臺灣百合屬（百合科〉植物族羣之研究I──鐵砲百合變異型之組羣分析分

Populational Studies on Formosan Lilium (Liliaceae) I. A Cluster Analysis of Variants in L. longiflorum Thunb

鐵砲百合分布在本省北部及東北部沿海地區，及部份離島。因為它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羣，另在蘭嶼島亦選一個族羣，每一族羣採集二十至三十株樣品，分別在現場觀測十三項形態特徵。各族羣樣品的特徵數據先作基本統計，再以族羣為作業分類單位，根據各項特徵的平均值，計算出諸族羣間的高爾氏通用相似係數。根據上述係數矩陣，以未加權算術平均法進行組羣分析，並設定截羣線以顯示表型羣。各表型羣之間以何泰林－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。

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. longiflorum Thunb. was a variety whose name should be L. longiflorum Thunb. var. insulare Hort., Masamune (1954) thought that it was a new variety that is L. longiflorum 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) considered that there are two varieties in Taiwan that are L. longiflorum Thunb. var. scabrum Masam. and L. longiflorum Thunb. var. microphyllum Liu and Ying. Yang (1982) listed L. longiflorum Thunb. var. scabrum Masam. to this lily in Taiwan.
