Amazing how many Orchids there are in MI! Again, per Dale!

In this posting, we will display three species of Twayblades from two separate genus', Liparis and Listera. Twayblades are very easy to walk by and not even notice them. They are small and have unusual flower forms.

The first orchid is Listera cordata, or Heartleaf Twayblade. This orchid can be very small, but not always. Found on dry sand and in mossy bogs. May be green or reddish in color. One of the widest ranging of all of our orchids. Pictured here from Alger Co., they stand
2 1/2" - 10" tall. Cold bogs, swamps, and woods. It is easier to locate the two small basal leaves than it is to look for the flower itself.

Listera auriculata, or Auricled Twayblade favors streamside areas in mossy surroundings. Pictured here from Alger Co., it stands 2 3/4" - 7 1/2" tall. A rather unique translucent orchid. Very rare and local in our area. This differs from the Broadleaf Twayblade in an earlier post, in that the flower is narrower and the grove at the end is much deeper than the Broadleaf.

Loesel's Twayblade (Liparis loeselii), can be found statewide. The yellow green color often conceals it in sedges or other vegetation. Can be very small 1 1/2" to 10" tall, although I have seen this orchid up to
20 ". Likes damp meadows, lakeshores, sedge mats and sphagnum bogs.
