- 中文摘要： 本論文探討本省主要地生蘭29種的體細胞染色體數並就蝦脊蘭屬(Calanthe)罈花蘭屬(Acnthephippium）與鶴頂蘭屬(Phajus)三屬的唇瓣（Lip)形態，開花期分佈詳加研究 染色體數中16種為新知見，此等地生蘭染色體大多安定，數目相等者居多，然而種形成(Speciation)上開花期季節性的隔離機制(Seasonal isolation mechanism)與地理分佈上的隔離機制(Geographical isolation mechanism)在蝦脊蘭屬，鶴頂蘭屬的節(Section）分類階段上，?當極其重要的角色“
- 英文摘要： A total of 29 wild orchid species belonging to 7 genera are investigatedcytologically together with lip-morphology, flowering season and distribu-tion．Among the chromosome counts，16 species appears here for the firsttime．Terrestrial genera Calanthe, Phajus and Acanthephippium are thoroughly’studied．It is suggested that instead of rather stable chromosome numbers，there are very distinct seasonal and geographical isolations among the rankof sections in the speciation of Calanthe and Phajus．
