These two or three last days I have been observing wheat, and have convinced myself that L.Deslongchamps is in error about impregnation taking place in closed flowers; i.e., of course, I can judge only from external appearances.

By the way, R.Brown once told me that the use of the brush on stigma of grasses was unknown.
Do you know its use ?...
You say most truly about multiple creations and my notions.

If any one case could be proved, I should be smashed; but as I am writing my book, I try to take as much pains as possible to give the strongest cases opposed to me, and often such conjectures as occur to me.

I have been working your books as the richest (and vilest) mine against me; and what hard work I have had to get up your New Zealand Flora! As I have to quote you so often, I should like to refer to Muller's case of the Australian Alps.

Where is it published?
Is it a book?
A correct reference would be enough for me, though it is wrong even to quote without looking oneself.
