Abstract
Differentiation of flower colour is thought to be one of the most important factors promoting plant speciation. We describe the intraspecific variation of flower colour and its distribution in Limonium wrightii. We conducted a survey on 36 islands in the northwestern Pacific and discriminated six morphs of flower colour variation. Two flower colour morphs, pink and yellow, were most frequently observed, and their geographical distributions were basically allopatric. These two morphs were in contact in a narrow zone on Okinoerabu Island, located in the middle region of the Ryukyu Archipelago. In addition, orange, white, and ivory flower morphs were also found in this zone. The geographical distribution of pink and yellow morphs showed a "leapfrog" pattern; the distribution of pink flowers was divided into two areas, intercalated by the distribution of the yellow flower morph. The orange morph may have resulted from hybridization between the pink and yellow flower morphs.
