Trillium kamtschaticum Pallas ex Miyabe (1814).

Trillium camschatcense is a species of flowering plant in the family Melanthiaceae. It is found in the moist forests of East Asia, in Japan (Hokkaido and northern Honshu), Korea, China (Jilin Province), and eastern Russia (Kamchatka, Kuril Islands, Sakhalin, Primorye, and Khabarovsk).

Trillium camschatcense, a perennial herbaceous plant, is 30 to 50 cm (12 to 19.5 in) tall with white flowers. The plant grows in richly wooded areas, often on steep hillsides.
