Three Birds Orchid  or Nodding Pagonia Triphora trianthophora
  
Three years  ago  while taking a group of Girl Scout Leaders on a little ride showing off the area as a potential Camporee site we happened along a clump of flowers which I had never seen before.

There were literally hundreds of tiny blooms which had the appearance of tiny orchids.   I had forgotten my camera and could not find the flowers a couple days later when I came back with the camera.

 

3 weeks later when visiting the same area I came upon a large clump of what appeared to be pods.  I was able to get some pictures & at that point we were able to identify it as 3 Birds Orchid or Nodding Pagonia
 
The following  year  I made nearly daily visits  to the clump so that I would be sure  to be there on the one day of the year they are supposed to bloom.    Here's a close look inside at the stamen from below
 
I could find only 2 pictures on all the web and they were of the same single plants, at a distance

  It is threatened throughout the US with about 20 sites found in Wisconsin,
 
It is found from Maine to Texas &  Minnesota to Florida.  In Wisconsin it is found mostly in Green county discovered first by Curtis himself in the 1930's.   This is the only new site found in Wisconsin since 1990.
 
Information from the State Endangered Species people was very interesting but seemed to disagree with many of the findings we were able to notice.  .First, nothing was said about the plants growing in clumps and since all pictures were of single plants it suggested a solitary plant, not the colony or clump seen here.
 
Second it stated that the plant bloomed for one day only and that all the flowers on one plant would bloom the same day.  In fact we had 3 different 1 day blooms during the month of August.  In 2001 there were 5
days that had at least one flower bloom.  All Blooming days were preceded by a weather change which often included rain but always included a temperature drop of at least 30 degrees F within  24 hrs.  Blooms
occurred 48-72 hours after a significant rain of 1" or more or were associated with a big temperature drop.

 

 

 

 

 

 

 

The first picture is of the first  bloom the second picture is of the second bloom with some of the seed pods apparent from the first bloom. 

         Thirdly it stated the pollinator was the Bumblebee.  Since the flower was extremely small, usually less  than 1 cm across, I could not imagine how such a large bee could pollinate such a small flower.  Several times small bugs could be seen crawling in and out of the flowers.  It turns out there are several sub-species one of which found in Michigan is much smaller than  other sub-species.  This may represent that varient or may represent a new sub-species.  DNA testing is currently being done by a PHD candidate at Ohio State.  His Thesis will be a link when finished.  His testing may show this to be a new sub-species.

This picture shot by my daughter for a 4H project shows a Black Gnat or some type of extremely small fly in the act of pollination.  Notice how the fly  grasps the stamen as it dips into the lateral recesses for nectar.  Pollen attaches to the fly's feet  and pollination occurs when the fly turns around walks out of the orchid and then flies to the next flower and repeats the process

   

Here you can see flowers just opening with many developed seed pods. This is Bloom #3 with many of the seed pods growing out of the first round blooms that occurred almost a month earlier  Usually only 1 of the 3 birds flowered at a time with only about 5% of the plants having multiple blooms active on the same plant at the same time.  At the end of the blooming period only 1 of more than 100 plants had 3 seed pods on it indicating of all the plants present only 1 was able to get all 3 birds to bloom and form seed pods.   Most had 2 pods and many had only 1.
