密鱗長花柄蘭之重新發現與新組合學名

An Observation on Yoania amagiensis Nakai & F. Maekawa var. squamipes (Fukuy.) Yeh et Leou (Orchidaceae), A Rediscovered Orchid from Southern Taiwan

在比較了長花柄蘭與天城山長花柄蘭之植物特徵之後，我們將密鱗長花柄蘭之學名組合成了Y. amagiensis Nakai & F. Maekawa var. squamipes（Fukuy.）Yeh et Leou。該變種與原種間的差別在於可完全伸展的花、花為粉紅色、側花瓣與唇瓣皆為全緣、唇瓣闊卵形。本研究提供其生育地環境、花期、查證標本等資料，並依據新鮮標本做詳細之型態描述、繪製圖示及台灣產長花柄蘭屬之種檢索表。 Considered of the characters of both taxa of Y. japonica and Y. amagiensis, we treated Y.japonica var. squamipes as Y. amagiensis var. squamipes. The latter can be distinguished from Y.amagiensis by spreading flower, pinkish flower, petals and lip entire and lip broad ovate. Morphologicalcharacters are described and illustrated after fresh material, also its habitat, flowering season, new key tothe Yoania species of Taiwan are provided.
