Flowers: Yellowish-white and fragrant, rotate or shallowly cup-shaped with 5 lanceolate lobes, corollas 1.5-3 mm wide, calyx 0-5 lobed, stamens 3-5 or appearing 1-3 from fusion, anthers often larger than the filaments and twisted together, styles 1-3, stigmas large and lobed, ovaries inferior with 3-5 chambers, placentas parietal and growing into chambers, infloresences with staminate flowers in small axillary clusters and pistillate flowers solitary with 1 per node.

Notes: This vine with its pretty white flowers can get quite large with thick masses of stems, sometimes entirely covering the plants its growing on. Look for this species in Arizona along washes in Maricopa, Yuma, Pinal, and Pima counties. Ethnobotany: Unknown. Etymology: Brandegea is named for Townsend Stith Brandegee (1843-1925), a pioneer western botanist who collected throughout California, Baja and western Nevada, and bigelovii is named for Dr. John Milton Bigelow (1804-1878), a professor of botany at Detroit Medical College, who collected in the West under Whipple in the Pacific Railroad Survey of 1853-1854.
