From Fritz Müller 16 February 1870
As soon as the Passiflora, which was visited by humming birds in my garden, flowers again next spring, I shall try fully to answer Mr Farrer’s questions.—1
I enclose a dried flower of this Passiflora; the long flower-stalk is dependent, but curved upwards at the end, so that the flower itself is upright.— You see, there is space enough for a hovering humming-birds head between the anthers and the entrance to the (nectarless) nectary.
There is now flowering with me a white Passiflora with dependent flowers, which is visited by humble-bees.—
The enclosed Passiflora-seeds may perhaps be acceptable to Mr Farrer; at least they are from wild, not hybridised plants.2
Itajahy, Febr. 16. 1870.
Sends specimens of Passiflora and seeds for T. H. Farrer [letter enclosed with 7188].
