|discussion=<p><i>Pleradenophora bilocularis</i> reaches its northern limit of distribution in southwestern Arizona and is widespread in adjacent Sonora, Mexico. Across its range, there is a six-fold variation in leaf width with collections from Baja California being much wider (to 3 cm) and formerly recognized as a distinct variety (V. W. Steinmann and R. S. Felger 1997). The species is a minor source for “Mexican jumping beans” from seeds parasitized by moth larvae. Indigenous populations used the latex as arrow and fish poison (C. E. Bradley 1956).</p>
