Organism information awaits expert curation
Class: Phaeophyceae

Plants forming low tufts. Basal creeping system endophytic, composed of more or less irregularly bent and ramified filaments, free at first and not coherent; later growing over and in between each other become felted together. Cells of the creeping filaments 7-35 µ long and 8-17 µ broad. Erect system composed of long or short filaments, the former upto 450 µ high and the latter rarely more than 250 µ in length. Filaments 7-15 µ broad cells of the filaments richly provided with lobed chromatophores. Definite meristematic region lacking, but cells in the lower region of the filaments divided now and then.

Plants bearing only plurilocular sporangia; the latter either terminal or lateral. The terminal sporangia produced on short filaments, oblong-subcylindrical in shape, upto 85-105 µ long and 23-30 µ broad. Lateral sporangia produced on long filaments, sessile as a rule, occasionally pedicellate; ovate-oblong in shape, about 50 µ long and 20 µ broad.

Epiphytic on the surface of Padina tetrastromatica and Sciania indica.
