Mammillaria jaliscana TL 721

A closer look at the spination of M. jaliscana TL 721 from Guadalajara, Jalisco:

Very nice - and such short spines! - makes a great photo.

I received some comments from T. Linzen about M. jaliscana:
"Wer kennt eigentlich die echten M. jaliscana, so wie sie beschrieben wurde, mit kleinen purpurrosa Blüten? So wie ich sie in der LBS vorgestellt hatte. "
"Who knows the real M. jaliscana, like described the original description, with small purplish-red flowers? like I presented in the Loose Leaf Collection."

In this Loose Leaf Collection T. Linzen states that the ones, seen as M. jaliscana nowadays, have nothing in common with the original description.
The ones we know as M. jaliscana have flowers which are 2 cm in diameter, and are twice the size like said in the original description. The habitat locations are also not comparable with the type location. It's thanks to Reppenhagen and Lau that we have now plants in our collections which can not be associated with the real M. jaliscana.
It seems that Lau and Reppenhagen have named all their discoveries from the stylothelae, with firm spination, jaliscana.
The real M. jaliscana is with the small (1 cm), purplish-red flowers, the whitish fruit and 6 (-12), centrals spines, distinct characterized.
The ones that we know as jaliscana belong more to mercadensis and zacatecasensis.

I think, that the type of M. jaliscana with the dark red colored small flowers is well known. Not maybe finally through the Color-Plate photo from Pilbeam/Weightmann.
Fact is however that plants are not frequently found in the collections. There are today many forms, for which are called M. jaliscana, that one can also distinguish partly clearly, that however, as self-sterile plants, itself well among each other has dusted. One of this form has been described as M. kleiniorum.
