MOSSES (MUSCI): SPHAGNALES—ANDRE^ALES 163 giving rise to a protonema upon which, as usual, the gameto- phore arises as a bud. In size the gametophore of the Mosses ranges from a milHmetre or less in height in Buxhaumia and Ephemerum to 30 to 50 cm. in the large Polytrichacese and Fontinalis. The branching of the gametophore is never dichotomous, and so far as is known the lateral branches arise, not in the axils of the leaves, but below them. Underground >. i^/M <i^cSz W^4ij^^. Fig. 8

Fig. 86.—Climocium Americanum, showing the formation of stolons, X4. stems or stolons, which afterwards develop into normal leafy axes, are common in many forms, e. g., Climacium (Fig. 86). The sexual organs are borne either separately or together at the summit of the gametophoric branches. Where the plants are dioecious, it sometimes happens that the two sexes do not grow near together, in which case, although archegonia.
