Leaf
A leaf was a component of plants and trees.
During the autumn, leaves would fall to the ground.[source needed] People would then blow the leaves away with leaf blowers. In a dream, Rory Williams at first mistook the sound of the TARDIS materialising for the sound of one. (TV: Amy's Choice)
Uses
Tea plants had leaves, which were used to make tea. Raspberry leaf tea was good for the ailments of the throat. Tea leaves were also read by psychics to read the future. (TV: The Awakening, AUDIO: Casualties of War, TV: The Sun Makers, TV: The Curse of Clyde Langer)
Tobacco leaves were used in making cigarettes. (PROSE: History 101)

"The most important leaf in human history"
A large red ovate leaf, later dubbed 'the most important leaf in human history', caused the meeting of Dave Oswald and Ellie Ravenwood. On a windy day in 1981, this leaf fell from its tree and flew into Dave's face. This lead him to almost get hit by a car, before being saved by Ellie. After they began dating, and then got married, he kept the leaf, a symbol of their love.
Ellie would later put the leaf in the first page of her book, 101 Places to See, which she later passed on to her daughter, Clara Oswald.
Clara, who eventually became a companion of the Eleventh Doctor, used that leaf to feed Akhaten, a planet-like entity that fed off peoples' souls, and therefore stories. The leaf represented the history of the family, and well as potential futures. The infinite amount of stories in that one leaf bloated Akhaten, and he imploded. The leaf was destroyed in the process. (TV: The Rings of Akhaten)
Clara Oswald also had a maple leaf pressed in the pages of 101 Places to See. After saving Clara from having her mind being downloaded by The Great Intelligence, the Eleventh Doctor discovered the book containing the leaf. He asked Clara about and she told him, "That wasn't a leaf, that was page one." (TV: The Bells of Saint John)
The Doctor gave the leaf back to Clara in the end. (TV: The Name of the Doctor).
- It is unclear whether or not the maple leaf is the same as 'the most important leaf in human history'. It might however simply be a production error which caused the leaf to change form.
