A few barren stems of a species to all appearance not different 
from R. bifarium (Hook. Muse. Exot. t. 57, Hypnum) were picked 
from some Mosses which came from Herb. R. Brown, and were 
supposed to have been collected in Jamaica; but, as nothing 
further can be ascertained respecting them, the species, if it 
really occurs in the West Indies, must be left to future explorers.
