Cactus / buiningii

 Although May is the last month in autumn in here, two uebelmannia species were in flowere yesterday afternoon.

The photo is one of them, U. buiningii.

I harvested seeds and sowed last summer but I could not see any germinations.

Cactus / retusus ?

 Several ariocarpus retusus related species were in flower yesterday afternoon.

The photo is one of them, 12 cm in diameter.

It seems the cactus is mixed other ariocarpus species but I am not sure because the cactus is propagated from seed given by my friend.

Cactus / scaphirostris

 Two degrafted ariocarpus scaphirostris were in flower yesterday.

The attached photo is on of them.

The cactus is quite small, is in a 8.5 cm square pot.

Cactus / retusus

 A degrafted matured ariocarpus retusus was in flower yesterday.

I bought seeds and sowed in 2003. A young seedling was grafted and degrafted later.

The cactus relies on own-roots currently.
