CALSIBE HYBRIDS (TETRAPLOID)
Hybrids with 4n=80 chromosomes,which can be derived from the same species  as diploid Calsibe hybrids, but have double the number of chromosomes and,  therefore, larger flowers. Such hybrids can either be produced directly  by colchicine treatment or as a result of crosses between  tetraploid parent plants. Such hybrids are fertile: in the process of  the reduction  of chromosome numbers during the production of sexual cells each chromosome,  due to the tetraploid structure, finds an analogue counterpart chromosome  of its own kind. - The flowers of Tetra-Calsibe hybrids of advanced generations belong to the most spectacular types of iris flowers.

Tetra-Calsibe hybrids can be back-crosses to tetraploid Chrysographes hybrids. We call the resulting 3/4 Chrysographes-1/4 Californicae hybrids Sibcal hybrids.
