Discussion

Cercis occidentalis ranges widely in California, but in Oregon it is found only in Jackson County.

Morphological trends of reduced leaf size and broader and shorter fruits were recognized in one population of Cercis occidentalis found in the Laguna Mountains east of San Diego (J. A. Ballenger 1992). This area warrants further collections and assessment of both flowering and fruiting specimens.
