48 PLANTS FROM NEW CALEDONIA. 
of the neighbouring islands. For example, the interesting primitive lichen 
described by Schmidle from the Samoa Islands as Scytonema Hieronymi 
occurred in well-developed masses on tree-trunks in New Caledonia. Another 
lichenised alga, Trentepohlia dialepta, originally described from New Guinea, 
also occurs in New Caledonia. The discovery of Closterium compactum, 
described by Nordstedt from New Zealand, was also of interest. Further, 
the investigation has added considerably to our knowledge of the distribution 
of various algee, since many species only hitherto known from localities very 
remote from New Caledonia occurred in the collections.
