Perennial glabrous usually branching herbs, with aromatic roots, ternately compound 

 leaves, and large compound umbels of white flowers. Involucre of several narrow mostly 

 deciduous bracts. Involucels of numerous linear bracts. Calyx-teeth obsolete. Stylopo- 

 dium conic. Fruit oblong or ovoid, scarcely flattened. Carpels dorsally compressed, the 

 ribs prominent, acute, separated by broad intervals; oil-tubes 2-6 in the intervals. Seed- 

 face flat or slightly concave. [Named from Liguria, where Lovage abounds.] 



About 20 species, natives of the northern hemisphere. Besides the following, some 7 others 

 occur in western North America. 



Leaves thin; fruit ovoid; southern species. i. L. Canadense. 



Leaves fleshy; fruit oblong; northern sea-coast species. 2. L. Scoticum.

Stout, erect, much branched above, 2-6 

 high. Leaves thin, those of the stem ses- 

 sile or nearly so, the lower and basal petioled, 

 often i wide, their primary divisions ternate, 

 the secondary ternate or pinnate; segments 

 ovate, or oval, iX~5 / l D gi acute at the apex, 

 rounded at the base, coarsely and sharply 

 serrate, or those of the uppermost leaves 

 linear-lanceolate and entire; umbels mostly 

 twice compound, sometimes 10' broad; bracts 

 of the involucre 2-6, linear; bracts of the 

 involucels several; pedicels i // -2 // long in 

 fruit; fruit ovoid, 2 // -3 // long with promi- 

 nent slightly winged ribs; oil-tubes 3-4 in 

 the intervals; seed angled on the back. 



In rich woods, southern Pennsylvania to 

 Georgia, Missouri and Kentucky. Ascends to 

 4000 ft. in North Carolina. June-Aug. 



2. Ligusticum Scoticum L.

(Fig. 2655.) 



Ligusticum Scoticum L. Sp. PI. 250. 1753. 

 Stem simple.or rarely slightly branched, 

 Ky-3 high. Leaves mostly biternate, 

 the segments thick and fleshy, broadly 

 obovate or oval, i'-4' long, shining, ob- 

 tuse or acute at the apex, narrowed or 

 the terminal one rounded at the base, 

 dentate with blunt or sharp teeth; um- 

 bels 2 / -4 / broad in fruit, the rays i'-3' 

 long; pedicels 2 // -5 // long; fruit oblong, 

 3 / '-5 // long, the ribs prominent and some- 

 what winged; seed rounded on the back. 



Along salt marshes, Connecticut to Labra- 

 dor and the lower St. Lawrence river. Also 

 on the Pacific coast and the shores of north-

 than the typical form. July-Aug.

Annual glabrous herbs, with pinnately dissected leaves, and compound umbels, both 

 terminal and opposite the leaves. Involucre none, or of a single bract. Bracts of the involu- 

 cels 1-5, setaceous, turned to one side. Calyx-teeth obsolete. Petals inflexed at the apex. 

 Stylopodium broad, thick. Fruit globose-ovoid, glabrous. Carpels dorsally compressed, 

 the ribs prominent, corky, acute, nearly equal; oil-tubes solitary in the intervals. Seed-face 

 flat. [Greek, burning, from the sharp taste.] 



A monotypic genus of Europe and Asia.
