HYBRIDISATION AND SYSTEMATIC ARRANGEMENT OF ORCHIDS. 221 
that morphological differences of the whole plant are a great obstacle. 
For example, the parents of Hpi-phronitis Veitchii look very different, but 
they both have a terminal inflorescence and conduplicate leaves; they 
are, therefore, not very different in their morphological structure. 
If these facts speak somewhat for my own systematic arrangement, and 
against that of Mr. Bentham, I should like to say that the merits of 
Bentham’s systematic arrangement generally, and especially that of 
orchids, are so great that they can only be slightly diminished by the in- 
formation which has been obtained since his time. 
I regret very much that I can give no results of orchid-hybridisaticns 
of my own. But the raising of hybrid orchids and bringing them up to 
the flowering stage requires such an amount of experience that it would 
be useless for me to name, in this Conference, where the most successful 
and eminent hybridisers of the world are meeting, the few interesting 
objects with which I have been personally concerned.
