Illinois River Trail, Rogue River-Siskiyou National Forest, OR, 3/2018.

This is one of two similar ceanothus ground covers whose rugged foliage set it apart from the larger more common trailside shrubs in the buckthorn family, although they all share dense clustered flowerheads.  Of the two, Siskiyou Mat (pumilus) has 3 teeth at the holly-shaped leaf tips and grows in nutrient-poor serpentine soils unique to the Oregon-California border, as distinguished from Squawcarpet (prostratus) which has upto 9 teeth at the leaf tips and is more widespread throughout the west coast. The larger shrubby members of the family blossom with longer flower clusters, often showering us with petals in the spring; including Blueblossom (thyrsiflorus), just known as ceanothus, and Deerbrush (integerrimus), with typically white flowers.
