Cactus seedlings

20 years ago

I know cactus seedlings are nearly impossible to ID, but I bought package of mixed seeds, about half of them have sprouted, and seem to be doing well. I'd like to try to figure out which are which, but all I have is this list:

Coreus gigantea/Saguaro

Cylindropuntia spinosior/Cane Cholla

Ferocactus cylindraceus(acanthodes)/Compass Barrel

Ferocactus wislizennii/Fishook Barrel

Lemairocereus thurberi/Organ Pipe Cactus

Lophocereus schottii/Senita

Opuntia chlorotica/Dollar Prickly Pear

Opuntia engelmannii/Dessert Prickly Pear

Opuntia oreocola/Coastal Prickly Pear

Opuntia phaeacantha/Small Prickly Pear

Pachycereus pringlei/Cardon

Which are the species that are supposedly in the mix...

Does anyone know of any websites/books which might show some pictures of cactus seeds/seedlings so I can start trying to figure them out?

All the Opuntia will look like this when they first germinate, then they will rapidly develop their first pad.

Saguaro and the other columnars look very similar at first, the two seed leaves tend to be shorter and very pointed.

The Ferocactus will be more like little balls which quickly develop a tuft of spines on top.

In all cases, it will be difficult to determine the exact species for at least a year.

How are yours doing? Do you have any pictures of the seedlings or several months after sprouting? Have you had any luck with ID? I also recently purchased a cactus seed mixture and am in the same predicament. Please share if you have anything.
