Xerophyllaceae Takhtajan. Beargrass Family.

A family of a single genus and 2 species, perennial herbs, of e. and nw. North America. Apparently sister to the Trilliaceae, but quite isolated genetically and based on that and the widely different morphology, best separated at family rank (see, Kim, Kim, & Kim 2019, who however do not promote this interpretation).
