That T pseudopectinatus is very similar to mammillaria pectinifera, if it were not for the position of the flower buds being very different I would swear that it is almost the same cactus. I definitely need to get more turbinicarpus.
The Stenocactus looks very nice and healthy, it is always a pleasure to see your cacti so well cared for, mine sometimes get sick with so much rain but I like that they take on a look like they are in habitat.
Nice collection.
Thank you! You inspired me to find Obregonia and now I have 2 small ones 😄
Trust me, you inspired me first
