Notes

Hybrid formula was "Cheilanthes guanchica Bolle × Cheilanthes pteridioides (Reich.) C.Chr." in original, but "Cheilanthes pteridioides" was used for the tetraploid Oeosporangium acrosticum, and "Cheilanthes maderensis" was used for the diploid Oeosporangium pteridioides by Rasbach & Reichstein 1982 and other contemporary publications. For Cheilanthes × tolocensis the different parentage "Cheilanthes guanchica Bolle × Cheilanthes maderensis (Reich.) C.Chr." was given by Rasbach, Reichstein & Schneller 1983 as hybrid formula, together with a different genotype.
