figure we were well acquainted with what is now called 
M. Jaubertiana, but which we had unhesitatingly referred 
to Turner’s Fucus abscissus. Nothing at all more resembling 
Turner’s figure is known to us. Some of our specimens 
indeed might well pass for that he has depicted; while 
others resemble closely the larger form figured by the French 
Algologist. The difference mainly insisted on by M. Mon- 
tagne lies in the stem, which in M. Jaubertiana is cylin- 
drical, in Fucus abscissus * flat without veins or midrib.” 
Were the M. Jaubertiana cylindrical throughout, we should 
not hesitate to agree with Montagne. But it is not 
so. The frond is most cylindrical below, it gradually dimi- 
nishes upwards, and the upper portion is perfectly flat. 
The larger the specimen, the rounder is the stem, and in 
young specimens we find the frond compressed even in its 
lowest part, and if Turner’s figure be taken to represent a 
young specimen, it is a characteristic. And it should be 
observed, that though he describes the frond as flat, the 
figure of a transverse section which he gives evidently re- 
presents a compressed frond.

A beautiful plant, generally recognisable by the broad, flat, 
more or less midribbed frond and shining surface ; but varieties - 
occur which approach the var. sesquipedale of G. corneum. We, 
have ascertained our plant to be the same as that of Turner, 
having been favoured by Mr. Brown with an inspection of 
his original specimen.
