U L Y A Turneri.
Re ticu la ted Laver.
CRYPTOGAMIA Algae.
G$n. Char. Frond membranous-or gelatinous. Seeds
solitary, scattered throughout its substance, under
the cuticle.
Spec. Char. Membranous, tubular, simple, bluntish,
brown, finely reticulated. Seeds in little clusters.
F o u n d by Miss Hutchins at Bantry bay, and by Mr. W.
Borrer on the Sussex coast. Mr, Turner sent it to Mr. Dill-
wyn, who gave it the above name, in an essay, which, as we are
informed, he has long been preparing, upon this genus.
Several fronds grow together, bearing a considerable resemblance
to U. Jistulosa, t. 642, in general aspect and colour,
being simple, tubular, hollow, tapering at the base, obtuse at the
summit; their substance thin and rather membranous. An
essential difference however consists in the U. Turneri being
throughout of a fine reticulated structure, compared by Mr,
Turner to that of the Conferva umbilical a of the late Colonel
Velley, Tr. of Linn. Sac. v. 5. 169. t, 7. The seeds are dark
'brown, collected together in small spots, over the whole frond.__
Another plant, nearly akin to these two, is Ulva stellata, W ulf.
in Jacq. Coll. v. 1. 351, which is Lichenoides gelalinosum
feme reliculatum, Dill, Muse. 138. t. 19. ƒ . 2 1 .
