Polysiphonia hapalaoantha Harv. Her. Bor.-Am. 2: 39. pi. 18 G. 1853'
densely tufted, soft and very flaccid; filaments setaceous and cor-
ticate below, much attenuated and articulate upwards, the terminal divisions
almost byssoid, sub-dichotomously decompound, fastigiate, the lower axils pa-
tent; upper branches less regularly forked; all the branches furnished with
minute, simple, scattered, spinelike, quadrifarious ramuli, and copiously
clothed with byssoid (deciduous) fibres; articulations in all parts of the
frond about at long as broad, four-tubed, those of the larger branches with
supplementary cellules.

Hab. Key West, Dr. Blodgett! (v. s. in Herb. T. C. D.)

Filaments four or five inches long, branched from the base in a
more or less regularly dichotomous order, the lower forks pretty regular, the
upper, by the frequent suppression of an arm, subalternately decompound. Tfe
filaments are greatly attenuated upwards, the lower parts being thicker than
hog*s bristle, the upper branches much finer than human hair. Axils, es-
pecially the lower ones, patent. Spine-like, simple ranaili, one or two
lines in length, and spreading to all sides9are freely scattered over the
•segments at distances of a line or two. Our specimens are copiously fibri-
lliferous. The articulations are uniformly short; those of the upper divi-
sions marked with two broad tubes, those of the lower successively coated
with secondary cells, but not obliterated. Colour, when dry, a Vandyke
brown. Substance very soft. It closely adheres to paper.
