Calycadenia fremontii x C. pauciflora
|C. fremontii Race Ciliosa (n = 6)||Natural Hybrid||C. pauciflora Race Ramulosa (n = 6)|
Crosses between these species produced 124 individuals with a mean pollen stainability of 9%. Parental forms producing hybrids included Races Ciliosa, Dry Creek, Elegans, and Healdsburg of C. fremontii (all n = 6), and Races Pauciflora (n = 5), Ramulosa (n = 6), Tehama (n = 6), and Wurlitzer (n = 6) of C. pauciflora. Chromosome pairing in the hybrids during meiosis was high and multiple associations were formed that indicate the species differ by a minimum of 2-4 reciprocal chromosome translocations, depending on the races being compared.
