Physaria bellii (Bell's Twinpod)
Brassicaceae (Mustard)
The northern Front Range of Colorado is the only place in the world where Physaria belli grows. Look for it on shale outcrops. While its range is very limited, it is locally abundant. The seed pods of P. bellii are plump and constricted equally at both the top and bottom of the division. The common name "Twinpod" refers to the two chambered seed pod.
