| Grafted or not, still one of the most beautiful Mammillaria flowers. _________________ Chris admin

| I'll join in the display - you can just see the plant - on its roots, single headed. _________________ Chris43, moderator

| Great macro shots, Wolter. Those really are the most unusual spine clusters! And well, the flowers....... _________________ Chris43, moderator

| Sorry to say this, but in the second macro shot, it appears there are Red Spidermites on the tubercle! I know they are supposed to be susceptible to spidermite attacks too. Hey, does anyone know if they are self fertile or not? I just ordered a grafted plant and am expecting it by weeks end. |

| I doubt that the small reddish dots have anything to do with spider mites. The plants still look very healthy, no sign of spider mite damage. The tubercles are only 1.5 - 2 mm in diameter, which would make the small reddish dots about 0.05 mm, which I believe is much too small for spider mites. The macro shots of the areoles were taken with a Canon MP-E 65 mm lens, which can enlarge up to 5 times. Details like the spine-like structure of the areoles, which are not visible with the naked eye, will become visible with this lens. However, sharpness of depth is very, very small.
As far as I know, M. luethyi is not self-fertile, but perhaps there are exceptions. Two exceptions in my greenhouse: One plant of M. zephyrantoides is self-fertile, just like a M. saboae roczekii. The latter one was grafted on a piece of Opuntia. A roczekii on its own roots was not self-fertile. The Opuntia-grafted plant died a winter ago, but from the seeds I got some nice small seedlings (it looks as if roczekii germinates better than the others of the saboae group or M. luethyi).

| Very nice Wolter!
I agree with your marks on the germination of roczekii; in general I have good germination with seeds of this ssp.

| That's Great Wolter, It would really be bad to lose the plant. Very nice flowers too btw.
And I'll keep my fingers crossed I can find pollen for my plant if and when it blooms.
