This is common Newfoundland wildflower but is a rather nondescript little greenish orchid that you would probably step on and never notice. Plants are small and the flowers minute. Its interesting that this orchid pollinates itself, rather than having to rely on an insect pollinator. They grow in bogs, fens and damp depression in open woodland areas, flowering in Newfoundland, in July. It is also called the Club-spur Orchid.
