Aylostera pelzliana (Rausch) Mosti & Papini

Regarded by some as a form of Aylostera eos, A. haagei or A. pygmaea. A lot of confusion exists in nurseries and growers between A. pelzliana and other pink / whitish flowered larger Mediolobivias. Described as “muted red” in colour rather than pink, and with thinner spines than A. eos.

The description is here.
