The Composite here figured has been in continuous 
greenhouse cultivation for over seventy years. A native 
of Central America, it is met with wild at from 3,000 to 
6,500 feet above sea-level from Southern Mexico to Costa 
Rica. The monotypic genus Podachaenium to which it 
belongs is rather closely related to Verbesina, Linn., but : 
readily distinguished by its uniformly opposite leaves = 
its stipitate achenes with few pappus scales. When first 
Juzy, 1913.
