The fruit below the corolla (called cypsela) is 4½-5 mm long, 1½-3 mm wide, narrowed at the tip, where it carries a collar, with a shaggy appearance due to white hairs.
The plants produce a pungent smell when touched, due to the aromatic oil, which contains 42-53% β-eudesmol, 17½% trans-nerolidol, 5-8½% linalool and about 2½% guaiol [REF].
