Evolutionary developmental background of morphological adaptation of Heteropappus species(Asteraceae)

摘要为阐明海棘棘及其生态亚种的适应性叶片形态，以海棘棘沿海种为研究对象。分布在日本西部日本海沿岸的海鳞鱼和海鳞鱼。用形态学和解剖学方法对四国西部和九州东南部太平洋的岛类进行了研究。形态学分析结果表明，海丝桃叶片具有较强的生长活性。岛草的叶子比海蛾的大。hispidus。此外，解剖分析还表明，棘球蚴的表皮细胞与棘球蚴的表皮细胞结构相似。岛蝇的体型比海蝇小得多。hispidus。

To clarify adaptive leaf morphology of Heteropappus hispidus and its ecotypic subspecies, coastal species of H. hispidus ssp. hispidus distributed along seashore of Japan Sea in western Japan and H. hispidus ssp. insularis in Pacific ocean of western Shikoku and southeastern Kyushu were conducted using morphological and anatomical approaches. The morphological analyses revealed that the leaf of H. hispidus ssp. insularis has larger leaves than those of H. hispidus ssp. hispidus. Moreover, the anatomical analyses indicate that the epidermal cell of H. hispidus ssp. insularis is more decreased size than those of H. hispidus ssp. hispidus.
