To A. G. More    [30 June 1860]¹

Dear Sir

I write a line to thank you much for the kind manner with which you have received my rather unreasonable request—² If you find any pollen-masses removed, will you watch a group of the Bee-orchis for $\frac{1}{4}$ or $\frac{1}{2}$ an hour, & see what sort of insect visits them.

I have received account of pollen-masses of this plant having been seen on proboscis of a day-moth; but I cannot help feeling a little sceptical about the identification.—³ If you send any other orchids perhaps you would kindly enclose a Bee-orchis, (especially if you find one or more with pollen-masses removed) for this summer I have as yet searched in vain for specimen near my home; & I want to have pollen-masses for standard of comparison with those observed on the probosces of moths.—

The Spiranthes would be especially valuable to me & the Epipactis.

I shall return home on next Thursday (5^th) (to Down Bromley Kent) & on Monday 9^th or 10^th I shall go to Rev^d C. Langton’s

Hartfield

Tonbridge Wells.—⁴

I will venture to tell you my movements later, as I fear I shall not be stationary at home for some little time.—

With very sincere thanks I remain | Dear Sir | Yours truly obliged | Ch. Darwin
