I love the color combo!
How about a very confused Laelia anceps? 3 blooms on short stalk in August? It always blooms in Winter for me on long spikes.
Jim, as color comparison - here is my Habenaria rhodocheila opening a bunch of buds now.
edited to correct (communication Leon Glicenstein) - this is Habenaria erichmichaelii and should be fragrant.
