Although the above figures show the relative importance of the larger- 
 families and genera, so far as the flora is concerned, they exaggerate the part 
that some play in the vegetation. In this regard many small genera are of more 
moment although they may be of restricted distribution ; the following to which 
the number of species are appended are examples: — Oyatlea 5, Hemiteha ı, 
Dicksonia 3, Pteridium ı, Gleichenia 6 (Filices); Agathis ı, Libocedrus 2 (Pinac.); 
Typha ı (Typhac.); Freycinetia ı (Pandanac.); Arundo 2 (Gramin.); Mariscus ı, 
Schoenus 7; Gahnia 8 (Cyperac.); Rhopalostylis 2 (Palmae); Zeptocarpus ı, Hy- 
polaena ı (Restionac.); Rhipogonum ı, Cordyline 4, Astelia 9, Phormium 2, 
: Chrysobactron 3 (Liliac;.) Nothofagus 6 (Fagac.); Zlatostema ı (Urticac.); Ziy- 
franthe 4 (Loranthac.); Muehlenbeckia 5 (Polygonac.), Carpodetus ı (Saxifrag- 
ac.); Weinmannia 2 (Cunoniac.); Rubus 7 (Rosac.); Sophora 4 (Legumin.); Co- 
riaria 4 (Coriariac.); Pomaderris 4, Discaria ı (Rhamnac.); Aristotelia 3 (Elaeo- 
carp.); Plagianthus 3, Hoheria 3, Gaya 2 (Malvac.); Melicytus 4 (Violac.); Zepto- 
. spermum 4, Myrtus 4 (Myrtac.); Fuchsia 3 (Onagrac.); Nothopanax 7, Pseudo- 
 Panax 7, Schefflera ı (Araliac.); Griselinia 2 (Cornac.): Gaultheria 6 (Ericac.); 
Siyphelia 8, Epacris 2 (Epacridac.); Rapanea 3, Suttonia 5 (Myrsinac.); Olea 4

EARR In contradistinction to the above, the following genera are so rare that 
their absence from the vegetation would not be noticed: — Simplicia ı, Am- 
.. Phäbromus ı (Gramin.); Hydatella ı (Centrolepidac.); Iphigenia ı (Liliac.); Ba- 
grisia ı (Burmanniac.); Calcana ı (Orchidac.); Phrygilanthus 2 (Loranthac.); 
 Myosurus ı (Ranunculac.); ZLogania ı (Loganiac.); Cuscuta ı (Convolvulac. 
and Tetrachondra ı (Labiatae). ee ee. 
_ A considerable number of genera, Perhaps more than 25 P. c., are ı 
 Itary under considerable changes of environment.
