|discussion=<p><i>Draba bifurcata</i> is distinguished from other North American species by a combination of yellow flowers with styles (1–)2–3 mm and almost exclusively simple trichomes on the abaxial surface of cauline leaf blades. It is known only from Chiricahua, Santa Catalina, and White mountains in Apache, Cochise, and Pima counties.</p>
