It is UVd, but the textures are procedural and those material networks are included. No texture maps obviously, though you could easily do your own since it is already UVd.
Also, this cactus is highly customizable because it is in separate pieces, each 'leaf' is simply grouped together with the others. With this cactus you can easily modify it to make it a much larger one by selecting one of the 'leaves' and duplicating it, scaling and placing it where you want it.
File formats besides .ma/.mb include geometry only.
