Navarretia hamata subsp. parviloba is a California native annual herb found in coastal areas including the Central Coast, San Francisco Bay Area, and southern Coastal Ranges in open, sandy habitats at elevations below 1,000 meters. Flowering from April to June, this plant produces delicate flowers with corolla lobes 2 to 3 millimeters long. Growing with distinctive linear to lanceolate leaves featuring unique hooked lobes that spread and curve, the plant has an intricate branching structure. Its leaves have an asymmetrical axis with equal spreading side lobes and a central recurved hook, giving the plant a distinctive architectural quality. The flower clusters emerge from axillary and terminal positions, with long-hairy bracts forming three-lobed tips that mirror the leaf structure.
