Mr George M. Thomson (jn the 



and Hypericum japordcum shows a tendency in the same 

 direction. Distinct heterostylism has not yet been pointed 

 out. A form of it occurs in various species of Pimelea 

 (and apparently in one or two other plants) ; but in this 

 case appears to me to be a step towards dioocism (to coin 

 a new word). 



In conclusion, I would point out that it is remarkable to 

 what a degree the separation of the sexual functions in the 

 New Zealand Phanerogams is carried out. A reference to 

 the appended table will show this as occurring in Clematis 

 (among Ranunculacese), Plagianthus (Malvaceae), Fuchsia 

 (Onagracese), and Leptospermum (Myrtacese), all orders 

 characterised as a rule by hermaphrodite flowers. In 

 some genera as Fuchsia and Pimelea, &c., I believe we can 

 see the changes towards absolute separation now going on.

Uxplanation. — Under the lieading Compicuous Flowers, 1 stands for very large 

 blossoms 2 inches in diameter (or length), 2 for flowers about an inch, and 3 for 

 Howers of ^ inch or thereabouts. The same numbers are employed for those 

 blossoms which are conspicuous by association, and sometimes a flower is marked 

 as occurring in both columns, when the blossoms are individually large, and are 

 also associated into prominent masses. Proterandrous hermaphrodite flowers 

 = p.a - proterogynous = p.g.
