FROM THE FALKLAND ISLANDS. 183 
The plant recorded as D. platycarpa in ‘ Flora Antarctica’ is certainly not 
the same as D. platycarpa, Lamour. (= Botryoglossum platycarpum, Kütz.), 
from the Cape. It is apparently a rare or local species, as it has not been 
obtained since Hooker's time, but his record remains. The original specimens 
have tetraspores in the main fronds as in Nitophyllum, and not in special 
leaflets as in Botryoglossum, and correspond fairly closely with Bory’s figure 
of №. Durvillei (28, tab. 19). This alga was collected at Concepcion, Chile, 
and is little known ; hence, though the Falkland Island plant is closely allied 
to it, it appears best not to link it too definitely with that species till further 
data on the distribution and variation are available. It is therefore listed 
with a query.

J. Agardh, during the last years of his life, transferred this well-marked 
and very fine species, together with two others, toa separate genus, Platyclinia, 
the necessity of which was open to question. In addition to its laminate 
frond, P. Crozieri may be distinguished from other Falkland Islands Nito- 
phylleæ by the tendency of the cells to be collected together into groups of 
2 ог 4 аз in Porphyra.

The nomenclature of the Delesserieæ is much complicated, owing to the 
liberal views as to species held by the older writers and by the poorness of 
much of the original material. D. phyllophora was one of the species 
separated from D. crassinervia, Hook. f. & Harv. (non Mont.), by J. Agardh. 
Tt was founded on a Falkland Island specimen collected by Hooker in 
1842, and two or three plants apparently referable to it exist at Kew. The 
Kerguelen plant recorded by Hooker and Harvey is probably distinct from 
D. phyllophora, which, so far as I can judge, has not been met with else- 
where nor since that date.

Tt is with some hesitation that this species is added to the Falkland Islands 
list. Agardh quoted P. sanguinea, var. lancifolia, Hook. f. et Harv., as a
