Publisher's Synopsis

Excerpt from Contributions From the United States National Herbarium, Vol. 20: Part I; The Mexican and Central American Species of Ficus

While many of our species are constant in their characters, some are so variable that two collections may seem to represent quite distinct species until intermediate specimens are examined. Some characters which have been used to separate species are now found to be unreliable. Consequently, it is not improbable that certain species here recognized will have to be reduced when still more ample collections are obtained.
