 broad- and narrow-leaved varieties are common. A few 

 stunted plants were noticed on Macaulay Island. New 

 Zealand.

 rhomboid, 3-5-lobed, acute or acuminate, tomentose when 

 young, almost glabrous when fully grown ; petioles 3-9 

 inches long. Panicles large, terminal, much branched. 

 Flowers monoecious, not seen in a perfect condition, the 

 calyx and corolla having just fallen before the time of our 

 visit. Fruit almost 2 inches in diameter, usually with 2-3 

 cocci. Seeds globose, rugose, hard, and bony. North 

 and east side of Sunday Island ; not very common. North 

 Australia, Polynesia, and the tropics of both hemispheres.

Sunday Island ; not uncommon in sheltered places. 

 Macaulay Island ; half-a-dozen plants in the old crater 

 basin. A graceful tree, with very handsome glaucous 

 foliage, variable in shape and size. The leaves of young 

 plants are often more than a foot in diameter ; but they are 

 seldom half that size in fullv grown individuals. Endemic.
