CHAP. 14.—THE PANACES CENTAURION OR PHARNACION:
A fourth kind of panaces, discovered also by Chiron, is
known by the additional name of "centaurion:"1
it is also
called "pharnacion," from King Pharnaces, it being a matter
in dispute whether it was really discovered by Chiron or by
that prince. It is grown from seed,2
and the leaves of it are
longer than those of the other kinds, and serrated at the edge.
The root, which is odoriferous, is dried in the shade, and is
used for imparting an aroma to wine. Some writers distin-
guish two varieties of this plant-the one with a smooth leaf,
the other of a more delicate form.
