Levisticum
(a corruption of Ligustikon, the name given by Dioscorides to another Umbellifer). ORD. Umbelliferoe. A monotypic genus. L. officinale is a hardy herbaceous perennial, with yellow flowers, and ternately-decompound leaves, having deeply-toothed obovate-cuneate leaflets. It is of no horticultural value, and is rarely seen out of botanic gardens. A form having variegated leaves is offered by Continental seedsmen.
