190 PENTANDRIA. DIGYNIA; 
~ stem; leaflets 5 or 6 inches long, and about 2 lines wice, 
‘thickish, perfectly entire, or now and then, but rarely, 
bifid, circumscribed by a white and somewhat scabrous 
_, Margin. Umbell rather small, with elongated rays. Um- 
bellets roundish, with sessile abortive flowers, involucell 
many-leaved, filiform-subulate. Calix distinct, 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. peucedanifolia of Europe. Hau. On the marshy banks 
of the Delaware, near Philadelphia. My friend Z. Col- 
‘ lins, Esq. informs me, that this plant attains the height of 
6to 10 teet in the marshes of New Jersey, and that the 
= lower leaves are extremely long and furnished with nu- 
_ (merous leaflets, uniformly narrow like those of the Dela- 
eS wate plant.—These 2 — do not well accord ‘with the 
+ genus, and appear allied somewhat to Peucedanum, by 
_ the flatness of the seeds. Iam satisfied that the celebrated 
Sprengel could not possibly have referred our G. rigidiua 
to his genus Sivm; one of us must be in an error as to 
the identity of the plant. 
OF this noxions genus there are about 12 species in Eu- 
rope, Lin Barbary, 1 in tropical America (Hwanaca acaulis, 
Cav.) 6 at the Cape of Good Hope. According to Per- 
soon the tuberous roots of (£. peucedanifolia are eaten by 
children in some parts of France.
