In other cases, as in Dudresnaya, the action is less direct—the influence of the antheridian corpuscles being con- veyed by connecting tubes which pass laterally from the base of the trichogynium to numerous fructi- ferous filaments, on which the cystocarps are iinally developed. In Floridese there are also bodies called tetraspores (^rer^dg, four), on account of their being divided into four spore-like organs. These are contained in a distinct sac (fig. 482). They are probably concerned in vegetative and not in sexual reproduction. In the brown seaweeds (Fucacese) there are concep-. 6 Fig. 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 Balfour, John Hutton, 1808-1884.
