Notes: The FNA treatment by Magrath and Coleman (2002) notes the varietal taxonomy is controversial. They assign our material to var. nephrophylla. Their key separates the two proposed varieties on the basis of leaf shape, lip length, and flower color, while stating "the distinction is not sufficient to maintain the varieties." Magrath and Coleman (2002) also overlook the floral variation mentioned in H&C, yet another reason to combine the varieties, which we do here, following the treatment in JPM and other regional manuals.
