1 Species known everywhere. A poisonous plant, especially the roots. Leaves and berries dangerous 

 and violent purgative. The berries infused in brandy are used in cases of chronic Rheumatism resulting 

 from syphilitic diseases. (Barton.) The thickened sap of the berries is also used against scrofulas, and 

 even is said to have cured Cancer. The young shoots of the plant in spring lose their acridity by boiling, 

 and are said to be better than asparagus. 



2 Mostly introduced weeds. The leaves and roots of some of them — the Spinac (Spinacia oleraceo), the 

 Beet {Beta vulgaris) — give a wholesome food. Those growing near the sea contain Soda, which is 

 obtained from their ashes. 



3 Mostly introduced weeds. 



* In this family, we find plants with bitter, aromatic, and purgative roots, like the Rhubarb ; or with 

 pleasant acid and wholesome stems and leaves, like the stems of the Rhubarb and the leaves of the Sorrel. 

 Some have mealy seeds, as the Buckwheat (Fagopyrum esculentum). One of our very common species, 

 the Knot-grass or door-weed (Polygoyium aviculare), has the seeds emetic and purgative. I have not 

 seen the Buckwheat in Arkansas.
