PHYTOLACCACEAE Pokeweed Family 
Herbs (ours) or shrubs or trees. Leaves alternate, simple, entire; stipules mostly 
none (so in ours). Flowers perfect (ours) or monoicous or polygamous, regular, usually 
in racemes (so in ours). Perianth 4—5-parted or of 4—5 distinct segments; segments all 
alike. Stamens as many as the perianth-segments, or more numerous (ours) ; filaments 
filaform, united at base or distinct. Ovary superior, several-celled in most genera (10 in 
ours); cells l-ovuled; styles as many as the carpels, short or none; stigmas filiform. 
Fruit a berry (ours) or capsule or samara. 
PHYTOLACCA POKE-BERRY 
Perennial, 1.2—-3.6 m. high (ours). Racemes terminal but apparently opposite 
the leaves. Pedicels bracted at the base. Perianth-segments almost distinct, rounded, 
persistent. Stamens 4—10 (10 in ours), on base of perianth. Ovary globose; carpels 
5—15 (10 in ours), distinct or somewhat united. Berry dark-purple (ours), depressed- 
globose. Seed compressed. (Gk. phyton—plant, L. lacca—lacquer; referring to the 
red juice in the berries.) E. P. decandra L. 
AIZOCAEAE Carpet-weed Family 
Herbs, rarely somewhat woody (not ours) ; stems mostly prostrate, branching. Leaves 
basal or opposite or whorled (ours) ; stipules none, or scarious (ours), or the base of the
