. Dansk botanisk arkiv. Plants; Plants -- Denmark. Fig. 305. Lophocladia trlchoclados (Mert., C. Ag.) Schmitz. Part of a fila- ment with trichoblasts. (About 45:1). cell is still short, though somewhat longer. The first side-branch of the trichoblast is that which is trans- formed into the stichidium (comp. Figs. 306 and 307). In the fully developed trichoblasts the cells are long and cylindrical, about 23 n thick and 250 u long, somewhat shorter and thicker towards the bottom, longer and thinner towards the top. Exogenous branches formed in the summit of the plant seem to be entirely wanting.

Exogenous branches formed in the summit of the plant seem to be entirely wanting. I have looked for them in vain, and Falkenberg did not find them either. The ramification of the plant takes place by means of endoge- nous, adventitious branches, formed la- ter. The segments in the main filaments are about 175 p. broad, being scarcely double this length, about 270 u long. In the upper young parts of the filaments no cortical layer is present; the older parts of the filaments on the other hand are more or less covered by cortex. The first beginning of the cort- ical layer is formed by rhizoids growing. Fig. 306. Lophocladia trlcho- clados {Mer t., C. Ag.) Schmitz. Young trichoblasts near the summit of a filament, show- ing development of stichidia. The uppermost one is still undivided,the following con- sists of four cells, the lower- most of five.
