Newbie sans collector here, pardon the cryptanthus. Not even sure if the white one is a sans, got it from the same store.

And this... Haworthia???

That first picture looks like Sansevieria cylindrica.

The cylindricas i googled seem to have a central point of origin, this one just shoots straight out of the ground randomly.

The white one on the right of the second picture really stumped me. Looks like a haworthia but stiff like a sansevieria.

Very light green in person, almost white. Leaves as stiff as my other sans, with the same brown leaf tips so I'm leaning toward some kind of albino sans maybe (is there such a thing?)?
