The spikey ones are a Trichocereus sp. very nice. The weird looking one is a Leuchtenbergia principis, lovely. The large flowering one kinda looks like a Cereus sp. but would need a pic of the stem for better ID. There is one with a flower which I can't tell because it's just a flower and that Penis Cactus is very cool. Nice collection you have there Gracie. Would love to see some more pics.
A side note, if you mark your pics as private you are not able to post them here on the forum. Stay tuned people, new gallery coming soon.
