中文摘要 | 本文以傳統分類法,數量分類法與變異體單親後裔檢定來探討臺灣野生鬼針屬(Bidens)植物分類問題,經由歸群分析結果可確B. bipinnata(鬼針)、B. biternata (鬼針舅)、B. pilosa(白花鬼針)及B. tripartite (狼把草)四分立種。同時白花鬼針的種群可以明顯的區分為4小群,舌狀花深裂的族群顯然與白花鬼針的其他種群有明顯之差異可區分,並經單親後裔檢定結果,證明為一穩定之性狀。作者因此將臺灣鬼針屬植物重新處理成四種,其中白花鬼針含四變種。新增之變種為B. pilosa var. trivalvis F. Y. Lu & S. L. Deng(裂瓣鬼針)。 |
英文摘要 | This study was carried out mainly to resolve the taxonomic difficulties of Taiwan Bidens plants based on the classical, numerical taxonomy and incomplete pedigree design. The data were analyzed by the clustering method. Four species, i.e. B. bipinnta. B. biternata, B. pilosa composition, and B. tripartite are clearly differentiated. The plants of B. pilosa were gouped into four infraspecific clusters, and the population with the unique character, triparted ligule is regonizable from the other varieties of B. pilosa and the result of progeny tesing porved the ligule triparted is a stagle character. In this study, we propose that there are four species of Bidens in Taiwan, among which B. pilosa is recognized by four varieties. B. pilosa var. trivalvis F. Y. Lu & S L. Deng is treated as a new variety. |
