Sap and mammilarias

[spikef35]

Can some give me some examples of mammilarias with sap (besides mystax) it seems from quick research most have clear Sap. Just a goofy question.

By "sap" you mean milky sap, I believe? If so, take a look here:

All species under the sub-genus Mammillaria, section Mammillaria should have milky sap.

As jfabio indicates Mammillaria was originally split into sections according to their sap:-

HYDROCHYLUS = watery sap

SUBHYDROCHYLUS = semi milky sap

MAMMILLARIA (syn. Galactochylus) = milky sap (in this case the generic name takes priority for the section as it includes the type species of Mammillaria)
