E. dolomiticus is an exceptionally rare cycad (I know I say that a lot - they tend to be exceptionally rare) but is closely related to some of the more commonly grown species, E. eugene-maraisii, E. lehmannii and E. princeps.
This is a specimen at RBG Kew. I suspect in nature it'd be a bit more glaucous blue than this, quite a lot of the cycads in the Palm House aren't as blue as they should be. Dwarfed as it is by everything else, I also suspect this is quite a big one. It's supposedly quite a weak grower forming short multiheaded plants. I look forward to someday seeing another and finding out what they look like in other conditions.
