M. glochidiata has been grown from seed of plants, which I had grown from seed of plants collected by Fitz Maurice in the Barranca de Tolimán. According to Fitz Maurice this should be the real M. glochidiata (he published about it in the JMS several years ago). Plants in nature are white or pink flowered.

Mammillaria glochidiata v. xiloensis
This variety is differentiated by Reppenhagen for its thick roots, larger, more flat-globular stem, and greater number of spines, both radial and central (of a yellow cast).
As Hunt indicates, it bears little relationship to M.glochidiata.
it is more like the type of M.crinita occurring in the same area.
