3. Changes in species according to latitude. 
The coast-line, from the Three Kings’ Islands in the N. to the southernmost 
part of Stewart Island in the S., extends through 13° of latitude from about 
34° 20’ S. to 47° 20’ S., or if comparisons be drawn from the northern hemi- 
sphere, from the mouth of the Loire, in France, to Rabat on the W. coast 
of Morocco, or from the N. of the E. coast of New Brunswick, in North 
America, to ie extreme S. of North Carolina. Since, in coastal Alant-distributio®, 
variation in altitude does not come into consideration, the effect of change in 
latitude is more clearly reflected in the distribution of the coastal element 
coastal distribution which follow may be noted in this respect. 
he Northern, Central and Southern botanical provinces contain respect- 
ively 120, ıı8 and 120 coastal species with 29, ı4 and 4ı species peculiar to 
each. Only 4 of the special northern species occur throughout the province, 
leaving the Three Kings botanical district”) out of eonsideration, while, as for 
the remainder, 6 species are confined to the Three Kings; 3 occur Sa on 
the North Cape Promontory; 7 do not extend beyond about lat. 35° 30’ S., 
and, of these latter, 4 have been recorded each from one’locality only, 7 do 
not occur 5. of Manakau Harbour, but none of these are wide-spread while 
3 are of most restricted distribution; finally 2 are confined to the Thames 
sub-district. = 
All the species peculiar to the Central province are either of local or 
most restricted distribution and none occur in the Egmont-Wanganui district.
