Cactus / clavata

 A neoporteria  clavata was in flower in this afternoon.

I could see some flowering buds in mid of June but it was hard to open because it was in winter.

I had quite many neoporteria species but only this one has remained.

Cactus / kotshoubeyanus

 An ariocarpus kotschoubeyanus f Rio Verde was in flower in this afternoon.

It was mid of winter and so I thought the cactus could not open a flower but it could.

The cactus is a degrafted one, 10 cm in diameter.
