 wedge-shaped cut nearly equal, involucre of many leaves. 

 Liglitf.p. 162. E. B.t.23\3. 



HAB. Banks of ditches, rivers and lakes, frequent. FL July. 7/ . 



Three to five f. high. Distinguished by the broad leaflets even in the 

 very uppermost leaves. Umbel rather large. 



B. Umbels with a partial involucre; universal none.

 ing. Leaves thrice pinnate or rather pinnatifid ; segments small, 

 lanceolate, spreading, dark green. Umbels opposite to the leaves, 

 rather small. The genus scarcely differs from (Enanthe but in the 

 want of a general involucre : a very unnatural character ; and 

 this is, consequently,, the (Enanthe Phellandrium of Decandolle.
