C. fremontii Race Dry Creek (n = 6) Artificial Hybrid C. oppositifolia (n = 7)

Twelve individuals of this hybrid combination were produced.  Nine hybrids with C. fremontii Race Dry Creek as one parent had a mean pollen stainability of 5%.  Three hybrids with C. fremontii Race Elegans as one parent had a mean pollen stainability of 15%.  All hybrids exhibited good chromosome pairing and long multiple associations of chromosomes during meiosis.  Race Dry Creek is highly variable morphologically and the yellow-flowered form is shown only to illustrate the general habit of the race.  The white-flowered form was used to produce the hybrid illustrated here.
