Sentence:  The whole town of Ryde could not supply a single leaf [of tea]; for as to what Mrs. Francis and the shop called by that name, it was not of Chinese growth. It did not indeed in the least resemble tea, either in smell or taste, or in any particular, unless in being a leaf: for it was in truth no other than a tobacco of the <WSD>mundungus</WSD> species. 
Meaning of the word marked with <WSD> tags:  Poor-quality tobacco with a foul, rancid, or putrid smell.
