Leaves green, glabrate as the rest of plant, at least the lower ones opposite, usually 

 hastate or nearly so, only the lowest at times dentate, occasionally linear, petiolate; 

 bracts united at the base only, with dentate foliaceous margins, the sides usually 

 tuberculate or muricate, the teeth occasionally rather small and few; radicle 

 inferior. 

 Leaves lanceolate to rounded-deltoid; plants usually decumbent; pistillate flowers all 

 alike, bracteate. 

 Bracts usually smooth on the face, rhombic-oval, mostly broadly cuneate or nar- 

 rowly rounded at the base; lower leaves rhombic-lanceolate, to narrowly lanceo- 

 late or oblong, not hastate, the upper ones usually entire or denticulate 

 (occasionally slightly hastate), medium-sized, rarely with a pair of basal 



lobes 1. A. patula. 



Bracts ordinarily tuberculate on the face, orbicular-deltoid or ovate-deltoid, usually 

 truncate or broadly rounded at the base, margins mostly with a few toothlike 

 projections; lower leaves rounded-deltoid or triangular-hastate, the upper 

 usually more or less hastate, with basal angles or lobes, mostly large, more or 



less irregularly dentate; inflorescence leafless, spicate paniculate 



la. A. patula var. hastata. 



Leaves linear, not hastate or but slightly so; bracts tuberculate on the face, erect. . . . 



lb. A. patula var. littoralis. 



Leaves gray-scurfy, all alternate, all or most dentate or hastate, never linear, ovate 

 or rhombic-ovate, upper usually sessile, rounded or cuneate at base, cartilaginous 

 on drying; bracts united to about the middle, ovate, acute, longer than broad, 

 fruiting bracts rhombic or cuneate-orbicular, becoming hard and tough with dentate 

 margins, shiny, not apiculate; radicle superior 2. A. rosea.
