Substance horny-membranaceous, destitute of cal-careous matter. Structure unicellular, the cell (frond) continuous,strengthened internally by a spongy network of anastomosing fila-ments, and filled with a semifluid grumous matter. Fructificationunknown.—Caulerpa {Lamx.), from Kavko<i, a stem, and kpirto, tocreep: creeping surculi are characteristic of this genus.
