Cluster of Early Coralroot

This is such a tiny wild Orchid and it usually grows in solitary stalks or maybe a couple of plants together. The cluster in my image was huge for this species, maybe 5" or so in diameter. Seen two days ago at Perrenoud Natural Area, NW of Cochrane (which is NW of Calgary).

"There are 3 to 15 flowers in a loose cluster at stem tip; individual flowers about 1 cm long, yellowish-white to greenish or even purple, 6 floral parts with a white lobed lip (occasionally spotted with purple); appearing early summer.....
Infrequent but widespread; in shaded forest habitats, in thickets, fens, swamps and on streambanks; especially on fresh/moist mineral soils."
