ches finally dichotomous. The flowers solitary in tin; divisions of the um- 

 bel, small, on peduncles one to two lines long. Fruit tuberculate. 



This species approaches very nearly to the E. Iklioscopia of Europe, 

 although Its roughened fruit and the lanceolate leaves of the umbel may 

 to distinguish it. ' It is, I think, certainly indigenous. 



Found in damp clay soils near the Horse-shoe Bridge, Ashepoo; on 

 - Hutcbmson's Island, opposite Savannah,

Root perennial. Stem herbaceous, about 2 feet high, terete, a little hairy^ 

 rarely branched. Leaves alternate, oval, glabrous on the upper surface, 

 paler and sprinkled with hairs underneath, on petioles 1 — 2 lines long. 

 Flowers in a terminal umbel, each floret solitary in the divisions of the stem, 

 on peduncles 3 — 4 lines long* Petahid segynents of the involucrum more 



conspicuous than usual in this genus, obovate, white. Frtdt glabrous. 



This species varies much in the sixe and breadth of its leaves. I have 

 found it also with 5 rays to the umbel. The following, if no more than a 

 variety, deserved to be noticed. 



Var. Angustifolia* 



Leaves 3 — 4 inches long, linear-lanceolate, sessile as in the common va- 

 riety, paler and hairy underneath. Umbel 3-fid, rays elongated, the upper 

 branches dichotomous. Flowers few, small, thinly scattered near the sum- 

 »*it of the branches. 



Very common, preferring dry soils.
