MuEHLENBECKiA AXILLARIS, Walj). — Climbs up trees for 20 or 

 30 feet. Sometimes called " Bed Vine," as the islanders say it is

Piper excelsum, Forst. — Worthy of cultivation by reason of 

 its large, broad, handsome glabrous leaves, up to 9 inches in 

 diameter, and showy red spikes of flowers. Known as " Kava " 

 on the island, an additional instance of the use of tropical South 

 Sea island names for plants supposed by the islanders to be 

 identical with their tropical namesakes. 



LAUKINE5:. 



Cryptocarya triplinervis, R.Br. — " Blackbutt " is the name 

 by which this tree is known on the island, but it must not be 

 confused with the Blackbutt of the mainland ( Eiicalyftus pihi- 

 laris). It is found all over the island, and is esteemed a good 

 all round timber. It is one of the best firewoods on the island, 

 burning green. It attains up to 5 and 6 feet in diameter. It is 

 an exception to the general run of Lord Howe timbers, which are 

 usually surface-rooters. " Blackbutt " is accounted to be the 

 most difficult tree to stump (root out) in the island. 



SANTALACE^. 



ExoCARPUS HOMOCLADA, F.v.M. — Known as "Grass-tree." See
