 others ; they are found for the most part in damp

CorallorrJiha. A small genus, found only in 

 Scotland ; it is not remarkable either in form or

The genus NigriteUa has only one species

 that is a native of Austria; it has dark crimson 

 flowers. 



Ophrys. This is beyond question the most in-

Gymnadenia. Four species of this genus are

 fifth ; and an additional one is found in Canada. 

 Viridis is the most common of the British kinds,
