Cypripedium fasciculatum Kellogg ex S. Watson
Clustered lady's slipper
USDA Symbol: CYFA
USDA Native Status: L48 (N)
Several short stems in a cluster, each stem with 2 broad leaves and 2-4 drooping, brownish to greenish, bilaterally symmetrical flowers.
Each ladys slipper species attracts insects into its pouch, from which there is only one exit, past the stigma, where pollen from a previously visited flower is brushed off. Then the insect must go under one of the anthers, where new pollen is picked up. This procedure helps maintain genetic diversity, thus increasing the ability of the species to adapt to its environment.
