around New-Haven, Connecticut. Prof. I-v e s. On the banks 

 of the Delaware near Philadelphia. jYu 1 1 all. On the shores 

 of the Hudson near Albany, New-York. Eaton. August. 

 A singular little plant, allied to Montia ; very properly 

 erected into a new genus by Nuttall, who has admirably illus- 

 trated it in the Journal above quoted. It is probably widely- 

 spread over the country, though not easily detected on account 

 of its minuteness. I have specimens from Mr. .Yu ttall^ 

 which he collected more than a thousand miles up the Mis- 

 souri. First discovered by Prof. Iv e s, of New-Haven, who 

 called it Dwightea, but never published a description.
