Chaerophyllum colensoi, or mountain myrrh, [2] is a species of flowering plant, endemic to New Zealand. [3] It is found on mainland New Zealand and the Chatham Islands. It is a perennial. [3] It is found in alpine environments on the North Island, and throughout the South Island. It either grows near ephemeral water sources or on the edges of tarns. [4] Weeds and changes in hydrology due to differing land usage are its major existential threats. [4] The type specimen was sourced from "New Zealand", and was collected by William Colenso. [5]
