Chiefly an European genus of ground orchids. 

 Seeds, as in Ophrys, when obtainable ; division 

 of the tuberous roots, though they do not relish 

 transplanting well ; it should be done when the 

 plants are in a dormant state. The British 

 species are chiefly found on chalky hills, and in 

 pastures where calcareous matter abounds. 

 The exotic kinds like an addition of fibry peat. 

 The tender ones, in fact all, when cultivated, 

 should be treated as Alpines ; those found in 

 rich pastures require a moister situation.
