Identification of the Juveniles of Some Ferns from Western Amazonia

Published 1995 in American Fern Journal

ABSTRACT

In floristic inventories and ecological studies it is often desirable to collect and identify all individuals of the plants involved. This is necessary if the total number of individuals is to be counted, or if the age structures of populations are to be clarified. Identification of juvenile plants in the tropical rain forests is difficult, and ferns are no exception. Both fern floras and monographic treatments concentrate on describing adult plants, and all identification keys are based on adult material. Usually it is even necessary for proper identification that fertile leaves are present. The fertile-sterile leaf dimorphism has been described in detail for those species in which it is found, but differences between juvenile and adult stages have been treated only occasionally. One obvious reason for this is the lack of juvenile collections in herbaria; both general collectors and herbarium curators tend to prefer fertile material. For a few fern species, the anatomical development of the juveniles has been
