Based on its octoploidy and the campanulate flowers, a hybrid origin between Subgen. Stylophyllum (possibly D. attenuata) and possibly subgenus Hasseanthus (probably D. virens ssp. hassei) or also a member of subgenus Dudleya is suggested in the protologue. The placement in subgenus Stylophyllum is merely for convenience.
