Species: Cypripedium fasciculatum
Encyclopedia of Puget Sound
Clustered Lady's-slipper is a perennial with densely hairy, solitary stems, which are 5-20 cm tall and arise from a rhizome. There is a single leaf wrapped around the base of the stem and one pair of sessile, opposite leaves located near the top of the stem; these leaves are broadly elliptic to oval-shaped and are 4-8 cm broad. The 2-4 flowers are tightly clustered at the top of the stem, and each is subtended by a green, lance-shaped bract. The 3 narrowly lance-shaped sepals are 12-25 mm long and greenish brown to purplish with purple lines or spots; the lower 2 are united nearly to the tip. The 2 upper petals are similar to the sepals in shape and color; the lower petal is pouch-shaped, shorter than the sepals, and greenish yellow with brownish-purple margins and often a purple tinge. The ovary and mature capsule are densely hairy.
