Order CVI. CHENOPODIACEiE.— Chenopods. 



Herbs or undershruhs, with alternate (rarelj' opposite) leaves without stipules. 



pis. inconspicuous, generally perfect, often dioecious or polygamous. 



Cal. deeply divided often tubular at base, imbricate in estivation. 



Sta. from the base of the calyx, as many as its lobes or fewer, and opposite to them. 



Ova. 1, with 1 ovule attached to its base within. Styles 2—4, rarely 1. 



Fr. a utricle. Embryo usually curved around fleshy albumen. 



Genera 63, species 360, oilen maritime plants, and more generally weeds, aboiuiding in the northern

Properties.— Some are useful for food, as the beet, mangel-tcurtzel, orache, spinach, ^c. Others con- 

 tain an essential oil, which renders them tonic, antispasmodic and anthelmintic ; as Chenopodium 

 botrys, C. ambrosioides, C. anthelminticum ; the latter yields the officinal loorm-seed oil. SaJsoli, Sali- 

 cornia and other sea-side species yield soda from their ashes in great abundance.
