Name

Aleuritopteris × malacitensis (Rasbach & Reichst.) Windham & Schuettp., Taxon 74(2): 272 (2025).

• Basionym
  • Cheilanthes × malacitensis Rasbach & Reichst., Webbia 35(2): 269 (1982).
    • Typus: Spain, Prov. Malaga, Sierra Bermeja, serpentinite rocks under trees, E above road from Ronda to San Pedro de Alcantara, c. 23 km from Ronda at 1100 m, with C. guanchica. 16.X.1980, R.E. Holttum, H. Rasbach, T. Reichstein & A. Sleep RAS-167 (Holotypus: G, isotype: MA, both preserved after cultivation).
• Homotypic
  • Allosorus × malacitensis (Rasbach & Reichst.) Rumsey, Fern Gaz. 19(7): 277 (2014).
  • Oeosporangium × malacitense (Rasbach & Reichst.) Arana & Mor.-Saiz, Phytotaxa 433(3): 191 (2020).
  • Hemionitis × malacitensis (Rasbach & Reichst.) F.M.Vázquez, Folia Bot. Extremadur. 15: 149 (2021).

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.
