Umbelliferae in Japan I

Abstract

The Umbelliferae in Japan has been classified into 30 genera and 90 species. Taxonomy of these species has been treated by several authors. However, the scientific names of some taxa are different by the authors, so I attempt to sort out the right scientific names of these species and genera in this paper. The genus Spuriopimpinella Kitag. is united to the genus Pimpinella L., and the genera Tilingia Regel and Dystaenia Kitag. to the genus Ligusticum L. It is clear that Angelica sect. Acutilobi with 7 species is an endemic section of the Japanese Islands. In this paper a key to Japanese genera is provided and 11 genera are treated; Hydrocotyle, Centella, Sanicula, Torilis, Anthriscus, Osmorhiza, Pleurospermum, Bupleurum, Cryptotaenia, Pternopetalum and Aegopodium.
