Campbell's Islands.'] FLORA ANTARCTICA. 19 



islands beyond it. As far as I am aware, it had been previously gathered by Forster alone. In this group it 

 attains a height of 30 feet, amongst other trees near the sea. Its trunks are sometimes 2-3 feet in diameter, 

 covered with a smooth brown bark ; the wood is white and close-grained. Branches much scarred, and clothed 

 with a pale bark, very brittle. The distinct joint at the apex of the petiole indicates the truly compound nature 

 of the leaves ; they are nowhere described as ternate ; a character which all young trees of this species exhibit. 

 The whole plant has a faint but rank smell, like that of Ivy, which the copious lurid green but shining coria- 

 ceous leaves much resemble, both in hue and texture. The involucral leaves are very small and subulate.
