Ladylike: Yellow and Purple Lady Slippers. Meet the most fashionable member of Orchid family! Cypripedium calceolus lacks the characteristic pollinia of orchids. Instead, it has a stack of pollens at the end of stamens. However, we are covering these in this series as one of the rarest flowers because these have been uprooted in the U.

There are two varieties of what is called the Greater Yellow Lady's-slipper and they are similar in character. The second variety - Cypripedium parviflorum Salisb. Leaves up to 6 inches long, are ovate and have prominent parallel veins and a base that mostly surrounds clasps the stem; leaf margins are smooth but the surface is hairy. Both stem and leaves of the Cypripedium genus can cause dermatitis. Flowers: Members of the genus Cypripedium have three petals and three sepals.

All rights reserved. Instead it has a mass of sticky pollen on the end of two stamens. The structure of the flower has adapted to its special pollination mechanism. The appearance of the flower attracts many kinds of insects, especially hymenopterans and flies, which are directed towards the yellow labellum. Upon noticing that the flower has no nectar large insects such as bumblebees leave disappointedly the same way they came in via the large gap in the labellum, thus pollinating the plant. The flower is usually pollinated by small burrowing bees which eventually slip or fall inside the sack as they land on the labellum. The edge of the sack is slippy and inclined inwards, so small insects cannot get back out the way that they fell in.

Pick an image for a larger view. See the glossary for icon descriptions. Bright yellow flower column, splashed with purple, broadens into a flat oval lip, appressed tightly into pouch opening. Sepals are similar in color, 2 are fused behind the lip; upper sepal is broader and is erect above the lip. A single leaf-like, sparsely hairy floral bract stands erect at the top of the stem, behind the ovary.

Did you know that in addition to the tall trees for which we are best known, a beautiful and sometimes hidden treasure of wondrous native orchids are on our National Forests and Grasslands? Shy and pale, or flaunting in glorious color, they can be found under trees, in small openings, grassy meadows or prairies. Some are rare or becoming rare. With quality management, the help of our partners, and with your support we can reverse that trend.

A beautiful perennial orchid frequently growing in colonies. The bright yellow slipper, or lip, is a third, modified petal. The petal-like structure behind the lip is actually a pair of fused sepals. Thus there are 3 sepals and 3 petals. Blooms April—June.
