Trees, Shrubs and Conifers: Cupressus ID question, 1 by plantmover

Can anyone confirm if Arizona Cypress 'Carolina Sapphire' is the same tree as Cupressus glabra? In the plant files there is quite a difference in the height and spacing of the two types, not to mention the nomenclature confusion. I got a tree on the clearance rack, thinking it was Carolina Sapphire and would grow to 10-12'....now I'm not so sure.

Cupressus glabra 'Carolina Sapphire' http://davesgarden.com/guides/pf/go/79395/
Cupressus arizonica, aka Cupressus glabra http://davesgarden.com/guides/pf/go/54341/

For all I know, it may even be a Cupressus glabra 'Blue Ice' http://davesgarden.com/guides/pf/go/79394/

HELP please!
