The portion of New Zealand treated of in this section varies considerably 
in altitude in proceeding from N.to S. In the Northern botanical province, 
with the exception of one or two summits of the Thames Mountains, all the 
hills, even when they considerably exceed 600 m altitude, bear a vegetation 
of a lowland stamp and true alpine plants are wanting. Allthe same, certain 
species ascend far higher than others and there are more or less distinet s 
altitudinal belts.. In the Central province, especially in the N., high-mountain 
species do not generally appear until an altitude of at least Ho6 m is reached. 
In the Southern Province, though 600 m may be taken as the upper average 
limit of the lowland-lower mountain belt, no universal delimiting line can be
