Der Artikel enthält eine ausführliche Beschreibung der neuen 

 aus der Sierra de Parras in Mexiko stammenden Art. Dieselbe 

 gehört zur Untergattung Eumamillaria, in die Sektion Galactochylus 

 und sehr wahrscheinlich zur Reihe der Tetragonae. Sie steht der 

 Mamillaria formosa Scheidw. sehr nahe, ohne jedoch mit ihr identisch 

 2U sein. Leeke (Halle a. S.).
