本文報導台灣東部發現之紅泡刺藤（Rubus niveus Thunb.，薔薇科）野生族群。R. niveus雖曾被台灣植物誌採用，但於2009年最新的分類訂正認為台灣無此物種，因以往此種之紀錄實際均屬白絨懸鉤子（R. incanus Sasaki ex T. S. Liu & Yang.）。也因此，我們的發現重新確認了紅泡刺藤在台灣的分布。紅泡刺藤可依以下特徵與台灣產本屬其他物種區別：具7-9枚小葉之羽狀複葉；小葉葉背密生白色絨毛；繖形狀繖房花序；花瓣直立，紫紅色；及花萼不具皮刺。
The wild population of Rubus niveus Thunb. (Rosaceae) is recently reported from eastern Taiwan. Although the name “R. niveus” had once been adopted for the Flora of Taiwan, it was excluded in the latest taxonomic revision in 2009 as previous records were in fact corresponded to R. incanus Sasaki ex T. S. Liu & Yang Our discovery, therefore, reconfirms the occurrence of R. niveus in Taiwan. R. niveus could be distinguished from other congeners in having compound leaves with 7-9 leaflets, leaflets abaxially densely whitish tomentose, umbellate corymbs, pink flowers with erect petals, and unprickled calyx. |
