We can add little to the description in Withering from
that excellent observer Colonel Velley, who discovered this
species on the beach at Weymouth at low water, and whose
melancholy fate we have now to deplore. Our specimens grew
entangled upon Fuel and Confervas, twisted together like
worms, and are simple, cylindrical, bluntish, very viscid when
fresh, adhering to each other when dry. They are very pale
and pellucid, sprinkled all over with blush-coloured dots,
which seem to contain the seeds, and which Colonel Velley
found to turn afterwards to an orange hue.
The fronds vary from 2 or 3 to 12 inches in length, and are
about 1 eighth of an inch in diameter.
