Scrambling cryptantha is a California native annual herb found on the eastern slope of the Sierra Nevada Mountains, eastern Tehachapi, northern Transverse Ranges, southern Sierra Nevada eastern slopes, Mojave Desert, and northern Sonoran Desert in sandy soils, dunes, and slopes at elevations of 250 to 1,400 meters. Flowering from March to May, this plant produces small white flowers in delicate, sparse cymes. Growing with sprawling, prostrate to ascending stems 10 to 60 centimeters long, it has brittle branches covered in stiff, ascending hairs. Its linear to lanceolate leaves are 0.5 to 3 centimeters long, slightly succulent and rough-textured with sparse ascending hairs. The fruit consists of four distinctive nutlets, with one larger lance-ovate nutlet and three smaller lanceolate nutlets that are white-tubercled and dull.
