摘要: | 本論文共整理台灣毛莨科鐵線蓮屬20個分類群,包括14種及6變種。其中增加1新記錄種:沖繩鐵線蓮(Clematis okinawensis);6新同物異名:C. alsomitrifolia, C. owatarii, C. pierotii, C. psilandra, C. sasakii, C. uncinata var. floribunda;更動3分類群的地位:亨利氏鐵線蓮(C. henryi)、小木通(C. lasiandra)、森氏鐵線蓮(C.henryi var. morii);接受小蓑衣藤(C.gouriana)與串鼻龍(C. taiwaniana)?不同種及更正鵝鑾鼻鐵線蓮(C.terniflora var. garanbiensis)之學名。
研究方法主依傳統分類及花粉形態處理。鐵線蓮屬在台灣之水準分佈可分?五型:(1)廣佈型,(2)山區型(海拔2,500公尺以下),(3)高山型(海拔2,500公尺以上),(4)海岸或石灰岩型,(5)恆春半島型。採用27個外部形態特徵,並以高爾(Gower)之法求出其間之相似係數,以梭克及密坎那(Sokal & Michener)法繪圖,而獲得相似係數75%時,可將台灣本屬植物區分?10群較?理想。 Revisions of 20 taxa (14 species and 6 varieties) of the genus Clematis are presented. During the course of the work, one new record (C. okinawensis), six new synonyms (C. alsomitrifolia, C. owatarii, C. pierotii, C. psilandra, C. sasakii, C. uncinata var. floribunda), and three new status (C. henryi, C. henryi var. morii and C. lasiandra) are proposed. The distinction between C. gouriana and C. taiwaniana is enough to recongnize them as different taxa. The C. terniflora var. garanbiensis was misidentified as C. terniflora var. robusta by Dr. Tamura. This study is based mainly on the morphological and palynological characters. The distribution of the genus in Taiwan is divided into five types: (1) widely distributed, (2) mountain type (below altitude 2500m.), (3) alpine type (above altitude 2500m.), (4) coast and limestone types, (5) Henchun peninsula type. The similarity coefficient of Gower and that of Sokal and Michener have been applied to analyze the 27 morphological characters of the 20 taxa. The ideal subdivision of ten groups is obtained when the similarity coefficient is at 75%. |
