Abronia villosa var. villosa (Desert sand verbena) is a native California herb in the Nyctaginaceae family, recognized by wrinkled/pitted fruit and smaller flowers diagnostic within villosa group.
Desert sand verbena is a California native annual found in southern desert regions in sandy places within creosote-bush scrub at elevations below 1,000 meters. Flowering from February to July, this plant produces pink to magenta flowers in rounded clusters with perianth tubes 1.3 to 2 centimeters long and flower heads 6 to 12 millimeters wide. Growing with spreading stems that form low, sprawling mats across sandy ground, it creates delicate, web-like ground cover. Its small, oval leaves are arranged oppositely along the stems, providing a soft green backdrop to the vibrant flower clusters. The fruit features a prominently wrinkled body that appears distinctly pitted, adding textural interest to the plant's delicate structure.
