A Taxonomic Study of Angelica L. (Apiaceae) in Taiwan

[[abstract]]The genus Angelica Linneaus (Apiaceae) in Taiwan was taxonomically revised based on morphological, palynological, chromosomal and phytogeographical evidences. Morphology of vesture, bracteole shape, anther color and morphology of fruits are the important characters for the classification of Taiwan taxa. The texture of leaflet, leaflet vein and calyx-tooth also provide useful application for distinguishing some Taiwan taxa. Altitudinal and geographical distribution also shows more or less interspecific difference. As a result, seven taxa in Taiwan were recognized, including a new species A. aleensis and a new recorded species A. pubescens. Besides, A. morrisonicola var. nanhutashanensis, characterized by smaller leaflet and pubescent under surface of leaflet is treated as synonym of A. morrisonicola. Angelica taiwaniana which differed from A. morii only in leaflet morphology is also treated as synonym of the later.
