What is pine bush?

Famous quotes containing the words bush and/or pine:

“I come to one bush of berries so ripe it is a bush of flies,
Hanging their bluegreen bellies and their wing panes in a Chinese
screen.
The honey-feast of the berries has stunned them; they believe in
heaven.”
—Sylvia Plath (1932–1963)

“A few pieces of fat pine were a great treasure. It is interesting to remember how much of this food for fire is still concealed in the bowels of the earth.”
