An Ariocarpus kotschoubeyanus f Rio Verde was also in flower yesterday.
I grafted a very young seedling onto pereskiopsis and degrafted 2 years later.
The plant has reached to a good size, 7 cm diameter.
It was a hot day today.
The maximum temperature reached to 39 'C in the afternoon.
Although the above mentioned situation, an Ariocarpus fissuratus f Big Bend was in flower.
I think it knows autumn will be very soon.
Although it is an out of flowering season for cacti, an Astrophytum myriostigma v nudum cv kikkou was in flower in the afternoon.
This species has the khoyo gene also but it is no longer to change the body color because the plant has reached to a mature age.
