Mammillaria painteri forma monstrosa

Mammillaria painteri fa. monstrosa is a well known form in cultivation. I have had Mammillaria bocasana cv. caterpincy. I suspect that both are the same cultivars.

Aztekium hintonii monstrosa

This is a proliferous form of Aztekium hintonii. The Genus Aztekium consists of only two species A. ritteri and A. hintonii.

A hintonii was discovered only in 1991 together with another new species Geohintonia mexicana by George S. Hinton. Both species of Aztekium and Geohintonia grow on vertical gypsum hills in the State of Nuevo Leon, Mexico.

More variegates

There are many Astrophytum variegated hybrids, This is because all Astrophytum specioes hybridise with each other. The first picture shows a variegated cristate Astrophytum, grafted on Echinopsis species.

Variegation in Astrophytum myriostigma v. nudum , most probably of hybrid origin. Some variegates change colour with temperature and the reddish colour will turn back to yellow in spring and summer.

Variegation in Stenocactus is more rare.

The variegates

Coryphantha elephantidens is totally variegated and thus has to be grafted. It is not an easy plant to grow and does not like cold temperatures , otherwise it get marked easily.

Variegated Astrophytum asterias are getting more common among the cactus world. They produce offetes that can be grafted or rooted if they have some chlorophyll.

Echinopsis eyresii grows well on its own roots.
