台灣產饅頭果屬植物（大戟科）之分類研究

A Taxonomic Study of the Glochidion (Euphorbiaceae) of Taiwan

本研究以傳統分類及數據分類法，探討台灣產饅頭果屬植物之分類，確認本屬植物計9種，其中含1新確認種高士佛饅頭果（Glochidion kusukusense Hay.）。至於G. chademenosocarpumHay.及G. assamicum Hook. var. magnicapsulum Croiz. et Hara，兩種皆未能見標本，仍列為存疑種。以形態特徵經數據分類法所得之歸群圖與傳統分類法之結果大致相符。本文提供種類的檢索表、每種植物簡要特徵描述及手繪圖、學名考證與地理分佈及標本等資料。 A study on the Glochidion (Euphorbiaceae) of Taiwan was carried out with classicaltaxonomic method accompanied by the numerical taxonomy based on the morphological characters. Theresults of this study showed that the native plants of this genera in Taiwan can be demarcated into 9species, among which, G. kusukusense Hay. was newly reconfirmed. Owing to without availablespecimens, G. chademenosocarpum Hay. and G. assamicum Hook. var. magnicapsulum Croiz. et Harawere treated as insufficiently known species. The results drawn from numerical taxonomy was incompliance with those from the classical methods, and helpful to acquire the affinities among the taxa ofgenera and interspecies level. In this study, a short description with the drawings for each species as wallanalytical keys to the sections and species are given. Moreover, the treatment of scientific names hasbeenemphasized and the general distribution and citation of specimens of each species are also presented.
