To Daniel Oliver 8 October 1
Down. | Bromley. | Kent. S.E.
My dear Sir
I am perfectly ashamed to trouble Hooker again.— Would you have kindness to look at well-opened flower of Stanhopea saccata & see whether any nectar is in hollowed out base or cup of Labellum; or in other species of Stanhopea, if they have hollowed out base or cup to Labellum.—
I have particular reason to enquire; but I daresay the plant will have none, though it ought to have some.—2 But Nature, as Agassiz says, does not lie,3 & therefore it must have nectar,—else a theory of mine is wrong which is clearly impossible!—
In Haste | Ever yours | C. Darwin
Asks DO to look for nectar in Stanhopea saccata labellum. CD’s theory predicts nectar should be present, but afraid there is none.
