Dear Sir

I am much obliged to you for sending me the Hybrid, gathered from a place to which I am so much attached as Maer.—²

You speak of the fruit of this hybrid, but say nothing on the seed. If it be a real hybrid & not a strong variety, I sh^d think, at least if protected from the pollen of its pure parents, that it would be utterly sterile, or very nearly so.— Perhaps this point w^d. be worth your attention.

With my thanks, I remain | Dear Sir | Yours faithfully | Ch. Darwin
