F o u n d on submarine rocks and stones, chiefly on the
south coasts of England. Our larger specimen was gathered
in the isle of Wight by Miss Everett; the smaller, which
seems Mr. Stackhouse’s F.,pusilltts, Ner. 16. t. 6, Mr. Borrer
found at Brighthelmston. Lightfoot says this species is met
with “ in the Frith of Forth, and other places, but not
common.” It is said to bear fruit in the summer.
The fronds form entangled tufts, of a light red or tawny
hue, with a waxy transparency, and when dry a horny elasticity.
They are repeatedly branched, the branches lanceolate,
very regularly, and more or less deeply, pinnatifid or pectinate,
sometimes simply, often doubly or triply, hence the various
species of authors which can hardly be defined as varieties,
comprehending the pinnatus and Jilicinus of Hudson, 586,
the spinosus of Gmelin, t. 18. ƒ. 3, and, as Mr. Turner
suspects, his capillaceus, t. 15. ƒ . 1 . With this last we are
unacquainted. The seeds of F. corneus are lodged in the
tumid oval extremities of the lateral segments.
