two inches in length. Fructification ; minute, depressed, spherical favellidia, 
immersed in the substance of the frond, and scattered through its upper 
segments, each with a pale margin, and filled with very numerous spores. 
2, roundish or irregularly shaped warts (nemathecia), sessile on the frond, 
and densely scattered over its surface, wholly composed of vertical, 
dichotomous, moniliform filaments. Swéstance cartilaginous and firm, 
rather thin. Colour a deep, but dull, blood-red, paler, and more pinky in 
the younger parts. In drying, it does not adhere to paper. 
RAPA PIE ~ 
The first account of this species is given by Bishop Gunner 
in his Flora Norvegica, if, indeed, the synonym of that author be 
correctly referred by Turner to this place ; a fact which has been 
more than once suspected, many believing that the plant repre- 
sented by Gunner is only a variety of C. crispus. Mr. Dillwyn 
was the first to detect it on the British shores, as well as the first 
to notice the nemathecia-fructification, which is the only kind 
described by Turner, and is much more generally produced than 
the tubercles ; indeed, it is very rare to find a plant destitute of 
nemathecia. The ¢vdercles have, I believe, only been found by 
Mrs. Griffiths at Torquay, and by her but seldom. They are at 
once distinguished from the nemathecia by their more regular 
form, and the colourless limb which surrounds them; and by 
being evidently immersed in the substance of the frond. 
Chondrus Norvegicus, if it be identical with the northern plant 
described by Gunner, is singularly unfortunate in its specific 
name, as it is much more common to the south of Norway than 
in that country. Even in England, it is very much more abundant 
on the south coast, and occurs still more frequently on the shores 
of France and Spain, and in the Mediterranean. Though with a 
general resemblance to C. crispus, there is something in the tone 
of its colour, the divaricated lacinize, and the rounded axils and 
apices that render it easy to be recognised, independently of the 
difference in fructification.. The species most nearly allied to it 
is C. crenulatus, a native of Portugal, which may probably yet be 
added to the British list.
