- 中文摘要:
有關茵芋屬植物的分類文獻頗多,但彼此意見紛紜。本研究以各種解剖學方法探討該屬花部
數目、性別與葉部等各項構造。發現花部特徵在個體間變異較大,但呈連續狀態。葉外形及大小
也有相同現象,但內部構造有較穩定而共通的特徵。綜合這些結果及地理學方面該屬分佈的途
徑與花果期的資料顯示,整個臺灣的族?並未受到各種隔離機制的影響而造成不連續性 (discon-
tinuity),是故推論目前臺灣茵芋屬植物不宜分為三個種?;可能是原本已隔離的日本茵芋 (S.
japonica)和深紅茵芋 (S. reeversiana) 重新在臺灣組合而成的一個複合?。
m - 英文摘要: There are various kinds of opinion con-cerned with the classification of Skimmia whichis a small genus of Rutacean plants in Taiwan.Studies on morphology, anatomy, flowering timeand geographical distributions were conductedwith specimen from Taiwan and Japan. A com-parative analysis using 59 specimens and thecharacteristics related to floral parts and leavesindicated that variations found in Taiwan popula-tion of Skimmia were without any conspicuosediscontinuity. Results of these studies and flow-ering time and geographical distributions revealthat S. arisanensis and S. distincte-venulosa aremorphologically indistinct from one another,and this complex groups may be evolved by thereunit of S. japonica and .S. reeversiana twooriginally isolated species.
