Trillium angustipetalum is a species of Trillium, plants which may be included within the lily family or the newer family Melanthiaceae. Its common name is narrowpetal wakerobin. It is native to northern and central California and southern Oregon, where it occurs in forests, woodlands, chaparral, and riparian zones. It is a rhizomatous perennial herb with one or more erect stems growing up to 70 centimetres (28 in) in height. There is a whorl of three large leaves generally described as bracts each measuring up to 25 centimetres (9.8 in) in length and round or somewhat oval in shape. They are green and mottled with brownish or darker green spots. Each stem produces one flower, which is held on top of the bracts. The ill-scented flower has three lance-shaped green or red sepals and three narrow purple or maroon petals measuring up to 11 centimetres (4.3 in) long.
