Twenty-two species of this genus are here recognized. They have been sepa- 

 rated into many genera by various authors, as the list above given will show, I)ut 

 according to my view, the species constitute only a single genus, composed of vari- 

 ous groups, no one of which exhibits generic characters of sufficient importance to 

 separate it from the rest.
