O. prcetermissa Druce prevailed. In most of the latter a few plants 

 with spotted leaves occurred, though I could not appreciate any other 

 difference to warrant the suggestion of hybridism with O. Fuchsii 

 Druce. Actually I only found the latter in Shingham Fen with 

 O. prcetermissa. Accustomed as we are here to regard Hahenaria 

 Conopsea as a plant of the downs, it Avas curious to find it coming 

 right down into the bog at Caldecote with Aquilegia vulgaris : —
