This plant looks more like Agave parryi var. truncata than regular Agave parryi.

Well I retract the above comment.... After looking at the A. parryi subsp. parryi database entry, I went back and looked at pictures of both plants and changed my mind... this plant is A. parryi subsp. parryi and should be moved to that plant's database entry as it would be one of the first actual A. parryi subsp. parryi pictures with that entry. Most of the actual A. parryi pictures in there are actually A. parryi. var. truncata. Some of the A. parryi subsp. parryi plants look a lot like A. parryi var. truncata, but they have slightly more teeth and get slightly more elongated leaves with time...

Sorry for the confusion...
