Crossosoma bigelovii is one of only a few species in the flowering plant family Crossosomataceae. It is known by the common name ragged rockflower and it is native to the Mojave and Sonoran Deserts of North America. It is a shrub growing one to two meters tall. It is intricately divided into thorn-tipped branches lined with clusters of small, deciduous, gray-green leaves no longer than about 1.5 centimeters. The flower cluster bears a single flower, which has white to purple-tinged petals about a centimeter long and narrowing to claws at their bases.
