Desert winged rockcress is a native annual herb found in northern and eastern Mojave Desert regions, inhabiting washes, steep hillsides, dry flats, scree, calcareous rubble, rocky bluffs, and exposed crevices at elevations of 50 to 1,400 meters. Flowering from March to April, this delicate plant produces small white flowers with distinctive petals emerging on slender stems. Growing with branched stems 10 to 35 centimeters tall, it develops intricate, deeply divided cauline leaves with linear to lance-linear lobes 2 to 20 millimeters long. Its leaves feature minute, forked or many-branched hairs, creating a fine, intricate texture across the plant's slender structure. The small white flowers develop into spreading or reflexed fruits with tiny oblong seeds approximately 1 to 1.4 millimeters long.
