Previous - Next

The leaves of flowerless plants, such as ferns, are generally called fronds ; and the wood of such as have arborescent trunks, such as the tree ferns, is of the kind called Acrogenous, and is formed by the cohesion of the bases of the footstalks of the leaves, or fronds, round a cellular axis. In the structure of mosses, neither vessels nor woody fibre are employed ; their stems are of the kind called Thallogens, and consist entirely of elongated cellular tissue. A'lgï¾µ and Fungi form the lowest orders of flowerlwss plants, and their structure consists almost entirely of cellular tissue.
