From Daniel Oliver   [after 8 October 1861]1

[Kew]

I find no trace of nectar or other secretion in the hollow base of labell of St. Saccata2

The papillae wh. clothe it are more or less moist, but no accumulation as a drop—

The draft of Oliver’s letter is written on the back of the letter to Daniel Oliver, 8 October [1861].
