FROM THE FALKLAND ISLANDS, 185 
is probable that under certain conditions or in certain stages of growth the 
fronds of other species possess a similar outline. The cystocarps being 
situated on the nerves, and the tetraspores in sporangial plants in lines on 
either side, locate it as a Pteridium, where it is fairly distinct from other 
species. From Pteridium proliferum, A. & E. S. Gepp, which was collected 
at the Orkneys by the ‘ Scotia,’ it differs in the broader segments and dispo- 
sition of the tetraspores. 
The species is named after the late Mr. W. Wickham Bertrand, Mrs. Val- 
lentin’s father, who took the greatest interest in the flora of the islands, 
and especially in the present collection of Cryptogams.

Formerly thought to extend to Australia, but the specimeas from that 
continent were shown by Agardh to be a distinct species (.D. simulans).

It is possible that more than one species is at present included under this 
name, as there are a few specimens both in the Hooker and Vallentin col- 
lections which have fronds markedly broader and of a deeper colour than the 
ordinary form.

Disrris. Fuegia! Falkland Islands (?). 
There are four of Hooker’s specimens at Kew, three precisely similar from 
Cape Horn agreeing with the figure in ‘Flora Antarctica,’ and a fourth, 
apparently different, from Berkeley Sound. Its claim to occur in the Falk- 
lands is therefore doubtful. Dickie’s Kerguelen record is certainly incorrect,
