Adobe popcornflower is a California native annual found in the Central Valley, eastern San Francisco Bay Area, southern Coast Ranges, and southern California coastal areas in vernal pools and moist clay soils at elevations below 700 meters. Flowering from March to May, this plant produces small white flowers with pale yellow appendages in delicate clusters. Growing with spreading to erect stems 10 to 40 centimeters tall, it has a somewhat taprooted structure with strigose (stiff-hairy) surfaces. Its cauline leaves are slender, measuring 2 to 6 centimeters long, with lower leaves more prominent. The fruit consists of small, ovate nutlets with distinctive irregular net-like cross-ribs and occasional slender, barb-tipped prickles along its surface.
