The Slipper Orchids
Cypripedium fasciculatum: Clustered lady's slipper
The Clustered lady's slipper occurs in eight western states from the Pacific Northwest to California, north to Montana and east to Colorado and Wyoming.
Cypripedium fasciculatum is a small plant with two broad, opposing leaves. The flowering stem may bear one to nine flowers that droop. When the flower goes to seed a capsule forms and the stem becomes erect. The sepals are purple-green and the pouch yellow-green streaked with purple. The small flower is pollinated by a tiny wasp.
