Book Description
Excerpt from The Ferns of Great Britain, and Their Allies the Club-Mosses, Pepperworts, and Horsetails A popular description of a fern might be, A large leaf or branch of leaves, bearing no flowers. Yet that leaf-like spray differs from a leaf in several particulars of structure; the most marked of which is, that it repre sents the leaf and fruit conjoined, bearing its fructifi cation, in most cases, on its under surface. The word fmnd, therefore, applied to the green expansion of a fern, though it originated in the idea that the leaf of a fern was composed of a branch and a leaf, is not alto gether an unnecessary distinction. The frond consists of two parts; the leafy portion and the stalk. The stalk is often called the rachis, but, strictly speaking, it is composed of two parts. That part which bears the green leaf is the rachis; and the lower portion of the stalk, destitute of the green expansion, is the stapes. When the frond is so divided, that, besides the principal stalk, another set of stalks runs through the green di visions, each of these last is a secondary mchie; the term primary mchz's referring to the main stalk.
