Goodyera pendula Maxim. (Orchidaceae), A Neglected Species in the Flora of Taiwan

台灣植物誌疏漏之蘭科植物-垂葉斑葉蘭

摘要


本文發表一種台灣植物誌未記載的蘭科植物:垂葉斑葉蘭(Goodyera pendula Maxim.),並提供植物圖、照片及分布圖以資辨識。垂葉斑葉蘭為台灣的稀有植物,目前台灣僅一份標本,採於台灣中央山脈北方的思源埡口附近森林內。垂葉斑葉蘭的植株高約12到14公分左右;花多數,全長在同一邊,成密穗狀花序,約4-6公分長;萼片約3到4公釐長,狹卵形;葉寬披針形到卵形,葉面沒有斑紋。這些特徵,明顯可與原生的另外19種同屬植物區別。

Goodyera pendula Maxim., a neglected species to the Flora of Taiwan, is described and illustrated here. Goodyera pendula Maxim. is rare and the specimen presently is known only from the mountain forest near Shih-yuan-ya-kou (at 1800-1900 m elevation), a spot in the northern part of the Central Mountain Range of Taiwan. It is distinguishable from the other 19 indigenous species in Taiwan by the stem 3-5 cm long; flowers many, one-sided, in dense spikes, spikes 4-6 cm long; sepals 3-4 mm long, narrowly ovate, sub-obtuse at apex; and leaves broadly lanceolate to ovate.
