Haworthias:
Haworthia attenuata
Haworthia cymbformi
Haworthia springbokvlakensi
Haworthia truncata (I love this one)
Haworthia viscosa
A Mammillaria plumosa
Melocactus intortus
An Optunia, all I could read of the tag was that the species starts with Teph It has interesting streamers.
Orthophytum saxicola
Sedum buxbaumanianum is what the tag read, I couldn't find it on the internet under this name.
A couple of the NOID's - they were ID'd but I didn't get a picture of the tag.
