It is endemic to Plumas County, California, where it is known from two occurrences in Lassen National Forest near Chester. There are approximately 250 individuals in existence.[1] It grows in scrubby, forested mountain habitat, only on glaciated andesite substrates.[2] This rare plant was discovered in 1997 and described to science as a new species in 2001.[2][3] This is a small, compact shrub growing in a mat up to 25 centimeters wide and 15 tall. The spreading stems bear woolly foliage, each leaf with an oval blade up to 2 centimeters long by 1 wide. The plant blooms with slender, erect flowering stems bearing umbels of flowers. The flowers are white, aging pink, hairy and glandular, and about half a centimeter long. The main threat to this species is logging.[2] Other threats include herbivory, competition with other plants, climate change, and changes in the fire regime of its native forest.[2] References1. ^Flora of North America 2. ^1 2 3 The Nature Conservancy 3. ^Corbin, B.
