Cactus / ambatoense

 Two gymnocalycium ambatoense were in flower in this afternoon.

The photo is one of them.

I bought small plants in 2003.

Cactus / mexicana

 A degrafted / rooted Geohintonia mexicana was in flower yesterday afternoon.

The cactus was grafted once but it was degrafted and rooted. The rooting of this species is not difficult.

The cactus is 7 cm in diameter.

Cactuc / luethyi

 A  grafted Mammilaria luethyi was in flower yesterday.

I kept many of this species about 10 years ago but I lost all of them.

This one was returned by my friend last year.

Cactus / coahuilense

 A matured Astrophytum coahuilence was in flower in this afternoon.

I bought a small plant in 2003.

The cactus is 23 cm tall and 16 cm in diameter.

Cactus / hintonii

 A rooted off-set of Aztekium hintonii was in flower in this afternoon.

The cactus is 8 cm in diameter.

The rooting of hintonii is not difficult but you have to select an off-set which is more than 3 cm in diameter.

Cactus / aselliformis

 A pelecyphora aselliformis was in flower yesterday.

As you can see, the flower is not normal, which petals are very thin.

This degrafted one is 7 cm in diameter.

Cactus / ritteri

 A degrafted aztekium ritteri was in flower in this afternoon.

A short pereskiopsis stock is still attached and the cactus relies on the stock.

The cactus is very small. Overall size is 8cm in diameter.
