"Aristolochia yujungiana" (Aristolochiaceae): A New Species from Taiwan

台灣產馬兜鈴屬植物之一新種-裕榮馬兜鈴

摘要


本文描述台灣產的新種馬兜鈴屬植物-裕榮馬兜鈴。與台灣及鄰近地區的同屬植物做比較,此新種與台灣馬兜鈴、異葉馬兜鈴、大葉馬兜鈴與琉球馬兜鈴相似。但是,能以花萼筒的顏色與形狀與台灣馬兜鈴區分,以小苞片形狀與花萼筒檐部表面毛被差異與異葉馬兜鈴區別,以及用花萼筒檐部裂片形態與花萼筒形狀與大葉馬兜鈴及琉球馬兜鈴做區分。文中除形態描述及分類特徵摘要外,並提供線描圖、照片、保育等級以及與其近緣之各物種的檢索表與比較表,以助於物種鑒別之用。

"Aristolochia yujungiana" C.T. Lu & J.C. Wang, a new species from Taiwan is described and illustrated. Compared to its congeners in Taiwan and neighboring areas, "A. yujungiana" is similar to "A. shimadae", "A. heterophylla", "A. kaempferi" and "A. liukiuensis". However, it can be differentiated from "A. shimadae" by the perianth color and shape, from "A. heterophylla" by the bracteole shape and limb surface, and from "A. kaempferi" and "A. liukiuensis" by the limb-lobe morphology and perianthtube shape. A morphological description, diagnosis, line drawings, photographs, and conservation status of "A. yujungiana" as well as a key and a comparison table to morphologically similar species are provided to aid in identification.
