Who can identify some of these cacti?

That's a good question.

Where did you get these pigs in a poke?

Too many nondescript seedling plants and plants without flowers to make even good guesses.

You will need a real plant identification psychic to come up with decent names for most of them.

Hi Cartman,

You might be able to find a psychic or two here.

the specimens not currently in flower or too immature to flower.

You will be able to get a few ID's on GardenWeb, though:

contribution would be that Opuntia 04 looks like ficus-indica, but I could be wrong.

Good luck!

Oh yeah!!!

Lame guesses from the peanut gallery on GardenWeb should be a barrel of laughs!!!!

If you were smart, you'd ask the experts in the Cacti etc mailing list instead.
