BryacecE.—This family includes the vast majority of the Mosses. The germinat- ing spore produces a simple, branching, filamentous protonema (figs. 398 ^ and 398 ^) on the surface of the ground, certain of its branches developing as colourless rhizoids and penetrating the substratum. From the protonema the ordinary leafy Moss-plant arises as a lateral bud (cf. fig. 398^). The curious properties of the protonema of the Luminous Moss {Schistostega osmundaoea) have been already described {cf. vol. i. p. 385, and PI. I. fig. p). The leafy shoots become rooted by the development of rhizoids from their lower extremities, and bear their leaves, as a rule, in three rows, though a slight twisting of the stem often disguises this Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Kerner von Marilaun, Anton, 1831-1898; Oliver, F.
