Dear Mrs Treat

I congratulate you on your splendid Botanical success in finding the Water Lily & Amaryllis.2 Alas I know nothing of systematical botany. The specimens which you have sent of Utricularia are most beautiful & excellently preserved. I shall feel great interest in reading your account of them when published.3

I am sorry to say that I never received the article in Harpers on the sensitivity of the valve in Utricularia,— a subject which drives me half mad.—4 If you have been able to prove either side of the case, I beg you to tell me exact title & date of the number, which I can then easily procure.

If the Nymphaea is presumed by Dr. Gray to be a new species, I am sure Dr Hooker wd be very glad of a specimen.—5 I hope that you received my Book on Insectivorous Plants, copies of which were despatched at the same time to you, Asa Gray & Dr Canby.6

Dear Madam | Yours very faithfully | Ch. Darwin

I have thought it best to address this to Vineland


Congratulations on finding water-lily.
