While working on the cytogenetics of a range of alooids (Asphodelaceae subfam. Alooideae) in Lisbon, Portugal, Flávio Resende described several new formae in species of rambling aloe, a group that at the time was interpreted as section Macrifoliae Haw. in Aloe L. This group is nowadays accorded genus rank, as Aloiampelos Klopper & Gideon F.Sm. One of the formae described by Resende, Aloe ciliaris Haw. f. gigas Resende, a pentaploid, is a hybrid between the hexaploid Aloiampelos ciliaris (Haw.) Klopper & Gideon F.Sm. var. ciliaris and the tetraploid A. ciliaris var. redacta (S.Carter) Klopper & Gideon F.Sm. Aloe ciliaris f. gigas is here raised to the rank of nothovariety, as Aloiampelos ciliaris nothovar. gigas (Resende) Gideon F.Sm. & Figueiredo. We neotypify the replaced synonym, Aloe ciliaris f. gigas.
