stigma. The flowers are perfectly symmetrical in the number 
of their parts. 
Now look for the small-flowered kind. You will find that 
the structure is very similar to that of the large form, with 
one important exception—namely, that the anther-cells con- 
tain no pollen. So, while both kinds are ¥ in structure, the 
smaller form is only @ in function.

small kinds. (ca, calyx; pe, petals.) 
It is worth while to watch a tui or honey-bird (korimako) 
when busy among the fuchsia-flowers, and you will see how 
they are fertilised. You will also understand why the flowers 
are pendulous, why the filaments and style are so long and 
the pollen so much tied together, and why there is such a 
large quantity of nectar produced at the base of the long tube. 
By closely watching you may easily see that the feathers 
immediately above the bird’s bill are smeared over with the 
blue pollen. . 
The fruit, which ripens from January to March, is a berry 
—i.e., a fruit in which all the layers of the pericarp have 
become succulent. The object is evidently the same as that 
aimed at in the structure of the fruit of the bramble, rose, 
strawberry, &c.—namely, that birds may be tempted to 
swallow them, and thus distribute the seed. 
(a.) Compare with these flowers those of garden or green 
house fuchsias, which are hybrids of South American spectes- 
They differ chiefly in the much brighter colours of the calyx 
and the greater development of the petals, which are Col 
volute in arrangement. Also try to get hold of the pretty
