1. Atriplicifolia.

leaves on petioles, gla- 
brous, glaucous under- 
neath, those of the root

Root perennial. Stem erect, three to eight feet high, branching, glabrous, 
somewhat glaucous. Leaves cordate, almost reniform, the upper ovate, 
rhomboidal, and lanceolate, all sinuate, with the summits of the lobes acute, 
sometimes dentated and glaucous underneath. Flowers in small terminal 
corymbs. Peduncles almost white, clothed with small subulate pale or 
colourless scales. Involucrum composed of five equal, linear, three-nerved, 
glabrous, colourless leaves, containing five flowers. Corolla tubular, whit- 
ish, tinged a little with purple. Styles bifid. Stigmas glandular. Seed 
oblong, glabrous, obovate. Pappus hairy, scabrous, very white. Recep - 
tacle naked, with an irregular angular somewhat glandular mass in the cen- 
tre. This mass, composed perhaps of soldered scales, is generally three- 
cleft at the summit, curved at base, as if embracing the stems of the florets, 
but of three more distinctly than the other two. 
Variety Angulata. 
I have specimens collected in St. Thomas’ and in the middle districts of 
Carolina, in which the leaves are nearly round, deeply and acutely divided 
into seven or more lobes, the lobes sometimes dentate, in other respects 
agreeing with this species. 
Grows generally in rich soils.
