Distris. South Orkneys, Falkland Islands. 
The present is the first record of Monostroma for the Falklands, and it is 
a genus apparently rare in subantarctic regions. M. endiviwfolia, though 
previously only known from the original locality, has probably in the past 
been mistaken for young plants of Ulva. А specimen of Hooker’s inscribed 
“С. rigida?” exists at Kew, and this shows a distinct Monostroma structure 
and almost certainly belongs to the present species. Miss Hennis's speci- 
men is larger and more laciniate tham previous gatherings.

Each of the three varieties, or forms, genuina, Hauck, rigida, Le Jolis, 
and latissima, Ardiss., appear to be present, the last-named being, according 
to Hooker, abundant in land-locked lagoons.

DISTRIB. Cosmopolitan. 
Hooker included the following species, which is hardly distinct, under 
this name, hence C. compressa, though doubtless common, is perhaps not 
quite so abundant as he supposed.

Hooker's specimens have not been found in the Kew Herbarium. Mrs. 
Vallentin collected several plants, which are apparently referable to this 
species, but they approach very closely to the flattened tapering forms of 
E. intestinalis.

Kiitzing detected this form amongst Hooker’s Berkeley Sound specimens, 
and named it А. Hookeri ; later it was shown to be a synonym of Suhr's 
Solenia bulbosa.
