     A substance of very wide occurrence. It is found dissolved in
     the sap of the roots and rhizomes of many composite and other
     plants, as {Inula}, {Helianthus}, {Campanula}, etc., and is
     extracted by solution as a tasteless, white, semicrystalline


     substance, resembling starch, with which it is isomeric,
     having fructose units in place of most of the glucose units.
     It is intermediate in nature between starch and sugar, and
     replaces starch as the reserve food in Compositae. Called
