178 PENTANDRIA. DIGYKIA. 



each with 3 marginated dorsal rihs, and 4 

 obtuse-angled grooves. — Involiicriim about 5- 

 leaved. 



. A small succulent, repent plant: peduncles axillary, uni- 

 bell many-flowered; leaves sessile, cu;ieate-linear, with 

 5 transverse nerves (or dissepiments.) Nearly allied to 

 Jizorella, but of a very different habit.

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

 o lines wide, and about 2 inches lonp;-, succulent, smooth, 

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

 with 5, rarely 6, transverse lines, approximating- upwards, 

 longitudinal vessels obsolete. Umbells simple, solitary, 

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

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

 dicellate, unifoim; calix marginal or obsolete; petals 

 roundish-oval, obtuse, rosaceous. Stamens much shorter 

 than the petals; antb.ers roundish. Styles very short, re- 

 curved, each with an elevated roundish base, forming 

 almost half 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? inteuially 

 concave, having 3 margined dorsal ribs or elevated lines, 

 exclusive of the commissure; intervals smooth. 



Hab. From T7e\v Jersey to Florida, in salt marshes? 

 (Abundant near Egg-harbour, New Jersey, in a ?,^X.- 

 vc\^x%\\ \v\V(\ Limnetis juncen^ &.c.) Flowering time, from 

 May to September. 



To this genus probably appertains Hydrocotyle Mnifolia, 

 and H. vivgata, which are certainly distinci from the pre- 

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