The Lesser-Butterfly Orchid
Specifically different from Greater Butterfly by the position
of the "pollinia", but generally different by its choice of acidic heath and
bog, its smaller size and the fact that it comes out a few weeks later than
its cousin. It is also extremely rare in Dorset - I have only seen a small group in a boggy
part of Hartland Moor, near Poole Harbour.
The "pollinia" in the Lesser Butterfly are allways vertical, parallel and close together.
