An European orchid introduced to the vicinity of Rochester, NY in 1888, now naturalized and widespread in northeastern North America, reaching north to the very Newfoundland and also on the Pacific Coast. All our finds belong to the most widespread green-flowered form (forma viridens A.Gray). This one was growing on a gravel heap at a large trail intersection near Ponkapoag Pond (photo 2005).
