Found at elevations above 1,000 feet, spectaclepod is one of the
long-flowering species blooming from February to October. The large
flower heads are pleasantly fragrant, and the peculiar, flat, double
fruits resemble tiny spectacles protruding at right angles to the stem.
This species is found in the Petrified Forest area of northern Arizona,
and Hopi Indians are reported to use the plant in treating wounds.
Another species, California spectaclepod, is often abundant, covering
sandy flats of the lower deserts. This species blooms from February
through April and sometimes again in the fall.
