There is some confusion about this species. Several quite different cultivars have been described under this name, including some on the GRW (see here and here). Mr. Feuillet and John Boggan of the Smithsonian Institution believe that this is likely the true species. Photos (here and here) of a plant in the Smithsonian collection, identified as the true species, are very similar to this specimen and possibly clones -- the differences may be cultural in origin.
