BOTANY. 109 
Tribe 4. Phytolaccee. Testa of crustaceous grains. Plants seldom extra- 
tropical. Examples: Phytolacca, Ercilla, Giesekia, Microtea, &c. The 
most important North American plant of this family is Phytolacca decandra 
or Pokeberry. The young shoots are boiled as greens, and the rich purple 
juice of the berrics has been used as red ink, and also in the coloration of 
wines. ‘The ashes of the young plants contain a large amount of potash. 
OrveR 76. CHENopopiAce® or AnrrRiptices, the Goosefoot Family. 
Perianth deeply divided, sometimes tubular at the base, persistent without 
bracts ; zestivation imbricate. Stamens inserted into the base of the perianth 
or hypogynous, opposite to its segments, and equal to them in number, or 
fewer. Ovary single, superior, or sometimes cohering to the tube of the 
perianth, one-celled ; ovule solitary, attached to the base of the cell; style 
~two- to four-divided; stigmas simple. Fruit membranous, indehiscent, in- 
closed in the calyx, sometimes fleshy. Seed erect or resupinate; embryo 
curved, round farinaceous albumen; often like a horse-shoe, or spiral, or 
doubled together without albumen ; radicle next the hilum. Herbs or under- 
shrubs, with alternate, sometimes opposite, exstipulate leaves, and hermaphyro- 
dite or unisexual flowers. They are found in almost all parts of the world, 
but do not abound in the tropics. Most of the plants are inconspicuous weeds. 
There are sixty-seven known genera, and 372 species. 
Moquin Tandon has divided this family into seven tribes arranged under 
two sub-orders, tie first, with the embryo curved round the albumen (Cyclolo- 
beze) ; the other with a spiral embryo and no albumen (Spirolobez). 
A Cyclolobee. 
Tribe 1. Anserinee. Stem unjointed, with membranous flat leaves. 
Flowers hermaphrodite, all of the same form. Pericarp free. Seed with two 
integuments, the outer usually crustaceous. Examples: Chenopodium, Beta, 
Ambrina, Blitum, &c. 
’ Tribe 2. Spinaciee. Stem like the last. Flowers polygamous or 
diclinous ; males different from the females, or the calyx often reduced to 
two valves with the fruit compressed, most often free. Seed with a single or 
double integument. Examples: Atriplex, Spinacia, Obione, Acnida, &c. 
Tribe 3. Camphorosmea. Stem and leaves generally like the last, the 
leaves rarely fleshy and semicylindrical. Flowers hermaphrodite or poly- 
gamous. Pericarp free. Tegument of the seed simple. Examples: Kochia, 
Camphorosma, &ce. 
Tribe 4. Corispermee. Stem unjointed, with coriaceous, flat, linear leaves. 
Flowers hermaphrodite, all of the same form. Pericarp adherent. Seed 
embraced by a simple integument which is compounded with the pericarp. 
Examples : Anthochlamys, Corispermum. 
Tribe 5. Salicorniee. Stem jointed, often leafless. Flowers hermaphro- 
dite, all of the same form, lodged in cavities of the rachis or in the articula- 
tions. Pericarp free or adherent. Seed with one or two integuments. 
Example: Salicornia.
