doubtful synonym of his species D. lancifolia from the same locality. This 
has generally been assumed to be correct, and the Hooker specimens at Kew 
are found to agree fairly well with Agardh’s description. The single and 
very fine specimen collected by Mrs. Vallentin is useful in providing the 
hitherto-unknown cystocarps. These are borne in minute proliferations, 
which arise over the entire surface of the frond. The cystocarps occur 
singly or in twos in the proliferations. 
D. lancifolia, var. minor, Laing (Trans. N.Z. Instit. xxix. p. 450), from 
Macquarie, is probably a distinct species.

D. crassinervia covered a number of species. The true plant, known only 
with certainty from New Zealand, Campbell and Auckland Islands, appears 
to be a Hypoglossum, and 1). Montagneana, which was separated from it, has 
been shown by Laing also to be a composite species. P. epiglossum is, so far 
as known, confined to the Cape Horn district.

The present species is apparently frequent in Kerguelen, and it occurs also 
in the Magellan district. In the tetrasporic state it is very well marked, but 
in the sterile or even cystocarp condition it is not always easy to identify with 
certainty. For this reason the Falkland Island record has had to be marked 
with a query ; but, as the plant occurs at Port Famine, there is no danger of 
a geographical error. Abundant material from Kerguelen exists in herbaria, 
and, being hitherto undescribed, it was advisable to deal with the plant even 
though its discovery on the Falklands themselves had not been positively 
certified. The type-material is that collected by Eaton during the ‘ Transit 
of Venus’ Expedition (see Plate 8). 
The cuneate segments give the plant a very marked appearance, though it
