 inches long, scarred below, much branched and bushy at top ; 

 branchlets small and slender, close, bark black. Leaves very

Hah. Base of Mount Ruapehu, County of East Taupo ; 

 " altitude 5,400 feet ;" 1887 : Mr. H. Hill. 



Obs. I have received several specimens of this plant, but all 

 past flowering. It does not appear to be closely allied to any of 

 our New Zealand (and South Pacific) species ; perhaps it 

 approaches more nearly in a general way to P. simplex, Forst., 

 and to P. sindairii, Hook. f. 



Order XXXVIIL— RUBIACE^.

 distant in whorls of 4 on the main stem (sometimes 3, and on 

 ultimate branches only 2, and very small), linear-lanceolate,
