As Rafinesque pointed out this American genus is sufficiently 

 distinct from the old world genus Olja Adans. { = Isopyrum Linn., 

 not Theophrastus and of the pre-Linnaeans). The American plant is 

 always devoid of petals. The European and old-world Isopyrum 

 Linn, has 5 nectariform or slightly sac-like petals. The old world 

 plants are thus intermediate between Enemion Raf . on the one hand 

 and Aquilegia on the other.
