The old parts of the stolons are almost always naked but provided with number of scars, apparently wart-like processes, which must have been the pedicels of the thick winter fronds. The alternative change of the form regularly takes place at Misaki. But in the other localities the rule seems to be little modified according to the climate and the conditions of the place where the plant grow?. Those plants collected at Suno- saki in December were quite similar with those collected at Misaki in October: those at Shio- misaki in April were entirely wanting of the serrature and had the fronds lineari-spathulate. The specimens collected in a high tide pool at Tateyama, near Snnosaki, in December had the serrature quite obscure and the frond robust? the typical form of G. brachypus. These facts lead us to believe that the seasonal dimorphism in a sense might occur in Caulerpa. The season only, however, is not the factor to cause the change, but the condi- tions of the environs have also some influence upon it. This is proved by the case of Tate- yama. C. anceps, achy pus, and?'.Stahhi are closely related to one another. The principal characters to distinguish them, with those grouped in the section Pliyllantoiaece J. Ag., as formerly remarked, lie on the proliferation, the serrature, the thickness and shape of the fronds. These characters are highly variable and by no means serviceable to separate the species, as Weber v. Bosse has alread}^ men- tionecli*' The three species above mentioned which are separated by the slight differences of these characters become naturally doubtful. A special character of our plant seems to have been overlooked by the former observers / i Fig. 5. 40. .Mon. d. Caul. p.
