摘要

本研究從2011年到2014年，於石蒜開花期及出葉期前往馬祖東引進行調查，依形態特徵比對文獻後將東引原生石蒜區分成紅花石蒜、玫瑰石蒜、紅藍石蒜及換錦花等4類群。紅花石蒜花色紅，花被片反捲皺縮，花被筒長0.8公分，雄蕊伸出花被片外，葉片可區分成長葉型、短葉型及一般型三型。玫瑰石蒜花色玫瑰紅，花被片反捲皺縮，末端帶藍紫色雜斑，花被筒長0.8公分，雄蕊伸出花被片外，數量少。紅藍石蒜花色玫瑰紅，花被片末端帶藍紫色雜斑，筒狀花形略為開張，花被片輕度反捲無皺縮，花被筒長1.04公分，雄蕊與花被片等長，略微伸出。換錦花分布最廣、數量最多，花色粉紅，花被片末端帶藍色雜斑，筒狀花形，花被片無反捲平整，花被筒長1.6公分，雄蕊與花被片等長，並發現白花變異株。

Field surveys of ＂Lycoris＂ during flower and leaf sprouting season were executed between 2011 and 2014 in Dongyin Matsu. ＂Lycoris＂ native to The Dongyin were classified into 4 species according to morphological characteristics and literature review, including ＂Lycoris radiata＂, ＂Lycoris＂ × ＂rosea＂, ＂Lycoris＂ × ＂haywardii＂ and ＂Lycoris sprengeri＂. ＂Lycoris radiata＂ is red flower with reflexed tepals, a perianth tube 0.8 cm in length, and protruding stamens. Lycoris × rosea, a rare species, is rose red flower with mottled blue and purple reflexed tepals, a perianth tube 0.8 cm in length, and protruding stamens. ＂Lycoris＂ × ＂haywardii＂ has rose red flower, and blue on the tip of tepals that are slightly opened, reflexed, and tubular. This species has a perianth tube 1.04 cm in length, slightly protruding stamens, and tepals equal in length. ＂Lycoris sprengeri＂, widely distributed on Dongyin, is pink with mottled blue, tubular, flower-shaped tepals without an anti-roll fold, a perianth tube 1.6 cm in length, and stamens and tepals equal in length.
