 Acapnlco, Guerrero, Mexico, between October, 1894, and March, 1895, 

 Dr. E. Palmer, no. 245 (type, in bb. Gray). This species belongs to 

 S A a ilrniiiiirhid, anil is closely related to L. glabrum HemsL, but it 

 i litters in its much looser corymbose-paniculate inflorescence, its shorter 

 involucre, and much more attenuate involucral scales.

 Deam, do. L94 (type, in lib. Gray). 'This species clearly belongs to the 

 § Andromachia, and appears to be nearest L. gluhnun Ilemsl., from 

 which it may be distinguished, however, by its pubescence and much 

 shorter involucre, the latter scarcely exceeding the achenes.
