To K. E. S., L. C., and M. S. Wedgwood 4 [August 1862]1
My dear Angels!
I can call you nothing else.—
I never dreamed of your taking so much trouble; the enumeration will be invaluable.2 I will write this evening if possible & explain what I have very little doubt is the case with Lythrum, & which I am daily working to prove by most laborious crosses.—3
But I write now to ask whether you will be more angelic than angels & send me in tin, not tightly packed, with little damp (not wet) moss (perhaps tied round stems??) 2 or 3 flowers of both forms of Hottonia: I much wish to measure pollen & compare stigmas.—4
GoodBye | My dear Angels | C. Darwin
Their enumeration [of forms of Lythrum?] is invaluable. He will write later to explain what he is trying to prove about Lythrum through laborious crosses.
Asks for flowers of both forms of Hottonia to measure pollen and compare stigmas.
