A chap with a big camera was grovelling on the grass looking for rufous grasshoppers said he'd seen one frog orchid on top on one of the dozen or so hillocks, & his camera recorded longitude & latitude, but only to within a few dozen yards. He'd also seen 1 musk, I beat him & found a small cluster, they're a bit subtle, grass coloured and small even by British orchid standards,but wonderful. I suspect they're a bit less rare than the books say as so easily missed.
He spent some time looking for the frog & eventually tracked down the right hill, technology has its uses! After a short time grovelling this little treasure revealed itself. Just one, in spite of our search for one of our own. Many thanks to the anonymous enthusiast!
That makes ten since I got my new camera, only 45 or so more!
