Postscript (July 3rd, 1894) : — The quite recent addition to the 

 Society's library of some of the earlier volumes of the Proceedings 

 and Transactions of the New Zealand Institute — wanting since 

 the destruction of the library in 1882 — has enabled Mr. J, J. 

 Fletcher to call my attention to an important paper* by Mr. 

 Cheeseman, on the fertilisation of Selliera, of which I was pre- 

 viously unaware, and which I regret that I was unable to refer to 

 in the proper place. The author's observations (made in 1876) 

 agree with mine, except in some minor details which arise from 

 slight structural differences. For example, he describes the hairs 

 on the margin of the indusium, and the outside, as few and weak, 

 whereas I have always observed them to be stiffer than in others 

 of the order. He believes the functions of the hairs to be to catch 

 the pollen and detain it on the outside of the indusium. But 

 examination of many species of trie order leads me to think that 

 the marginal cilia are, first, intended to brush the pollen out of the 

 anthers as the style lengthens ; and second, to strain it out a little at 

 a time as the stigma grows outward. The function of the hairs on 

 the upper surface of the indusium I think is to protect the pollen
