Deceiving gayophytum is a California native annual found in the Sierra Nevada, San Gabriel Mountains, San Bernardino Mountains, Modoc Plateau, White and Inyo Mountains, and Panamint Range in pinyon/juniper woodland and pine and fir forests at elevations of 1,800 to 4,200 meters. Flowering from May to September, this plant produces small white to pale pink flowers with delicate petals just over 1 millimeter long. Growing with slender branching stems less than 50 centimeters tall, it spreads with branches extending throughout the plant. Its leaves are generally 1 to 3 centimeters long and become increasingly reduced towards the stem's upper nodes. The fruit is slightly knobby, 6 to 8 millimeters long, and carries 10 to 25 seeds that range from glabrous to densely puberulent.

How to tell it apart

vs Epilobium: Gayophytum is a wiry, much-branched annual with tiny flowers and short straight capsules whose seeds lack plumes; Epilobium has long linear capsules that split to release seeds tufted with hairs (coma).; vs Camissonia: Gayophytum has a very short or absent floral tube, so the petals appear to sit right on the ovary; the Camissonia group has a distinct floral tube above the ovary and generally yellow flowers.; vs Oenothera: Gayophytum is a slender diffuse annual with minute (1-2 mm) flowers; Oenothera (evening primrose) has large showy flowers on a long floral tube.; vs Clarkia: Gayophytum flowers are tiny with plain entire petals; Clarkia has larger, often lobed or clawed petals and 4-grooved capsules.; vs Eremothera: Gayophytum has a threadlike branching habit with short capsules held along the stem; Eremothera and Chylismia have basal rosette leaves and longer tubular-based flowers.
