Vegetative Part

(Gametophyte)

The structure of the leafy-mosses is mostly very simple. The leaves are generally but one cell thick from surface to surface, except along a line from apex to base where they form a mid-vein (costa).

The leaves have no epidermis and no breathing pores as do the leaves of higher plants.
