Sorry I haven't a clue....

New location for the Pilates class this morning. We have hired a community room at a sheltered housing development. Newly decorated and carpeted it seemed luxurious compared to the wooden floor of our old venue.

Just a few teething problems as the postie, apologising profusely, walked through the middle and then one elderly resident tried to enter through a door blocked with tables. Signs now made for every entrance!

Back to the little quarry to seek help in identifying this flower. There is only one in amongst a myriad of orchids. Any ideas?
