*Pyracantha sp.
EVERGREEN SHRUB.  A single very large, old, spreading shrub was found under ash trees in a wash among granite tors.  Commonly cultivated in southern Arizona, but from its location, this one grew wild.  Included in this list for its enormous size and wildlife value (many birds eat the berries, and the branches provide year-round shade and cover).  The extremely long, arching branches are more flexible and less thorny than is commonly seen in the heavily-pruned bushes in cultivation.
FAMILY:  Rosaceae (Rose Family)
