Flex. 208—Commonon fuci within low-water mark.Hoot a creeping thread on the surface of fuci, giving rise to simple orslightly branched stems, seldom reaching 2 inches in height;the joints arebent, and an enlargement at the summit supports the lengthened twistedfoot stalk of a wide cell with an even margin; the tentacula of the polypi areciliated with hairs in whorls ;the vesicles are placed at the base of the footstalks of the cells, above, on short stalks, and nearly of the same shape as thecells, truncated with a central, slightly tubular, orifice.190.
