Grass tree

[Dave Paprocki]

An Australian plant of the genus Xanthorrhoea, having a
thick trunk crowned with a dense tuft of pendulous, grasslike leaves,
from the center of which arises a long stem, bearing at its summit a
dense flower spike looking somewhat like a large cat-tail. These plants
are often called blackboys from the large trunks denuded and
blackened by fire. They yield two kinds of fragrant resin, called
Botany-bay gum, and Gum Acaroides.
