and above all, Lettuces and Jerusalem Artichokes : the former the leaves of Lactuca 

 sativa, the latter the tubers of Helianthus tubero^us. To these some have added the 

 roots of the Dahlia, but their strong turpentine taste renders them unfit for food. 

 Among the less kno^^^l esculents are Helminthia echioides, whose leaves are l)oiled and 

 pickled in Greece. — Sihth. Scorzonera glastifolia has roots whose (juality is similar to 

 that of S. hispanica ; S. delicinsa is the species most cultivated as an esculent at 

 Palermo ; the gummy root of Scorzonera tuberosa is eaten by the Calmucks, ami the 

 young roots of Myscolus (Scolymus) hispanicus are esculent when young, l)ut they are 

 diuretic. The leaves of Cichorium Intybus have been found to dye blue when prepared 

 iu the same manner as Woad. — Chem. Gaz. 1845, p. 340.
