“ Tous-les-mois, or Tulema arrowroot, also from the West Indies, is obtained from several species of Canna, a genus allied to Maranta, and cultivated in the same manner. The granules of tous-les-mois are readily distinguishable by their very large size (fig. 5) . East Indian arrowroot is obtained from the root-stocks of several species of the genus Curcuma (nat. ord. Zingiberaceae) , chiefly C. angustifolia, a native of central India. Brazilian arrowroot is the starch of the cassava plant, a species of Manihot (fig. 6) , which when agglutinated on hot plates forms the tapioca of commerce. ”
