THE MOSSES OF DUTCH NEW GUINEA. 



Jescribi'd us " st.ricte revoluto," wliile in the New Guinea plant the margin is thickened,. 

 but in such a way tliat it may eadly appear as revoliite. On account of these characters 

 I hftve retained the New Guinea niuss as a separate Fpecies, hut with a stron? suspicion 

 that the dilTerences are only clue to ditTeient interpretations of the observed facts, and 

 that our plant may be found to be conspecific with tlie Ceram nioss, 



Ileiztig (op. eit, Ixi. 293) has an interesting note on tlic remarkable airmity of the 

 mosp-flora of the Ishiiuls Burn and Ceraui with that of New (Uiinea; an ailinity which 

 will bo still more emphasised if, as I strcmgly suspect, his Ihjpnvikndron macrocarjmni 

 (op. cit. Ivii. 241) is identical with the New Guiuea //. aitrkomnm Broth, ifc Geh. It 

 is probable also that my ThukUum scahvibnicteatum (aute, p. 1^9) may be identical with 

 T. himantophyUim IIerz.~TI. N. B., Feb. 1922.
