Liparis serpens is closely related to L. neuroglossa 
Rchb.f. and L. elegantula Kriinzl. It differs from the 
former in its trailing habit and in the shape of the lip. 
Liparis elegantula, which is very similar vegetatively, 
appears to be constantly bifoliate and to have a differ- 
ently shaped lip.
