An orchid - 175 years later

A diminutive club-spurred orchid, Platanthera clavellata, juts from the shady gloom of the forest floor at Cedar Bog. I made these photos yesterday, and will apologize up front for their relative lack of quality. I was helping to lead a field trip for the Botanical Society of America, and didn't have time to set up these shots in the manner in which I would have preferred.

I've written about Cedar Bog many times, including several times this year. It has been a banner season for orchids at "the bog", and now the club-spurred orchid can be added to the roster. HERE IS an earlier post about Cedar Bog's showiest representative of the Orchidaceae family.

One of the botanists that was along on yesterday's field trip was the incomparable Anton "Tony" Reznicek of the University of Michigan. Tony oversees the U. of M.'s herbarium, which is one of the largest in the country and contains some 1.7 million specimens of vascular plants, algae, bryophytes, fungi and lichens. I think something like a million or more of these specimens are vascular plants, such as the orchid featured in this post.

The University of Michigan herbarium houses a number of very old and valuable collections, including some of the first plant specimens collected in the Midwest. These holdings include a series of collections from a gentleman named John Samples, who was the first botanist to make specimens from Ohio's own Cedar Bog. Samples was an Urbana school teacher, and thus lived near Cedar Bog (for a comprehensive biography of Samples, CLICK HERE). From 1836 to 1840, he made numerous collections of plants from this area, at a time when Cedar Bog and other local prairies and fens were far more extensive than they are today.

 Upon his return to Michigan, Tony Reznicek ducked into the herbarium and had a look at some of John Samples' Cedar Bog plant specimens. Lo and behold, there was a collection of club-spurred orchid, with the following label information:

"Habenaria tridentata, Orchis tridentata [old synonyms for Platanthera clavellata]. From the Upper Cedar swamp, August 12th, 1837".

So, exactly 174 years and 11 months later, I photographed this orchid in probably nearly the same spot that Samples collected it, he in the same year that Michigan became the 26th state admitted to the Union. Were it not for the conservation of Cedar Bog, I can guarantee that the club-spurred orchid and most of its neighboring botanical treasures would no longer exist in that area.

I and others are fond of saying that places like Cedar Bog are living museums; places where people can go and see habitats, plants and animals that existed back in pioneer days. The example of this little orchid bears that out.

A beauty!! The orchids are just budding out here! I'm pretty excited. I love thinking about them being so old!! Great post!

Pretty amazing story for Club Spur as I always felt that they jumped around alot and weren't reliable from one year to another. Cool to think that the conditions have remained right in the same area for such a long period of time.

Great post Jim - interesting to think about as in NE OH Club Spurs rarely appear in the same location every year

For a moment there I thought that was a Platanthera Leucophaea and got really excited. Still a nice find though.

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
