176 MR. А. D. COTTON ON CRYPTOGAMS 
C. variolosum, belong rather to C. fastigiatum, and the same applies to the 
Kerguelen specimens. The exception (a Hooker specimen from Magellan) is 
intermediate in form and would appear to be composed of loose tissue in the 
young fronds, which becomes dense and compact later. Hohenacker’s 
Dumontia fastigiata, var. minor, Exsice. 282, from the East Falklands, is, in 
the British Museum set, a small specimen only, but clearly not referable 
either to Dumontia or Chetangium.

This plant is probably more widely distributed than generally supposed. 
Specimens were recently received at Kew from Queensland, the first record 
for the continent of Australia.

The only evidence of this plant having been found in the Falkland Islands 
is Gaudichaud’s specimen in the Paris Museum. Нагіоё (1. с. p. 62) was 
inclined to believe that the locality might have been incorrect ; but, as Gain 
states that a plant indistinguishable from this species is plentiful in the islands 
off Graham Land, it is possible that it extends also to higher latitudes.

I have followed Gain, who unites J. micans with J. cordata. Hooker and 
Harvey held this view, though subsequently treated them as distinct. Gain 
gives a useful history of the plant, together with a full list of synonyms. 
From his account one would be almost justified in assuming that all the 
so-called species of the genus from South America and the Subantarctic are 
merely forms of the exceedingly variable Z. cordata.
