Here is a picture I took of Agave hiemiflora just north of San Cristobal de las Casas in Chiapas - it does show a resemblance, for sure, though the rosette is a lot fuller on this plant. This population is the only time I have seen this - it isn't seen in the UK and I haven't seen it in a collection 'abroad' - so I have no idea as to whether this is representative of the type or not.
