Family: Rubiaceae · Type: Subshrub · Native

Galium andrewsii subsp. andrewsii is a native California subshrub in the Rubiaceae family, recognized by Dense cushion, main stem obscure; awl-like keeled leaves longer than internodes, sharp.

Andrews' bedstraw is a California native perennial found in northern Coast Ranges, southern Sierra Nevada foothills, southern Coast Ranges, Transverse Ranges, and Peninsular Ranges in high chaparral and open woodland, often on serpentine or sandy-loam soils at elevations of 250 to 2,580 meters. Flowering from April to June, this plant produces small white flowers in delicate clusters. Growing as a low, dense, cushion-like plant with stems 5 to 15 centimeters tall, it forms compact mats close to the ground. Its leaves are awl-like, slightly keeled, and generally ascending, growing longer than the internodal spaces between stem segments. The plant's glabrous texture and tightly compact growth form make it well-adapted to its often harsh, exposed habitats.
