The real E. Dombeyannm DC. (see p. 11) is probably a Peruvian 

 plant, with roseate or purplish corollas. Its leaves, while of similar 

 form, have decidedly more salient teeth and relatively shorter petioles. 

 These in E. Dombeyanum are about one-eighth as long as the blade, 

 while in E. psUodorum they are more than one-fourth its length. To 

 E. psUodorum may be referred with scarcely a doubt also Dr. Pennell's 

 no. 3190 from Murillo, Dept. Tolima.
