This plant forms part of by far the most interesting portion of 

 the botanical collections made during the ' Challenger ' Expedition 

 — the portion obtained in the Indian Archipelago, North Australia, 

 and the Admiralty Islands. The flora of the latter islands being 

 enthely unknown, I greatly regret that I did not pursue my 

 original intention of preparing a memoh in extenso upon it. I may 

 state here that the Admiralty Islands have a well-marked Malayan- 

 flora ; so that G-risebach's a priori conclusion (see map in ' Vege- 

 tation der Erde ') is amply sustamed.
