Word to describe flavor of anise, licorice, and fennel?

Kenneth T. Farrell describes the aroma and flavor of fennel seed in his book Spices, Condiments and Seasonings:

The odor of the essential oil has been characterized as being aromatic, pleasantly fresh, warm, spicy, aniselike, slightly camphoraceous, changing to a heavier camphoraceous note when dried out, leaving an anetholic back note. The flavor has also been described as being warm, spicy, aniselike, aromatic, green, herbaceous, initially bitter, then sweet, with a fresh, slightly bitter, aftertaste.
