The genus Anomostephium seems made up of very incon- 
gruous materials, it being probable that the four species which 
De Candolle has placed in it are referable to as many diffe- 
rent genera. The ligules are said in the generic character to be 
neuter, but in A. duphthalmoides, DC., figured in Delessert’s 
Icones, they are represented as female; and if correctly so, then 
the plant is evidently a Medelia; while A.(?) oblongifolium, DO», 
seems to be a species of Viguiera, judging from his description of 
the pappus of the immature achenia. In everything but the 
pappus the present plant is a Leighia, which genus I now reduce 
to a section of Viguiera.
