Jloot annual. Stem sometimes erect, but generally procumbent, 

 much branched, subangular and sulcate. Leaves about 2 

 inches long, petiolate, of a gray colour, and somewhat mealy 

 on both surfaces, acute at the base, with the lowest tooth on 

 each side produced into lobes; upper leaves lanceolate and 

 entire, or simply hastate, without teeth. Perfect and fiis'.illi-

 racerpes. Stamens 4. Fructferous calyx broad-rhomboid, 

 sometimes denticulate towards the base, pulverulent. 



Hab. In salt marshes, and on the sea-coast ; common. August. 



This species is nearly allied to A. Itastata^ particularly as 



represented in FL Danica t. 1286. The latter, however, has 



' the calyx of the fruit sinuately toothed, and is, \ believe, not a 

 piaritime species, 



4. A. patutit L, : stem herbaceous, sprcadi.ng ; leaves tri- 

 fingular-bastate, smooth above, irregularly toothed : the up- 

 per ones entire ; fructiferous calyx subinuricHle on the side^.
