1. Any of the genus Lithops of succulent plants resembling stones.
   • 1978, Margaret J. Martin, Peter Richard Chapman, Succulents and Their Cultivation, Schribner, page 86:

     Lithops are self-sterile, so that seed will only be produced if the plant is pollinated from another specimen from a different clone or group. Yellow flowers will not fertilize white and vice-versa. There is not the same range of flower colour as shown by the conophytums; lithops’ flowers are either white or yellow.

   • 2008 January 3, Anne Raver, “No Need to Fly South to See Blossoms in Winter”, in New York Times‎:

     And the succulents house, which is kept a cool 60 degrees during the day and 50 to 55 degrees at night, holds aloes and lithops (which look like small stones), just beginning to bloom.

   • 2018, Andrea Afra, The Succulent Manual, unnumbered page:

     Lithops (‘Lithops’ singular) are easily one of Earth's weirdest plants making them highly popular with succulent lovers. They're also infamous for being easy to kill. In fact, I bet we'd be hard pressed to find someone who has never killed a Lithops unless they've just never had one, and that doesn't count.
