Meetings are always a bit of a chore. One way to make up for the work aspect of such drudgery is to hold said meeting in the midst of beautiful surroundings. And that's what some of us did a week ago, when we convened to sketch out an upcoming conference. Randy Lakes was good enough to host us at his Adams County property, and plenty of good stuff lurked right outside the cabin door. The field above held some Rattlesnake-master, Eryngium yuccifolium, and numerous other botanical goodies.
At first blush, the flowering spike of this one seems thicker, more densely flowered, perhaps one of the double-spiraled species. But, I don't think so. In most respects this species is very similar to the Spiranthes lacera in the first three photos. I think it is the so-called Northern Slender Lady's-tresses, Spiranthes lacera var. gracilis, which at times has been considered a distinct species.
Halleluja, brother - who cares what its name is! An orchid such as this is always a pot at the end of the rainbow, no matter what you call it!
