My dear Farrer
I have just received from Fritz Müller the enclosed seeds “of a third species of Passiflora, the flowers of which are visited fertilised by a large Humble-bee.”2
Yours most sincerely | Ch. Darwin
We return home early on Friday morning: if you were in this direction on Thursday & would feel the least inclination to come to luncheon at 1 o clock, I am sure I need not say that we shd. all be very glad indeed to see you.—
