A HUGE, robust wheatsheaf cluster of this rare species, found only once in this quality, some 30 years ago! This is an extremely rare specimen, of good aesthetic and important size for the species. Unlike most examples, it is actually blue, and not a boring ugly gray color! ex Sam Nasser thumbnail/toenail collection and Dave Stoudt Mexico collection. I bought it from Sam Nasser in 2004 and sold it to Stoudt in 2005, and now have what I consider the privilege to offer it again.
