“ From a cartilaginous disc, strongly applied to foreign
bodies, proceed a great number of close filaments, elastic, of
a brownish green colour, and a little curved at the base;
but they become more pale and straight in the remainder of
their length. These filaments are ordinarily from four to
seven inches in length. Some are entirely simple, the others
throw out here and there branches, or divide towards the
middle of their length.
“ The internodes are oblong, from a line to a line and a
half, cylindrical, and inflated at their points of contact. Their
divisions are often hut little apparent, and disappear towards
the base of the filaments, which appear continuous, cylindrical,
and equal in diameter to a strong horse-hair.
“ The surface of the filaments in old age is encrusted in
such a manner as not to become recognisable either by its
colour which changes, or by the destruction of the internodes,
which become confused and disappear.” — Bory.
“ I have seen this species growing near the mouth of the
Don, very luxuriantly, where it must have been exposed to
the action of salt or very brackish water.” — Dr. Dickie

“ Let us tlien consider the Works of God, and observe the Operations
of his Hands ; Let us take notice of, and admire his infinite Wisdom and
Goodness in the Formation of them : No Creature in this sublunary
World is capable of so doing, besides Man, and y e f we are deficient
herein : We content ourselves with the Knowledge of the Tongues, or a
little Skill in Philology, or History perhaps, and Antiquity, and neglect
that which to me seems more material, I mean, Natural History and the
Works of the Creation; I do not discommend or derogate from those
other Studies : I should betray mine own Ignorance and Weakness should
I do s o ; I only wish they might not altogether justle out, and exclude
this. I wish that this might be brought in fashion among u s ; I wish
Men would be so equal and civil, as not to disparage, deride and vilifie
those Studies which themselves skill not of, or are not conversant in •
no Knowledge can be more pleasant than this, none that doth so satisfied
and feed the Soul; in comparison whereto that of Words and Phrases
seem to me insipid and jejune.” — Ray.

Char. Frond affixed, ramose, articulated. Cells in single
series. Fructification corymbose, involúcrate, and capsular.
“ Except for its freshwater habitat this genus does not
differ from the preceding section of Callithamnion, which in
the ‘ Brit. F lo ra ’ I ventured to unite to it. A t Mrs. Griffith’s
instance I now give up this point, but must still observe
th a t Cal. Daviesii and T. pulchella, when the latter is well-
coloured, are scarcely distinguishable under the microscope.”
