Cypripedium parviflorum, commonly known as yellow lady's slipper[2] or moccasin flower,[3] is a lady's slipper orchid native to North America.[1] It is widespread, ranging from Alaska south to Arizona and Georgia.[4]
Taxonomy[]
C. parviflorum is a highly variable species, which is a result of both hybridization and phenotypic plasticity.[5]
Four varieties are widely recognized. They are:[6]
- C. parviflorum var. exiliens Sheviak – Alaska
- C. parviflorum var. makasin (Farwell) Sheviak – commonly called the "northern yellow lady's-slipper";[7] widely distributed over much of Canada and the northern United States
- C. parviflorum var. parviflorum – commonly called the "small yellow lady's-slipper";[8] southern part of the species range, from eastern Nebraska and eastern Oklahoma east to Virginia and New Hampshire
- C. parviflorum var. pubescens (Willdenow) O. W. Knight – commonly called the "large yellow lady's-slipper";[8] very widespread across much of United States, Canada, and St. Pierre & Miquelon; treated by many authors as a distinct species, Cypripedium pubescens
C. parviflorum var. parviflorum, showing pubescent bract and dark maroon sepals
C. parviflorum var. pubescens, showing yellow-green sepals spotted with maroon
