The plant (Fig. 413) forms small, low tufts upon the host plant, Dictyota indica, from which the longer main filaments protrude. The base (Fig. 414 a) of the plant consists of freely ramified filaments creeping upon the surface of the host and fixed to it by means of quite short, small rhizoids (Fig. 414 b). The filaments have apical growth and the branches are given off from the distal end of the cells at both sides, now alternating, now opposite or sometimes, too, unila- teral. The filaments are mutual

The plant (Fig. 413) forms small, low tufts upon the host plant, Dictyota indica, from which the longer main filaments protrude. The base (Fig. 414 a) of the plant consists of freely ramified filaments creeping upon the surface of the host and fixed to it by means of quite short, small rhizoids (Fig. 414 b). The filaments have apical growth and the branches are given off from the distal end of the cells at both sides, now alternating, now opposite or sometimes, too, unila- teral. The filaments are mutually free. The cells in the basal filaments contain well developed chromato- phores; the cells are about 10 |a broad and 20 ju long. From the cells of this base the different erect organs are given off, namely: short branchlets, hairs, long main filaments and more rarely plurilocular sporangia (comp. Fig. 413 a and 414 a, b). The short branchlets are commonly unbranch- ed, nearly cylindrical with obtuse apex, composed of about six cells reaching a height of about 150 p. and a breadth of 12 //, more rarely ramified. The hairs have one or two basal cells of which the lowermost is the Fig. 413. Myriotrichia occidentalis longest; above these Cells the growth nov. spec, a part of a, plant with ^^^^ follows.
