 Tourn. cor. ex herb. Juss. The cut in Bauh. hist. 3. p. 2. p. 

 57 and 58. f. 1. agrees well with this plant, but the figure of P.

 trifid ; petioles broad, sheathing. 1. H. Native of Japan, on

 at the base ; umbels pedunculate, of 2-3 rays ; involucrum of 

 2-3 leaves ; umbellules many-flowered ; petals inflexedly cor- 

 date at the apex, i; . H. Native of New Zealand. Bowlesia 

 geniculata, Spreng. umb. spec. 14. t. 5. f. 11. But it certainly 

 is not a species of Bowlesia, from the calyx being without teeth.

 wanting ; involucels of few leaves. Flowers white. Plants with 

 the habit of Angelica.

 upper ones less compound ; leaflets broad, smooth, rough edged, 

 finely and sharply serrated, partly cut or lobed, sometimes 3- 

 cleft ; sheaths of leaves dilated. 11 . H. Native of Europe 

 and Newfoundland, in rather moist meadows and in woods ; in 

 Scotland, on the banks of the Clyde in several places, and in the 

 Isle of Bute, near Mount Stuart. Professor Hooker mentions 

 several stations in Scotland, chiefly about ancient residences, 

 indicating its being a naturalised plant. Smith, engl. bot. t.

 with a figure. Flowers white or pale flesh-coloured. Root 

 fleshy, tuberous, somewhat creeping, of an aromatic and acrid 

 quality ; long supposed a sovereign counter-poison, and cele- 

 brated as a powerful external as well as internal remedy in nu- 

 merous disorders. It is said to be a sudorific, diuretic, and 

 sialogogue ; recommended in dropsy and debilities of the sto- 

 mach and bowels ; an infusion of it in wine is said to have 

 cured quartans that have resisted the bark. When chewed it 

 excites a copious flow of saliva, with a warm and not disagree- 

 able sensation in the gums, and frequently cures the rheumatic 

 toothache. The mericarps are broadly winged. The plant is 

 cultivated in several places for the London market.
