My dear M^r Dyer

Hearty thanks for all sorts of information in 2 last letters. I have given you too much trouble about the leaves on Pinguicula— Cast the whole subject on one side. Erica tetralix is far the most important case for me.— Thank M^r. Smith for Heath seeds.—² I have written to D^r. Moore, & used your name.—³

I sh^d. be an ungrateful & ungracious dog if I hesitated for a moment about your communicating anything which you may think fit to Hort. Soc.— I do not understand that you want me to draw up a paper, & for this I really have not time or strength. But I enclose memoranda, on which I think you may rely, but you must remember that I am almost daily at work.—⁴

I am very glad you will hereafter continue to work out Nepenthes.⁵ Huxley⁶ has been here, & tells me what hard work you have at present.—

Now will you communicate the substance of what follows to Hooker.— I am getting much overworked & I shall never publish on Drosera &c if I begin on other subjects. Therefore I am sure that I had better defer my work on movements of leaves from rain & on the bloom or waxy secretion on leaves till next summer; though to do so goes to my heart.⁷

Now can Hooker allow me to keep the young Eucalypti & Acacias & Cassias till next summer. As far as I know I have only 2 precious plants from Kew & both these, I grieve to say, are in a deplorable condition. We got Mimosa [Peruviana] into a splendid state, & it grew up 2 or 3 feet in height in a most healthy condition; & then I suspect it got too much heat & suddenly turned all yellow like a maple in autumn. Acacia farnesiana is the other plant;⁸ & we have tried little water & a modest supply & cannot keep it in health. It sometimes recovers for a space & then goes back. Shall I return this in its present disgraceful condition? And may I keep Mimosa [Peruviana] for the chance of its recovery, for there are a few all-important observations yet to be made on it. Sometime let me hear what Hooker thinks about this

These 2 plants have troubled me much. Forgive the length of this letter.—

Yours most sincerely | Ch. Darwin

P.S. If I can get English Utricularia I sh^d extremely like to examine the epiphytic species, & will then let you know.—⁹
