臺灣野生茶(Camelliα sinensis f. formosensis) 乃泛指自生於臺灣中海拔山區的茶類植 物,臺灣植物誌將其中名稱為臺灣山茶。在分類史上,臺灣野生茶曾經被處理成數個不 同分類階層的歸屬。為了提供分類學者一個更客觀的看法,我們利用數值分類方法中的 群眾分析(c1uster analysis) 與非線性主成份分析(nonlinear principal component analysis) , 計算了165 份標本中的16 個營養及11 個花部特徵的測量值,並依據分析結呆來探究臺 灣野生茶與關條密切的茶(c. sinensis v訂• sinensis) 和阿薩姆茶(c. sinensis var. assamicα) 的區別。將營養及花部特徵獨立或合併進行群眾分析的結果幾乎一致地指出臺灣野生茶 在形態特徵上的獨立性。相反地,茶與阿薩姆茶的形態差異卻無法被解析出來。非線性 主成份分析則顯現休眠芽與子房的毛被狀態是區分臺灣野生茶以及茶與阿薩姆茶的最 有效特徵。參照目前分類學家對茶與阿薩姆茶這兩群植物的分類處理,我們建議臺灣野 生茶應該被處理成種的階層會比較恰當。
Camellia sinensis (L.) O. Kuntze forma formosensis Kitamura is generaJly referred to as the tea plant growing naturaJly in mid-elevation mountains of Taiwan. Several taxonomic treatments have been published for this plant in 也e past, but some contradictory results have been obtained. To assess the taxonomic position of the wild tea plant and explore its relationship with two other c10sely related taxa, C. sinensis var. sinensis and C. sinensis var. assami呵, 16 vegetative and 11 floral characters wer巴examined on 165 OTUs. The data were analyzed using cluster analysis and nonlinear principal components analysis. AJl c1uster phenograms consistently separated the native wild tea plant from two other related taxa. Conversely, pronounced admixture between C. sinensis var. sinensis and C. sinensis var. assamica was present. The nonlinear principal components analysis indicated that the surface features of buds and ovaries are two diagnostic characters. Based on the present study, it is proposed that the Taiwan native wild tea plant might deserve recognition as a distinct species.
