so that the alpine flora, as a whole, numbers 945 species as against 958 for 
the lowlands and lower hills while if the alpine and coastal elements be deducted 
from the latter the alpine flora exceeds the lowland by 80 species. 
If the 99 occasional lowland species be considered as virtually alpine, the 
high-mountain element of the New Zealand flora will number 597 species be- 
longing to 45 families and ı23 genera. No less than 561 of the above species 
(94 p. c.) are endemic, and, if only the dicotyledons be considered, the percentage 
rises to 97. The affınities of the remaining species are: — Australian 22, 
Fuegian 9 and cosmopolitan, or nearly so, 6. The above does not do justice 
to the Fuegian relationship, since about 35 species, belonging to 35 genera, 
have near relations in subantarctic South America’). 
The following ı5 genera (7 endemic) and one family are confined’) to the 
high mountain belt: — Marsippospermum, Exocarpus, Hectorella®°), Pachycladon®, 
Notothlaspi°, Corallospartium®, Swainsona, Pernettya, Loganiaccae (Logania, 
Mitrasacme), Phyllachne, Forstera, Leucogenes,°) Haastia® and Traversia®. This 
does not show anything like the local endemism of the lowland flora with its 
ı5 locally endemic families and 94 genera, but the following two lists bring 
out more clearly the striking floristic differences between the two floras, and, 
at the same time, with what ‚has gone before, show the special composition 
of the high-mountain flora. 
. Genera typically alpine which descend to sea-level, or thereabouts, 
only Ad special circumstances: — Alsophila, Cystopteris, Triodia, Carpha, 
‚Oreobolus, Lyperanthus, Adenochilus, Caltha, Drapetes, Schizeilema, Archirta, 
Ourisia, and Adrotanella.
