At last .... flowers

Terry,

Do the Lithops windows flouresce? Or their body pigmentation?

Andrew
Good question.
I will endeavour to answer it when I get a moment. I have a busy schedule today but I'll do my best to try the light source, even if I cannot get around to getting any images.

No fluorescence from the bodies. But the dead flower parts from last year do fluoresce.

There is a beguinii var senilis. Same as T. mandragora?

Turbinicarpus mandragora is quite a different beast....... rarely seen in cultivation, very difficult to grow successfully, with a large swollen napiform or tuberous root system. It occurs in habitat in one deep valley or canyon in the Mexican state of Coahuila, which is rarely visited because of its remoteness and the extremely difficult tracks into and again out of the valley.
I seem to recall that old name of T. beguinii var. senilis was simply a form with distinctly longer white central spines.

Thanks Ralph.
That is a very different plant
