Abstract

Lilium longiflorum Thunb. is distributed in the northern and the northeastern seashore of Taiwan as well as in some of the outlying islands. The taxa below species level is not yet well-defined due to its highly morphological variations in different habitats. Wilson (1925) in his monograph “the lilies of eastern Asia “ stated that the Taiwanese L. lingiforum Thunb. was a variety shoes name should be L. logilorum Thunb. var. insulare Hort… Msamune (1954) thought that it was a new variety that is L. lingiforum Thunb. var. scabrum Masam. Hsei and Yang (1969) listed three name to cover this plant, which are L. longiflorum Thunb., L. longiflorum Thunb. var. insulare Hort., and L. longiflorum Thunb. var. scabrum Masam.. Liu and Ying (1978) Yang (1982) listed L. longiflorum Thunb. var. scabrum Masam . To this lily in Taiwan. Apparently, there are many different taxonomic views to this plant. The purpose of the present study, based on a collecting of a large amount of samples and analyzed morphological characters under fresh condition, is attempts to evaluate the infraspecific relationship at population level and to provide reference on horticulture research.

中文摘要

鐵孢百合分佈在本省北部及東北部沿海地區，及部分離島。因為他的外表型可塑性很大，以致它在種以下的分類地位尚未明確。本研究在本島選定十一個族群，另在蘭嶼島亦選一個族群，每一族群採集二十至三十株樣品，分別在現場觀測十三項型態特徵。各族群樣品的特徵數據先做基本統計，再以族群為作業分類單位，根據各項特徵的平均值，計算出族群間的高爾是通用相似係數。根據上述係數矩陣，以未加權算數平均法進行族群分析，並設定截群線以顯示表型群。各表型群之間以何泰林─T檢定法檢定差異顯著性，歸納出統計學上及生物學上均較合理的變異型。
