Conservation status: CNPS 1B.3

Shaggy-haired alumroot is a rare (CNPS 1B.3) California native perennial found in the Santa Rosa Mountains in the Peninsular Ranges, inhabiting rocky areas at elevations of 2,200 to 3,500 meters. Flowering in July, this plant produces delicate white to cream flowers approximately 4 to 5 millimeters long with oblanceolate petals. Growing as a compact plant 8 to 25 millimeters tall, it forms dense, low-growing clusters with glandular stems. Its leaves are small and densely clustered, with a distinctively hairy texture that gives the plant its common name. The flower structure is subtly asymmetrical, with unequal calyx lobes and stamens nestled closely within the hypanthium.
