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.本文记述并图解了产自缅甸克钦邦葡萄镇的马兜铃科（Aristolochiaceae）新种滇缅马兜铃（Aristolochia sinoburmanica Y. H. Tan & B. Yang）。依据形态特征（花被强烈弯曲，檐部3裂，合蕊柱3裂；花药共6枚，以3对的形式贴生于合蕊柱基部，与合蕊柱裂片对生），该种隶属于马兜铃属（Aristolochia）Siphisia亚属。该种与A. faviogonzalezii、A. hainanensis、A. tonkinensis、A. saccata及A. xuanlienensis形态相近，本文概述并讨论了它们之间的主要差异。此外，本文还提供了该种的详细形态描述、线条图、照片、生境资料、分布信息、保护现状，以及与形态近缘物种的对比分析。
