(This is a wild hybrid, and was first 

 found near Genoa, and subsequently 

 at Berre, near Nice, and other places 

 on the Riviera, as well as near 

 Trieste and Lucca; and there are 

 dried specimens at Kew from the 

 department of Gers, in France. It 

 must not be confounded with a very 

 closely-allied hybrid between Orchis 

 laxiflora and Serapias cordigera, 

 which has been found as far north as 

 Vaunes, in Brittany. The petals 

 are rosy, tipped with green ; lip aa 

 inch wide, rich purple in colour.)
