Prostrate Verbena.
Verbena bracteata.
Vervain (Verbenaceae) family.

Annual or perennial herb 10 - 50 cm tall. Leaves: opposite, stalked, 1 - 6.5 cm long, pinnately cut, often three-lobed with lateral lobes smaller than the large central lobe.

The calyx is stiff-haired and 3 - 4 mm long, and the corolla is bluish to purple with the tube slightly longer than the calyx. Fruit: four linear nutlets, each 2 - 2.5 mm long, the calyx lobes surrounding the nutlets by coming together at the tip. Stems: several, decumbent to ascending, loosely branched, stiff-haired.
