The difference between this and the following species is not clear. The 
Falkland Islands Callithamnieæ are as yet very imperfectly known, and 
several undescribed species probably exist. Three or four plants collected 
by Mrs. Vallentin, also some unnamed specimens in the Kew Herbarium, are 
referable to Callithamnion or an allied genus, but being sterile cannot be 
determined.
