PLANTS OF THE OUTLYING ISLANDS.

The commonest of the forest-trees is the karaka, here called kopi 

 rt/Hocarpus laevigata), whose smooth bark was frequently adorned 

 with a figure of a three-fingered man by the Moriori artists (fig. 56). 

 Then come the matipo (Suttoniachathamica), the mahoe (Hymenanthera 

 chathamica], an indigenous daisy-tree (Olearia Traversii. akeake), 

 the tree-karamu (Coprosma chathamica) , the lancewood (Pseudopanax 

 ch/tthamica), the ribbon wood (Plagianthus chathamicus), the nikau 

 (Rkopalostylis sapida). There are two distinct classes of forests on 

 the island, that on the higher ground containing fewer species, and, 

 having the large heath, Dracophyllum arboreum, as its dominant tree.

The forest on the limestone formation near the great lagoon, the 

 Whanga, is also somewhat different, since there alone is the kowhui 

 to be found. 



There is no shrubby undergrowth in the forest, but tree-ferns and 

 ferns of all kinds are very abundant. The only lianes are the supple- 

 jack, the climbing-convolvulus (Calysteyia tuguriorum), and Muehlen- 

 beckia australis. Many most characteristic New Zealand forest-trees
