SALTBUSH FAMILY 431 



mealy; leaves rhombic-ovate, sinuate-dentate below or about the middle, the 

 uppermost varying to lanceolate and subentire, 1 to 2 inches long, whiter 

 beneath than above; flowers densely clustered in close spikes, the panicle 

 strict and close or somewhat spreading; calyx about % line wide in fruit, the 

 lobes strongly carinate. 



Common European weed in half-cultivated lands. July-Oct. Also called 

 Lambs Quarters; the herbage makes excellent boiled greens when taken 

 young. Var. VIRIDE Moq. Leaves bright green on both sides or only slightly 

 mealy beneath; inflorescence less dense. Widely distributed but not as com- 

 mon as the species.
