Pipe Hall Woods Orchids

I made a long overdue visit to Pipe Hall Woods this morning.  I made a bee-line for the meadow to see if there were any butterflies about but almost drew a complete blank.  Where are they all this year?  In the end I did find a couple of common blues, a couple of cinnabar moths and a very pretty orange moth that I couldn't identify.  There were, however, a lot of orchids about.  They were of two distinct types; one being dark purple and pyramidal in shape which I think is the early purple orchid (extra), the other being the one pictured above, more a lilac colour with beautifully formed individual florets and no spots on the leaves.  Can anyone help me with the identification of this please?
