This species is described by Michaux as inhabiting the borders of the 
Ohio and Mississippi. Walter mentions it among the plants of this coun- 
try. It is probable that the following species is the one intended by Wal- 
ter. At least, I have seen no one agreeing with the character of E. Thvmi- 
folia, or with the figure of Plukenet, t. 113. p. 2. It maybe remarked 
also, that the original E. Thymifolia is a native of the East-Indies, 
6, Depressa. Torrey. 
Stem procumbent, 
slender, pubescent; 
leaves opposite, oval, 
slightly serrate; un- 
equal at base, glabrous 
on the upper surface, 
hairy underneath and 
pale; flowers solitary, 
axillary, much shorter 
than the leaf. 
Plant annual. Stem prostrate, branching, 8— 12 inches long, hairy, almost 
villous, branches alternate. Leaves finely serrate, obtuse, sometimes acute, 
somewhat glaucous underneath, about half an inch long, on petioles 1 — 2 
lines long. Flowers solitary, appearing clustered at the extremity of the 
branches, from the shortness of the joints. Peduncles 1 — 2 lines long. Sti- 
pules 4 at each joint, 3 — 4 lines long, plumose; petaloid segments of the in- 
volucrum 4, white, small. Capsule hairy. 
This species has commonly been considered here as the E. Thymifolia, 
Mich.; but its flowers are certainly not in axillary heads or clusters. Dr. 
Torrey sent me some time ago specimens of it from New Jersey, under the 
name of E. Depressa. 
Grows in cultivated dry soils, very common. 
Flowers through the whole summer.

bus, sub-serratis, basi
