empty, in two or three rows ; those of the outer stratum minute, irregularly
placed, and full of coloured matter.
This very interesting piant, by far the most important addition
which has been made to the British Marine Piora since the
commencement of the present work, was discovered on the 21st
October, 1847, by Dr. John Cocks of Plymouth, among rejectamenta
on the shore at Bovisand. A few days subsequently it
was met with in a neighbouring station by the Rev. W. S. Hore,
who at the same time gathered the equally rare and curious
Carpomitra Cabreroe ; and to the untiring perseverance of both
these gentlemen, who, day by day, during the inclement month
of November—in all weathers—visited the shore, and preserved
evei’y scrap of these plants which the waves threw up, we are
indebted for all the British specimens which have yet been taken
of the Stenogramme, and for all, except Miss Ball’s original one,
of the Carpomitra. To Dr. Cocks and Mr. Hore, I am anxious
to express my obligations for numerous specimens of these rare
plants ; and to the latter especially, for much important information
illustrating the history of the present. R is right to state
that Mr. Hore’s observation led to my correcting the error into
which, following Agardh, I should have fallen, of describing the
thickening of the frond, caused by incipient fructification, as a true
nerve. Mr. Hore having found a barren specimen in which no
such nerve exists, established the truth of his view, which he had
previously entertained from other considerations.
The genus Stenogramme was originally proposed by me, in the
‘ Botany of Beechey’s Voyage,’ for a plant found on the coast of
California which strongly resembles the present in habit, and
quite agrees with it in structure and fructification. Strange to
say, according to a specimen preserved in Bory St. Vincent’s
Herbarium, S. Galifornica appears to be a native of Trance also !
English specimens of S. interrupta are broader, less regularly,
and less deeply divided than the figure of a Spanish specimen
given by Montagne ; but I am assured by my learned “ Confrere
en Elore,” that he considers the plants to be identical.
