It is a pleasure and profit to me to write to you, and as in your last you have touched on naturalised plants of Australia, I suppose you would not dislike to hear what I can say in answer.

At least I know you would not wish me to defer to your authority, as long as not convinced.
I quite agree to what you say about our agrarian plants being accustomed to cultivated land, and so no fair test.

Buckman has, I think, published this notion with respect to North America.

With respect to roadside plants, I cannot feel so sure that these ought to be excluded, as animals make roads in many wild countries.
