Plant from six to eighteen inches high. Root leaves mostly entire, 

 with fleshy footstalks ; those of the stem have from two to six pairs of 

 more or less toothed opposite leaflets, terminated by a larger one which 

 is three-cleft, the upper pair reduced to bractea. Floioers dioecious,

 fugal, and have been long exhibited as a remedy in nervous aff'ections.

 peans, but those of several species arc used in the eastern nations 

 t© aroinatise their baths, and are highly esteemed as perfumes, Cats
