Sweet-Scabidus is as common a plant in the United States, as

growing with it. Its geographical distribution, therefore, throughout 
our States, is the same as that of the E. Philadelphicum. By the 
common people, the two plants are distinguished by the names Sca- ©

species under consideration, as-well as to the E. Philadelphicum. -

cies, It sends up from three:to five stems, which are very much . . 
branched above, and attain the height of two or three feet. The ae
