My dear Sir Ferdinand
I have your letter of 10/102 and am very grateful for the specimens of Cycas Seemanni.
I shall carefully study the differences you point out between it and C. circinalis to which I fear nevertheless it is very nearly allied.
The section of the genera Cycas of which C. circinalis and C. Rumphii are the types is a very perplexing one as the different species seem to me to be little more than geographical races.
I wish I could get hold of your C. papuana if only in a small fragment.
As far as I can see Macrozamia is a good genus though perhaps distinguished rather by habit than by technical characters. Certainly in facies the Australian & S. African species have nothing in common and their origin can be diagnosed at a glance
Yours sincerely
W. T. Thiselton Dyer
Cycas circinalis
Cycas papuana
Cycas Rumphii
