Discussion

Fallugia paradoxa grows in diverse habitats, ranging from the Chihuahuan, Great Basin, and Mojave Desert scrub to woodlands. Throughout its range, plants exhibit considerable variation in underground structures, and lobing and indument of leaves, bracts, and epicalyx. In sandy drainages, it is commonly rhizomatous and colonial, especially in California. In upland sites, it is not rhizomatous. Lobing of sepal tips and epicalyx bracts shows considerable variation on individuals and to some extent regionally. Lobes are more consistently found in plants from Texas and northern Mexico.
