Mammillaria fuscohamata

Mammillaria fuscohamata
The invalid name has been picked up by Reppenhagen, referring to plants he has collected in Jalisco, at Cuarenta (Backeberg did not cite a specific locality, other than Jalisco).
Plants have been commercially circulated in the last ten years or more, under the field collection number REP 638, but the name remains invalid.
Hunt refers it to M.jaliscana, the Fitz Maurices (pers. comm.) to M.mercadensis, in which they embrace M.jaliscana
