Discussion:
This genus, which is very abundant in the Bolivian Andes, has come to be abundantly represented in herbaria, especially in that of The New York Botanical Garden. One or more of the collections made by the author in 1886 and 1887 were referred by Dr. Britton to F. salicifolia Presl, which, in the flowering state, they very closely resembled. Later collections, made by M. Bang and others, very closely resembled the former. Not being well enough acquainted with the genus to know its tendency to variation within the species, F. salicifolia was regarded as a variable species, with many varieties or forms. A careful study of the material that has now accumulated under this name shows clearly that this view was erroneous, and that we have a group of species closely resembling one another, not one of them apparently representing the species to which they have been referred. F. salicifolia is a species of southern Brazil, and probably does not occur in Bolivia, being distinguished from all Bolivian species that I have seen by its strongly muricate fruit.
