Lyall’s Mariposa Lily is also called Cats-ear, Lyall’s Star Tulip, or Lyall’s Butterfly Tulip.

Plant Description: Lyall’s Mariposa Lily is a 4 to 20 inches tall perennial herb with a single bract-like leaf about half way up and a 1 to 9 flowered umbel in the axis of 2 clasping, upper bracts. The single, grass-like basal leaf is flat and grows about as tall as the flowering stem.

Flower Description: The flowers are about 4 inches across, with tepals that are white or purplish tinged, with a purple crescent above the gland. The 3 petals are “cat-ear” shaped (i.e. have a long narrow base, widest at the center, with pointed tip) with a fringe of long hairs on the edge of the lower half and a few hairs on the lower surface.  The 3 sepals are about the same length, but narrower, more pointy and without a fringe.  There are 3 purple-green glands, transverse and arched upward, 6 stamens, and a short style with a 3-part stigma.

Ecology: Lyall’s Mariposa Lily is widely distributed on sagebrush prairies and on dry grassy hills and in open coniferous forests on eastern slope of the Cascades, at middle to high elevations.
