Bryantiella

Bryantiella is a poorly known genus of two species, one of which is found in North America and one of which is found in South America.  The genus is ecologically remarkable in that it is adapted to the driest of desert conditions in the New World in the San Felipe and Atacama deserts (Porter and Johnson 2000).

The genus can be distinguished by its linear leaves, solitary inflorescence, and white pollen.

Biogeography

As with many Polemoniaceae, Bryantiella has a disjunct North America-South America distribution. It is found in both the Andes (B. glutinosa) and Baja California (B. palmeri)
