which are in my judgment based on characters which are 
in this genus of specific value only, and indeed in part 
unreliable even for that. I may add that I treat the 
generic name as feminine, which is permissible, regarding 
it as a Greek compound adjective of two terminations, 
that is, with the masculine and feminine forms identical. 
I regard the uncus as always double, though the two parts 
are sometimes closely appressed.
