420:. This distribution only covers an area of around several hundred acres. The population boundaries exhibits some annual fluctuations, but otherwise it has remained in the same suitable habitat area for some time. The rugged terrain makes tracking populations difficult, along with the summer deciduous habit.

This species is threatened by land development and recreational activity. A significant portion of the land that this species occurs on is designated as "open space" by the Conejo Open Space
Conservation Agency, or on parklands managed by Ventura County. The remaining habitat is either owned by local

Arising from stems may be multiple rosettes, at most several, each 1 to 6 cm wide. The roots are narrowed and swollen at irregular intervals, with rhizome-like branches extending from the roots of the plant. The rhizomes often resemble shriveled roots for most of the year, and are very fragile.
366:
The stems are 2 to 7 mm wide. The leaves are deciduous in summer, and are 1.5 to 4 cm long, 3 to 6 mm wide, and shaped oblanceolate, glaucous in youth, but papery when dry. The base of the leaves is a wounding purple to red. The peduncle of the inflorescence is 4 to 23 cm tall,
363:
The rhizomes are not a good character for field identification. Because the plant is rhizomatous, the above-ground parts of the plant may die back for several years, surviving underground as a rootstock. It is a long-lived species, with some examples surviving over 24 years in cultivation.

The entire species is located over a 16 km stretch of land on an east-west ridgeline of Conejo volcanics, on the western end of the Simi Hills, along
Mountclef Ridge, and terminating near
