotropical genus with extensive representation in Brazil. During its taxonomic review, two new species from Brazilian Atlantic Forest were discovered and are herein described, illustrated, and compared to their close relatives. Doliocarpus heterophyllus can be recognized by its slightly undulate and subrevolute leaf margin along the lower third of the blade, with camptodromous venation, glabrous on the upper surface of the leaf, a cuspidate apex, and its glabrous fruit. Doliocarpus serrulatus has a serrulate leaf margin along the upper third of the blade, with craspedodromous venation, hirsute on the lower surface, and glabrous fruit. Diagnostic characters are discussed, accompanied by notes on their geographic distribution, informal conservation status, and photographs, and an emended key to all species of Doliocarpus of Atlantic Forest is also provided. Resumo Doliocarpus é um gênero neotropical com ampla representação no Brasil. Durante sua revisão taxonômica, duas novas espécies da Mata Atlântica brasileira são descritas, ilustradas e comparadas com suas espécies intimamente relacionadas. Doliocarpus heterophyllus pode ser reconhecida pela margem foliar levemente ondulada e sub-revoluta ao longo do terço inferior da lâmina, com venação camptódroma, glabra na face superior da folha, ápice cuspidado e fruto glabro. Doliocarpus serrulatus possui a margem foliar serrulada ao longo do terço superior da lâmina, com venaçãocraspedódroma, hirsuta na face inferior e fruto glabro. Caracteres diagnósticos são discutidos, acompanhados de notas sobre sua distribuição geográfica, estado de conservação informal e fotografias. Também é fornecida uma chave de identificação emendada para todas as espécies de Doliocarpus da Mata Atlântica.

标题巴西东部榄果属二新种及巴西大西洋林种检索表
Doliocarpus是一个在巴西有广泛代表性的新热带属。在分类学审查期间,发现了巴西大西洋森林的两个新物种,并在这里对其进行了描述、说明和比较。异叶Doliocarpus可以通过其沿着叶片下三分之一的轻微波状和亚旋变型的叶缘来识别,具钟状脉,叶上表面无毛,先端尖,果实无毛。细锯齿Doliocarpus serrulatus沿着叶片的上三分之一有细锯齿的叶缘,具锯齿状脉,下表面有多毛,果实无毛。讨论了诊断特征,并附上了关于其地理分布、非正式保护状况和照片的说明,还提供了大西洋森林所有Doliocarpus物种的修订密钥。Doliocarpus是一个在巴西有广泛代表性的新热带属。在分类学综述中,对巴西大西洋森林的两个新种进行了描述、说明,并与它们的近亲进行了比较。异叶Doliocarpus可以通过沿着叶片下三分之一的轻微起伏和亚旋转的叶缘来识别,具有钟状脉序,叶的上表面有釉,吐出的先端和无毛的果实。细纹Doliocarpus serrulatus沿着叶片的上三分之一具有细纹叶缘,具有craspedodroma脉,下表面有多毛,果实无毛。讨论了诊断特征,并附有关于其地理分布、非正式保护状况和照片的说明。还为大西洋森林的所有Doliocarpus物种提供了一个拼接的识别密钥。
