Lily of The Valley Phenomenon
See also: bourgeonalThe odor of lily of the valley, specifically the ligand bourgeonal, attracts mammal sperm in a dramatic manner. The 2003 discovery of this phenomenon prompted a new wave of research into odor reception, but no evidence was found that the female sex organ has similar odors of any kind. A 2012 study demonstrated instead that at high concentrations, bourgeonal imitated the role of progesterone in stimulating sperm to swim (chemotaxis), a process unrelated to odor reception.

“I am haunted by numberless islands, many a Danaan shore,
Where Time would surely forget us, and Sorrow come near us no more;
Soon far from the rose and the lily and fret of the flames would we be,
Were we only white birds, my beloved, buoyed out on the foam of the sea!”
—William Butler Yeats (1865–1939)
“I see before me now a traveling army halting,
Below a fertile valley spread, with barns and the orchards of summer,
Behind, the terraced sides of a mountain, abrupt, in places rising high,”
—Walt Whitman (1819–1892)
“When the ice is covered with snow, I do not suspect the wealth under my feet; that there is as good as a mine under me wherever I go. How many pickerel are poised on easy fin fathoms below the loaded wain! The revolution of the seasons must be a curious phenomenon to them. At length the sun and wind brush aside their curtain, and they see the heavens again.”
—Henry David Thoreau (1817–1862)
