Detailed Information

Flower: Flower shape: irregular Cluster type: raceme

[photo of flowers] A raceme of 3 to 19 glowing, greenish yellow flowers, less than ½ inch long. Flowers are a spidery array of 3 pale sepals and 2 thread-like petals set about a wider, curled lower lip and a pollinia tipped center column

Leaves and stem: Leaf attachment: basal Leaf type: simple

[photo of leaves] There are 2 basal leaves, oblong-elliptic, gently pointed, 1½ to 9½ inches long, up to 1½ inches wide, glossy on the upper surface, and sheathing lower stem. Leaves and stem are hairless. The stem is angled.

Notes:

The leaves might be confused with L. lilifolia, but Loesel's Twayblade is almost always on wetter sites. Note that the “postage stamp” remnant where some of these images were taken is dying, due to deer food clover mix from a sportman's department being carelessly tossed on it. So not only is the deer overpopulation problem made worse, but the site is now being overrun with weedy invasives. It just goes to show that good intentions can backfire if there isn't much thought put into it.

I think I may have spotted this plant at Uppgaard Wildlife Management Area. Didn't see any leaves but leaf litter surrounding it so they may be hidden. Going back to check it out!
