brane; 1, spherical ¢wbercles, borne on little stalks, mostly along one side 
of the mid-rib, containing a profusion of ovate spores; 2, obovate sporo- 
phylla, densely clothing the mid-rib, and thickly covered with a stratum of 
minute tetraspores. Substance of the leaves delicately membranous, their 
surface glossy and shining. Colowr a fine crimson pink. It adheres to 
paper in drying.

This fine plant, whether we regard the splendour of its colour 
or the elegance of its form, is entitled to high rank in the 
Oceanic Flora, and notwithstanding its common occurrence on 
all our shores, is never seen without attracting admiration. 
In favourable localities it reaches to a very large size, the length 
and breadth of its leaves greatly exceeding what our plate repre- 
sents, and such specimens are among the most beautiful vegetable 
objects in nature. It therefore worthily commemorates, as the 
type of the genus to which it belongs, the services rendered. to 
Botany by one of her most distinguished votaries, whose recent 
loss will long be severely felt, and whose place m the wide circle 
of which he was the centre, can never be supplied. 
The variety with /oded leaves, mentioned in the description, 
was sent to me by the Rev. D. Landsborough, who gathered it 
on the coast of Ayrshire. It is a very curious form, showing a 
tendency towards D. sinuwosa, from which, m colour and other 
respects, it widely differs. It has also a considerable hkeness 
to D. Davisti, a plant of the Southern Hemisphere, but im that 
species the lateral nerves are alternate, not opposite; a character 
which appears to be constant. Another variety, which I have 
from the Baltic, has exceedingly narrow, lanceolate leaves, and, 
until closely examined, might pass for a form of D. Hypoglossum. 
T have seen no British specimens hke it. 
Dr. Hooker found at Cape Horn, two states of this species, 
one resembling our British plant, except that each leaf was eigh- 
teen inches in length! and proportionably broad ; the other with 
lanceolate leaves, from whose mid-ribs innumerable minute leaflets 
spring. This last was only found in a young state, and may 
possibly belong to a distinct species, which should be called 
D. Hooker.
