Taxonomic CommentsThe yellow lady's slippers are often considered to be three distinct species, Cypripedium calceolus being strictly Eurasian and the American plants being assigned to either C. parviflorum or C.pubescens (sometimes treated as varieties of C. calceolus). Kartesz (1999) treats the North American plants in this group as three varieties of broadly viewed species called Cypripedium parviflorum (vars. makasin, parviflorum, and pubescens); in 1994, he had treated them as two species, C. parviflorum and C. pubescens, not addressing "var. makasin" which only recently received new recognition. Another, questionably distinct entity, "planipetalum", has been variously treated as a species (e.g., by Kartesz, 1994), as a variety or subspecies of C. calceolus or C. parviflorum, or as a synonym of one of the more generally recognized taxa. Yet another entity, the species Cypripedium kentuckiense, was recognized about 1980 and is now generally accepted as distinct; these plants had previously been confused with one or more of the species in the parviflorum/pubescens group. As presented here, following the Kartesz (1999) treatment, Cypripedium parviflorum is viewed broadly, with varieties makasin, parviflorum, and pubescens. "Cypripedium parviflorum" of Kartesz (1994) corresponds to "C. parviflorum var. parviflorum" as presented here. LEM 28Feb01.
