Abstract

Drosera rotundifolia has one of the widest natural distributions of any carnivorous plant species, and is commonly associated with bogland habitats. New observations are presented of an ecologically unique population of D. rotundifolia growing on the gravely, poorly vegetated, slopes of an active volcano in Hokkaido, Japan. These field observations highlight the ecological plasticity of D. rotundifolia and indicate that under appropriate biotic and abiotic conditions, it can thrive in atypical habitats.

Keywords: Drosera rotundifolia, Mount Tarumae, Hokkaido, Japan
