long, 1 -3 lines in diameter, cylindrical, very elastic, firmly gelatinous or
somewhat cartilaginous, generally forked near the base, and repeatedly
forked at long intervals upwards, but varying much in the degree of fui'ca-
tion. Axils all remarkably wide, and rounded ; apices but slightly tapered,
blunt. Axis about one fom’th of the diameter of the frond, very dense,
compared by Agardh to a column, and by Carmichael to a “ medullary
cord ” , composed of closely adherent slender filaments, from which issue
the long, horizontal, dichotomous filaments of the peripheiy, whose lower
ramifications ai-e colouiiess, with subcylindrical joints; theii- upper, and
terminal, coloured and beautifully beaded. Occasional reflexed, root-like
