NEW MI Orchids from Dale and Ruth!

Postby SandyLee » Wed Jul 08, 2015 4:17 pm

Thanks Dale and Ruth for your great Orchid additions! They are lovely and the accompanying info is much appreciated! :D
Per Dale:
"Ruth and I would like to add a couple of new postings to this collection
of native Michigan orchids. These are additional species or variations
within a species not included in our previous posts.

The first will be Platanthera obtusata, also called the Blunt-leaf Orchid.
This orchid can be found in rich, cold forests and bogs. It has one
leaf at ground level and displays several light green flowers. Found in
the northern part of our State, this was photographed in Mackinac
County. Stands 2" - 8" tall, sometimes larger.


Next will be the Alaska Orchid, Platanthera unalascensis. Much like
birds being moved from one Family to another, this orchid was recently
moved from the Family Piperia to Platanthera. This is another northern
orchid, most likely only found in the Upper Peninsula within our State.
Hard to see in open cedar-balsam woods, this photo was chosen to show
you that. Very small flowers along a spike of 8" - 30". Photographed
in Mackinac County.

Goodyera tesselata is the last of the Rattlesnake Plantain's, the other
three already presented in earlier posts. In all the plantain's it is
good to know the leaf pattern, as these are present before and during
flowering time. This photo from Chippewa County was picked to show you
the formation of the flower. Spikes contain 20 or more flowers. Stands
6" - 14" tall in dryish, upland coniferous woods.

The final orchid for this posting is Platanthera aquilonis or the
Northern Green Bog Orchid. In 1999 Platanthera hyperborea was split in
to two species, P. huronensis and P. aquilonis. P. huronensis was
presented in an earlier posting. There are several differences between
these two orchids, but some of the easiest to notice are that in P.
aquilonis the lip is yellowish and not greenish white, the spur is
strongly forward curved instead of pendant like, and that the spur is
shorter than the lip. P. aquilonis also has no scent, whereas P.
huronensis is fragrant. This orchid stands 2" - 24" tall and likes a
wide variety of wet soils including the wet sands and limestone of Lake
Huron shorelines. This orchid was photographed in Jackson County."

Very cool...thanks for the info and pics Dale and Ruth. I know, since reading all of your posts, that I am much more careful when making my way through the the woods. I'm sure I cannot identify these when I'm out there, but I do watch where I step more than I used to. Thanks again for the info.
