This is an agave, not an aloe. I'm not sure which one, though. Unless you have any other information to pin it down, I would like to propose to move this image to the generic agave listing.

I don't--thanks for the correction! How is it best moved?

Done!

At the bottom of the page for the image there's a link to "Move this image to another plant" and that's all it takes (plus approval by a moderator).

Thank you!
