 gellanic Expedition will appear next year. He has taken the tronble to send me all 

 the identifications necessary for the description of the plant-associations. The he- 

 patics of botli expeditions were described by Mr. Stephani. Dr. O. V. Darbishire 

 has just published the report on the Antarctic lichens, and his identifications of the 

 specimens I collected in the Falklands have been made use of for this paper. The 

 material collected during the present expedition was placed in the hands of Dr. Th. 

 Fries jun. in Upsala who has communicated to me the names of certain important 

 species.
