Order CXXXI. ARACE^. Aroids. 



Herbs with a creeping rhizome or corm, and an acrid or pungent juice, with the 

 leaves simple or compound, often veiny, and the flowers mostly dicMnoua and naked. 

 Inflorescence a spadix, dense-flowered, naked or 

 mostly surrounded with a large spathe. Perianth 

 none, or of 4 to 6 scales. Stamens hypogynous, 



with ovate-extrorse anthers. Ovary free, stigma , . , . . 



sessile. Fruit baccate or dry, seeds albuminous, / : vSttte'". '■ \ ^^^^

Properties. An acrid, volatile principle pervades the 

 order, wMch Is, in some instances, so concentrated as to 

 beoome poisonous. The corms and rhizomas abound also in 

 staroh, which in some cases when the volatile acridity is ex- >^ ly^f/ ^' 



SBlled in drying or cooking, is edible and notricious, as in \\\ ^t// ^v
