STEVIA micrantHa, Lag. Nov. Gen. d Sp. p. 27. S. macella, Gray, Pl. Wright, 2, p. T0. Cobre =~~ 
(Copper Mines,) New Mexico; Wright. This being the same as a plant collected by Schaffner 
Ч on Chepultepec, and kindly communicated to me by Dr. Schultz, the distinguished investigator 
i of Compositæ, under the name of S. micrantha, I do not hesitate to restore that name, although 
the specimens do not altogether accord with Lagasca's brief character.
