Lesser Butterfly-orchid

Platanthera bifolia


Medium sized (about 30 cm tall) perennial flowering plant with with flowers grouped in loose inflorescence. Flowers are white, and the upper sepal and petals form a loose triangular hood above the pollinia, which lie parallel and close together. The lip is long and narrow, with two lower sepals forming sort of wings some 2 cm wide from tip to tip. Spur is very long, straight and horizontal. Easy to confuse with greater butterfly-orchid (funny - they are both about the same size), but for the angle of polinia; and by the only two broad, rounded and shorter basal leaves.


Alpine meadow, protected natural reserve of Haut Jura. We observed many orchids, but only three of this species.
