is the sole species of a monotypic genus, found in two distinct regions; southern Oregon and the Great Basin, and the central Rocky Mountains.
Leaves are long and narrow, often curved up at the edges, and grow radially outwards from the base, staying close to the ground. The lower ends of the leaves are enclosed by thin bracts. Leaves have conspicuous lengthwise veins.
Plants have no stems; the large, showy flowers also form from the base, and typically number between four and eight. Flowers are white, formed of a narrow tube between 2 and 3 inches long, and six narrow, oblong, equally-sized tepals, about one inch in length. Six stamens are attached at the top of the tube; they have white, thread-like filaments and bright yellow anthers.
