The leaf took its name from the Hobbit who introduced pipe-weed to the Shire, the original "Old Toby", Tobold Hornblower, who grew the first true pipe-weed in his gardens in the days of Isengrim Took II about the year 1070 of Shire-reckoning.
How Old Toby came by the plant is not recorded, for to his dying day he would not tell.
