Two pairs of vicarious species of Cypripedium (Orchidaceae) from eastern Asia and eastern North America [Cypripedium reginae and Cypripedium flavum and the other pair Cypripedium arietinum and Cypripedium plectrochilon]

The taxonomy and phytogeography of two pairs of vicarious cypripediums, C. reginae Walt. and C. flavum Hunt & Summerh., and C. arietinum R. Br. and C. plectrochilon Franchet, are discussed. They are all distinct species, though there exist close relationships between the members of each pair. Or...

Description
Summary:The taxonomy and phytogeography of two pairs of vicarious cypripediums, C. reginae Walt. and C. flavum Hunt & Summerh., and C. arietinum R. Br. and C. plectrochilon Franchet, are discussed. They are all distinct species, though there exist close relationships between the members of each pair. Or phytogeographic interest are the strong resemblance of distribution patterns of these two pairs of vicarious species, the similarity of their habitats, and the fact that all are rather primitive members in the genus.
