Müller, J. F. T. to Darwin, C. R.

16 Feb 1870


Sends specimens of Passiflora and seeds for T. H. Farrer [letter enclosed with 7188].


As soon as the Passiflora, which was visited by humming birdsin my garden, flowers again next spring, I shall try fully toanswer Mr Farrer’s questions.—f1

I enclose a dried flower of this Passiflora; the longflower-stalk is dependent, but curved upwards at the end, so thatthe flower itself is upright.— You see, there is space enoughfor a hovering humming-birds head between the anthers and theentrance to the (nectarless) nectary.

There is now flowering with me a white Passiflora withdependent flowers, which is visited by humble-bees.—

The enclosed Passiflora-seeds may perhaps be acceptable to MrFarrer; at least they are from wild, not hybridised plants.f2
