Galium angustifolium subsp. borregoense

Borrego bedstraw, Borrego Bedstraw

Family: Rubiaceae · Type: perennial · Native

Conservation status: CNPS 1B.3

Borrego bedstraw is a rare (CNPS 1B.3) California native perennial found in southern desert regions including Palm, Hellhole canyons, Pinyon Mountain Valley, and San Diego County in granitic habitats among boulders on northern slopes at elevations of 350 to 1,250 meters. Flowering from April to June, this plant produces small white flowers in dense, many-flowered clusters. Growing with slender stems 35 to 60 centimeters tall, it has a woody base with stems featuring distinctive ridges wider than their grooves. Its leaves are very narrow, less than 8 millimeters long, and the plant remains completely glabrous except for hairy external flower corollas. The delicate structure and sparse growth make this bedstraw a subtle but characteristic component of its rocky desert habitat.
