British New Guinea: Mount Scratchley, 10,000-13,000 ft, and 



Wharton Range, 11,100 ft., Giul ianetti. 



This is one of a number of interesting plants collected by INI r. A. 

 Giulianetti in the mountains of British New Guinea, and presented to 

 Kew by Sir William MacGregor. A full account of these plants will 

 shortly appear in the Kew Bulletin. The genus Oreamyrrh is is common 

 to the Andes, New Zealand, and Australia, and this is apparently the 

 lirst species found in New Guinea. In foliage it differs entirely from 

 all the previously known species, whilst in other characters it is quite 

 normal. The foliar organs are apparently flattened petioles terminating 

 in a minute rudimentary blade. — W. Botting HEMSLEY.
