Stenanthium occidentale A.Gray (syn. Anticlea occidentalis (A.Gray) Zomlefer & Judd) is native to the extreme northern California north to British Columbia. The flowers are tubular-campanulate with tepals greenish to brownish purple, 10–20 mm in length, and recurved distally. The plants stand 0.3-0.6 m (1-2 feet) tall. They can be found in various habitats but tend to inhabit areas where there is plenty of moisture. They flower in mid-summer. The photos below were taken by Kathleen Sayce on Angora Peak, Oregon, on north facing wet rocks.
