FAMILIES OF FLOWERING PLANTS. 15 
lanceolate leaves and flowers in aments, the individuals of different 
sexes. The ovary consists of a single carpel which ripens into a dry 
stone fruit or drupe, as it is technically called. In habitat the plants 
are confined to deep swamps. 
Family Juglandaceae. Walnut Family. This represents another 
distinct order, and includes six genera, the most important being 
the walnut and /icoria, the 
hickory. The walnuts num- 
ber about 8 species, the 
hickories 15 or 20. They 
are natives of temperate re- 
gions, /iicoria being confined 
to North America. All are 
trees, with odd-pinnate leaves, 
and monoecious flowers, the 
staminate and pistillateaments 
being borne on the same 
branch. The fruit is the 
well-known nut of commerce. 
From Juglans we obtain the 
butternut, the black walnut, 
and the English walnut, 
which can be successfully cultivated in certain parts of the United 
States. Zicoria furnishes the shagbark hickory nut and the pecan. 
Allthe plants belonging to the foregoing orders are anemophilous, 
that is, they are fertilized by the agency of the wind, which blows the 
pollen from the staminate to the pistillateaments. There is therefore 
no need of a showily-colored perianth to attract insect visitors.
