CLASS V. ORDER II. J CHENOPODIUM. 42iJ 



lateral spikes, intcrmixeil with small lanceolate toothed or simple 

 leaves. Perianth very small, of live ovate scarcely acute segments. 

 Stamens with slender filaments, longer than the perianth, with small 

 two lobed anthers. Fruit very small, like grains of sand, surrounded 

 by the dried perianth. Seed smooth, shining, enveloped in a very thin 

 pale membrane. 



Habitat. — Dunghills, under walls,, and waste places ; not uncommon. 



Annual ; flowering in August and September. 



In drying, the alkaline salt contained in the juices of the plant 

 crystalizes with a white frosted appearance upon the stem and petioTes. 

 The-fiowers on the lateral parts of the spikes are frequently with seg- 

 ments only having three divisions, and also with only three stamens, 

 while those on the top and upper parts have five segments and 

 stamens.

 with two teeth larger than the others near the base, a glaucous green 

 above, sometimes purplish, white and mealy beneath. Flowers small, 

 in dense close clustered branched spikes, both terminal and lateral, 

 leafless, or with two or three leaves at the base. Perianth of Ave 

 small smooth (ibtuse segments. Stamens with short filaments and 

 yellow two lobed anthers. Styles very short. Fruit roundish, flat- 

 ened, covered with a thin membrane, and crowned by the persistent
