Anatomy of leaf of specimen from forest, Transit Hill : Upper epi- 

 dermis of single row of thick-walled cells with thick cuticle. Palisade 

 tissue a single row of cells about 1^ times as long as the thickness of the 

 epidermis, densely packed with chloroplasts. Spongy tissue of irregular 

 cells with many air-spaces. Lower epidermis similar to upper, the cuticle 

 equally as thick. (See fig. 1, c.) 



Habitat : Common from sea-level to 400 m. alt. A shrub in coastal 

 scrub and on ridge at top of sea-cliffs, Northern Hills ; a large tree in forest. 



Distribution : Australia.

 Ann. Bot. x, 251, 1896. 



Anatomy of leaf of specimen from Northern Hills : Upper epidermis 

 with thick cuticle, one layer of cells with thick walls. Palisade tissue of 

 two or three rows, the first of long, the second and third of shorter, cells ; 

 chloroplasts dense. Spongy tissue occupies about two-thirds of the meso- 

 phyll ; small cells with a few air-spaces. Lower epidermis similar to upper. 

 Vascular bundles with large sheath of sclerenchymatous tissue, little wider 

 than the bundle above it, but much wider below it. (See fig. 2, b.) 



Habitat : A shrub in lowland forest, in coastal scrub, and scrub on 

 ridge at top of cliffs, north coast. 



Distribution : Norfolk Island, Australia, New Caledonia.
