Apparently a native of Kerguelen’s Land only, where it was found sparingly, adhering to the stems of largei-

One of the most beautiful of the genus, and probably the southern representative of the European N.punctatmn,
ehieily distinguishable from it by the long cuneate base of the frond passing into a filiform stem and by the absence
of diohoiomous divisions with wide axUs. The traces of the stem become gradually more faint at a short distance
from the base of the frond, but do not break up into numerous veins. The normal form of the frond is broadly
lanceolate, tapering to an acute poiut ; with waved but entire margins, which are, however, often split and torn into
numerous linear ribbon-like segments, caused by injury and not the natural divisions of the frond.

Of this plant we have not ver}» satisfactory specimeus, or whieh may not belong to the Delesseria dichotoma ;
except that in the present species the nerves are much fainter, less distinct fi-om the lamina, and vanishing further
from the apex of the frond, which evinces no tendency to form distmct leaves.

This is a very distinct species ; but, like its congeners, so variable in form that httle dependence can be placed on
the characters drawn from its outline, or from tlic length of the stipes. Our figure gives a very faithful representation
of the colour and normal form of the old and young states, both veined and nearly veinless.
