* ATRIPLEX HORTENSIS, L.—Gow. Sept. J. Schrenk. 
*A TRIPLEX LACINIATA, L.—At 8th Ave., and Hob. only, with 
A. rosea, June—Oct. Gathered last year at Philadelphia, and 
distributed under the name of A. rosea, from which however 
it strikingly differs in its long (3—10’) terminal spikes of 
(mostly) infertile flowers, and in its more deeply sinuate and 
often pointed leaves, and in itsless spreading and less rigid 
branches. A. rosea, precisely answering to the description 
in the appendix to Gray’s Manual, is very common in all our 
ballast grounds. Its form is everywhere the same—terminal 
spikes of less than 1’, and with rhomboidal leaves, merely sin- 
nate toothed, with very spreading, rigid branches. The con- 
fusion about these two species in some of the books could 
not, I think, arise with our specimens in view
