Data from: Aristolochia sinoburmanica (Aristolochiaceae), a new species from north Myanmar

Aristolochia sinoburmanica Y. H. Tan & B. Yang, a new species of Aristolochiaceae from Putao, Kachin State, Myanmar, is described and illustrated. According to morphology (strongly curved perianth, 3-lobed limb, as well as 3-lobed gynostemium, anthers 6, adnate in 3 pairs to the base of gynostemium, opposite to the lobes), the species belongs to Aristolochia subgenus Siphisia. It is morphologically similar to A. faviogonzalezii, A. hainanensis, A. tonkinensis, A. saccata, and A. xuanlienensis. The major differences between them are outlined and discussed. A detailed description, along with line drawings, photographs, habitat, distribution, conservation status as well as a comparison to morphologically similar species are also provided.

本文描述并图解了产自缅甸克钦邦葡萄县的马兜铃科（Aristolochiaceae）新种中缅马兜铃（Aristolochia sinoburmanica Y. H. Tan & B. Yang）。依据形态学特征——花被片（perianth）强烈弯曲，檐部（limb）3裂，合蕊柱（gynostemium）亦呈3裂状，雄蕊（anthers）共6枚，以3对的形式贴生（adnate）于合蕊柱基部，且与合蕊柱裂片对生——该新种隶属于马兜铃属（Aristolochia）Siphisia亚属。该种在形态上与费氏马兜铃（Aristolochia faviogonzalezii）、海南马兜铃（Aristolochia hainanensis）、东京马兜铃（Aristolochia tonkinensis）、囊状马兜铃（Aristolochia saccata）及宣涟马兜铃（Aristolochia xuanlienensis）近缘，本文概述并讨论了该新种与上述近缘种间的主要形态差异。此外，本文还提供了该新种的详细形态描述、线条绘图、实物照片、生境信息、分布范围、保护现状，以及与形态近缘物种的对比分析。
