190 PENTANDRIA. DIGYNIA. 



stem; leaflets 5 or 6 inches long, and about 2 lines wide, 

 thickish, perfectly entire, or now and tlien, but rarely, 

 bifid, circumscribed by a white and somewhat scabrous 

 maig-in. Umbeli rather small, with elongated rays. Um- 

 bellets roundish, with sessile abortive flowers, involucell 

 many-leaved, flliform-subulate. Calix dislinct, 5-toothed. 

 Petals cordately-inflected. Styles very short, peltately 

 dilated at the base. Fruit smooth, flat, and subelliptic. — 

 Nearly allied to the preceding- species, and probably to 

 (E. peucedanifoHa of Europe. Hab. On the marshy banks 

 of the Delawaie, near Philadelphia. My friend Z. Col- 

 lins, Esq. informs me, that this plant attains the height of 

 6 to 10 feet in the marshes of New Jersey, and that the 

 lower leaves are extremely long and furnished will) nu- 

 merous leaflets, uniformly narrow like tliose of the Dela- 

 ware plant. — These 2 species do not well accord v, ith tiie 

 genus, and appear allied somewhat to Peiicedanumy by 

 the flatness of tiie seeds. I am satisfied that the celebrated 

 Sprengel could not possibly have refei-red our (E. ri^idins 

 to his genus Slum; one of us must be in an error as to 

 the identity of the plant. 



Of tiiis noxions genus there are about 12 species in Eu- 

 rope, 1 in Barbary, 1 in tropical America {HuujiacaacauUsf
