中文摘要 | 本文為台灣豆科植物花粉系列研究之一,藉由花粉形態特徵進一步探討台灣豆科植物屬及亞科間之關係。以台灣魚藤族(Millettieae)植物為主,利用掃瞄式及穿透式電子顯微鏡觀察野外現生的本族植物花粉形態及內部層次,共四屬十二種。根據觀察的結果,本族花粉的外壁層次一致,蓋基間層為圓柱狀,基層為連續至不連續狀,並具有分化的外壁紋飾。個別屬之類型差異則以花粉外壁紋飾及層次為依據,水黃皮屬(Pongamia)為單一類型、魚藤屬(Derris)可分為兩亞型、雞血藤屬(Millettia)及灰毛豆屬(Tephrosia)則各為三個亞型﹔經整合後,本族花粉形態則可分為四個花粉類型。由於屬間花粉之差異並不明顯,因此,除了水黃皮屬具有較明顯之特徵外,台灣魚藤族花粉特徵並不適合單獨利用為屬間分類之依據。 |
英文摘要 | The present paper is a part of a series of palynological studies for better understanding the relationship between the genera and subfamilies of the Fabaceae (Leguminosae) in Taiwan. There are 4 genera and 12 species found as native plants of the tribe Millettieae in Taiwan. The pollen grains of these 12 native taxa were studied, using scanning electron microscopy and transmission electron microscopy to examine and photomicrograph their pollen morphology. The pollen morphology of the tribe Millettieae in Taiwan is characterized by similar exine stratification, its columellate interstitium, the discontinuous foot layer, and the differentiated exine ornamentation. The pollen type for this study is based on the features of exine ornamentation and stratification. The genus Pongamia is represented by a single type, the genus Derris by two subtypes, and the genera Millettia and Tephrosia by three subtypes respectively but they can be grouped into 4 main types. Except for the genus Pongamia, the palynological characteristics alone are not sufficient for identification of the genera among the tribe Millettieae in Taiwan. |
