This species is described by Michaux as inhabiting the borders of the 

 Ohio and Mississippi. Walter mentions it among tlie 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 Flukenet, t. 113. p. 2. It may be remarked 

 also, that the original E. Thymifolia is a native ^f tlie East-Indies.

somewhat glaucous underneath, about hah" an inch long, on petioles 1

 branches, from the shortness of the joints. Peduncles 1 — 2 lines lonj?. 5^/- 

 P^des 4 at each joint, 3 — 4 lines long, phunose; petaloij sej^ments of the in- 

 vohjcrum 4, white, small. Capsule hairy. 



This species has commonly been considered here as the E. Thymifolia, 

 Ijlich.j but its flowers are certainly not in axillary heads or clusters. 

 * orrey sent me some tinie ago specimens of it from New-J^rsov. under the 

 name of E. Depressa. 



Grows in cidtivated dry soils, very comnmn. 



Flowers through the tvhole simjmer.
