Aconitum jaluense subsp. jaluense (Ranunculaceae) from Miyazaki Prefecture, Kyushu, Southern Japan

Abstract

Aconitum jaluense Kom. subsp. jaluense, one of endangered species in Japan, is first reported from the northern mountains of Miyazaki Pref., Kyushu, southern Japan. The Aconitum population was estimated to be composed of approximately more than 1000 individuals and is the largest at least in Japan. Although another aconite, A. japonicum Thunb. subsp. napiforme (H. Lév. & Vaniot) Kadota, was also found in the lower part of the mountain, no intermediates between the two aconites were recognized in the population.
