Got these before my wife physically dragged me out of the venue to prevent me from buying any more ;)
Group pic above, and here are indiividual shots, filenames are the name of each plant:
The last two photos are both mammilarias - kinda neat how varied they can get within the same genus :)
I think those are the most interesting cacti I've ever seen.
Aww, thank you! There were many more interesting ones, but some way out of my price range (I am still trying to find some Aztekium specimens, but they're pretty rare in Japan and super expensive because of that)
