Rubiaceae 27; Cyperaceae and Orchidaceae 22; Taxaceae and Myrtaceae 16; 
Compositae 14: Liliaceae ıı and Araliceae ı0. The most important genera 
and the number of their species are as follows: — Coprosma 24; Hymenophyl- 
lum 16; Blechnum, Pittosporum and Metrosideros 9, Carex 8 and Trichomanes, 
Asplenium, P are: Gahnia Corysanthes and Uncinia 7. Leaving the pterido- 
phytes on one side, 89 per cent of the spermophytes are endemic, while the 
greater part of the remainder are Australian. The following genera, all but 
3 being monotypic, are endemic and confined to forest: — 7upeia, Dactylanthus, 
/xerba, Carpodetus, Alectryon, Hoheria, Tetrapathaea, Corokia, Teucridium, 
Kalbe Alseuosmia and Colensoa. Other endemic genera, but which 
occur in other formations, are: — Lorsoma, Suttonia and Brachyglottis. 
The growth-forms of lowland-forest are: — Trees 09, shrubs 63, herbs‘sı, 
grass-like plants 26, ferns 88, lianes (excluding ferns) 26, epiphytes (excluding 
ferns) ı5 and parasites ı3. The ferns include 8 tree-ferns, 23 filmy ferns, 
7 lianes and ı7 epiphytes. 
So far as physiognomy is-concerned, there is a considerable resemblance 
between the various rain-forest associations throughout the range of the for- 
mation, but one rather ecological than floristic. This likeness is owing to the 
following circumstances: — ı. The presence of taxads with one or other of 
their species frequentiy dominating. 2. The great abundance of tree-ferns. 
3. The vast number of ground-ferns (Fig. 28) many of which are of wide 
distribution, and the presence throughout in quantity of Asplenium bulbiferum, 
Blechnum capense and B. discolor. 4. The presence in abundance of the 
lianes Muehlenbeckia australis, Rhipogonum scandens, Metrosideros hypericı- 
Folia and Rubus australis. 5. The density of the undergrowth and
