Aylostera Speg. (1923)

  • Aylostera deminuta (F.A.C.Weber) Backeb., Kaktus-ABC: 274. (1936) originally designated as Aylostera pseudominuscula (Speg.) Speg. in Anales Soc. Ci. Argent. 96: 75. (1923) syn. sec. Ritz & al. (2016)



The phylogenetic relationships in Aylostera were studied in detail by Ritz et al. (2016) based on the plastid DNA regions atpB-rbcL and trnS-trnG as well as AFLPs and morphological characters. Aylostera was confirmed as monophyletic and as distantly related to the clade that contains the type species of Rebutia K.Schum., thus justifying recognizing Aylostera as a separate genus. Based on their results, the authors suggested a new classification of Aylostera with nine species, this classification is followed here.
