A rare and little-known plant. The species is based on Hooker’s Falkland 
Islands specimens, and has not been found since. Two doubtful gatherings 
from Kerguelen exist at Kew, one of which is named and recorded by 
Hooker, but the plant differs considerably from the type, and is, indeed, 
marked by him with a query. 
De Toni (Syil. Alg. iv. p. 257) has cast doubt on the generic position of 
the species. А photograph of one of the two original specimens at Kew is 
reproduced on Plate 7 ; the other specimen, from St. Salvador Вау, is less 
elongated and has broader fronds. From the form and structure of these 
specimens the plant appears to be a genuine Phyllophora, though, as both 
are sterile, it is impossible to speak with certainty. "The specimens collected 
at West Point Island, referred with some doubt to this species, are also 
sterile.
