From R. D. Fitzgerald 15 March 1877
Surveyor Generals | Offices Sydney
15th March 77.
Dear Sir
Accept my best thanks for your works on fertilisation and for the flattering reference to my Australian Orchids in the last.1 I have read them with great interest. I regret that the third part of my Orchids as yet unpublished was not in your hands as I believe you would have been interested in at least one peculiar modification to be described in it.2 Though of course there can be no doubt from your experiments that a cross is of advantage in general I am compelled still to believe that there are some plants so constituted as to dispense with it altogether or only to be crossed under the most exceptional circumstances and that the numbers of individuals to be found in any species is dependent on other causes and not on this circumstance of whether their seed comes from self or cross-fertilisation.
I have discovered a curious series of forms in Thelymitra between dependent and independent fertilisation and am inclined to believe that self fertilisation was the ancient method to which they are reverting or from which they are departing3
I remain Dear Sir | Yours truly | Robt D Fitzgerald
