Heart-leaved Twayblade / Listera cordata var. nephrophylla forma rubescens

This is one of the smallest and most difficult flowers I ever get to photograph : ) I took about 25 photos of two or three different ones and this was the last I took and the only one to come out even remotely OK. The top flower of this wild Orchid does show the split blade reasonably clearly, though. Seen on the Sarrail Falls trail, Kananaskis, at Upper Kananaskis Lake on July 8th. If I remember correctly, I've only seen this species in a couple of different locations.

This is a native, woodland species, only a few inches tall, and not easily seen. Each flower is only 3/16 inch across and the plant blooms June-August. The flowers are pale green to purplish-brown in color, with the lip divided for more than half its length into 2 linear lobes with a pair of horn-like teeth at the base. There are two varieties, one with pale green flowers and the other with purplish-green flowers (as in my macro photo). I think I'm correct in saying that my photo shows Listera cordata var. nephrophylla forma rubescens.
