Descript. Stem creeping-, terete, filiform. Leaves 2or 

 3 hues wide, and about 2 inches lont^, succulent, smpoth, 

 erect, cuneate-linear, obtuse and sessile, each marked 

 with 5, rarely 6, transverse lines, approximatin^e; up\<ards., 

 longitudinal vessels obsolete. Umbells simple, solitary, 

 axillary, 8 to 12 flowered, peduncles a little longer tliau 

 the leaves. Involucrum 5, rarely 6-leaved. Flowers pe- 

 dicellate, uniform; calix marp'inal or obsolete; petals 

 roundish-oval, obtuse, rosaceous. Stamens much shorter 

 than The petals; anthers roundish. Styles very short, re- 

 curved, each with an elevated roundish base, forming 

 almost lialf the germ, which thus appears as if cut round, 

 about the middle. Fruit nearly spherical; commissure 

 (or interior surface of junction) suborbicular, and de- 

 pressed, with a thick suberose, connivent margin. Seeds 

 convex, unequal, one of them often abortive? internally 

 concave, having 3 margined dorsal ribs or elevated lines, 

 exclusive of the commissure; intervals smooth. 



Hab. From Nfew Jersey to Florida, in salt marshes? 

 (Abundant near Egg-harbour, New Jersey, in a &7i\\.- 

 msivsh with Limiietisjiuiceay Sec.) Flowering time, from 

 May to September. 



To this genus probably appertains Jlydrocotyle linifolia^ 

 and H. virgata, which are certainly distinct from the pre- 

 sent species, considered, however, the same with //. sinen- 

 sis by the editor of Kees' Cyclopedia: see Uy drocotyle.
