to use the common but more incorrect term. Yet in the Auckland 
Rotanical Districts the shrub passes through a distinct juvenile form 
with leaves much broader than those of the adult (see text-figure

south both juvenile and adult have the narrow leaves (compare the 
juvenile forms in the two text-figures), but exactly where the line of 
separation comes between the two varieties has not been ascertained. 
One more example of the distribution of true-breeding races of 
an aggregate species and the chapter must end, though there are

many matters connected with distribution in New Zealand that 
have been left unsaid. This is the case of the aggregate Celmisia 
glandulosa, frequently a plant of subalpine bogs or wet herb-field. 
Generally speaking, throughout the area of its distribution it is 
represented by a well-marked variety (the “type”); but on Mount 
Egmont this variety is absent, and in its stead a plant with much

(Fiord Botanical District), it is neither of the above varieties which
