from one flower in the young stage to the stigma of a flower in a 
correspondingly young stage; from one flower in a young stage 
to the stigma of another flower in an old stage, and otherwise. 
These experiments were, however, put an end to by the close of the 
flowering season. That the pollen is not sterile is proved by the 
fact that it germinated slightly in a weak solution of sugar (2 per 
cent.), also that a ripe seed was obtained, according to Mr. L. 
Stewart, Foreman of the Glass Department, Royal Botanic Garden, 
Edinburgh, when pollen was transferred from a Deherainia plant 
to a Theophrasta. The microscopical character of the stamen is 
unique in many respects, and offers suggestions for experiments 
in artificial fertilisation, for which it is hoped there will again be 
opportunity. So far the pollen of Dehevainia smaragdina has 
shown itself for the fertilisation of its own species, practically 
sterile.
