Coming now to some of the rarer coastal trees, — Pittosporum Huttonianum

This association occurs at various places from Wellington to Cheviot in 
the South Island, but, in proceeding S., its species greatly decrease. Coryno- 
‘ carpus has already been cited as an important member of northern coastal- 
forest, but it and its associates have been considered at best a sub-association. 
A typical example, such as occurs on the Wellington coast, or Kapiti 
Island, has a somewhat billowy, close roof, the different’ greens of which denöte 
certain species as, — dark-green, Corynocarpus; pale yellowish-green, Melicytus. 
ramiflorus;, bright pale-green, Myoporum; darkish-grey, Leptospermum scoparium, 
An outer girdle faces the shore, composed of: — Macropiper, Paratropns 
opaca, Urtica ferox, Hedycarya arborea, Corynocarpus, Melicytus vamıiflorus, 
Pseudopanax crassifolium, Myoporum, Coprosma' Baueri, and of these the two 
last and the Urtica are nearest the shore. A little further from the sea, oth 
trees are present, especially: — Rhopalostylis sapida, Knightia, Pittosporum 
tenuifolium, Melicope ternata, Dysoxylum spectabile, Pennantia, Fuchsia excorti- 
cata, Nothopanax arboreum, Coprosma grandifolia, Brochyglöimis repanda a 
Oltarda Cunninghamii. The principal lianes are Blechnum filiforme and Freyer- 
netia (both important floor-plants also). Frequently, the interior of the forest 
is open. Ferns are common, e: g. — Adiantum affine, A. fulvum, species of 
Pteris, Dryopteris velutina, Polystichum Richardii and Asplenium Hookerianum. 
In the South Island d Corynocarpus extends to Banks Peninsula and 1
