13, After all there are still several plants remaining unclassified, as 
to geographical distribution—Aabitat or altitude—not a few of which 
are among’ the most noble and useful of all our vegetable productions. 
These have hitherto not been classed as to area or zone, from their being 
more or less ubiquitous. The principal of them will therefore have now 
to be briefly considered in three seperate divisions, viz. (i.) Plants 
common to the whole North Island ;—(ii.) Plants (unenumerated as to 
area or zone) not found in the South parts of the Island ;—and, (iii.) 
Plants (also unenumerated as to area or zone) not found in the North 
parts of the Island.— 
Ci.) Plants common to the whole North Island.—among these the 
following may be noticed :—Cardamine hirsuta, in all soils and situations, 
to the alt. of 2500 feet. leocarpus dentatus; Aristotelia racemosa ; 
Alectryon excelsum ; Dodonea viscosa; Pelargonium clandestinum, from 
the sea coast to 2000 feet; Oxalis corniculata, in all soils from the sea 
to 2000 feet ; O. Magellanica, from 500 to 5000 feet ; Hdwardsia grandi- 
Jlora, in all soils form the sea to 2500 feet; Coriaria ruscifolia, in all 
soils (but not iz woods) from the sea to 3000 feet ; Rubus australis, in 
all soils from the sea to 2500 feet ; Acena Sanguisorbe, in all soils from
