CLAM V. ORDHR II.] TORDYLIUM. 393 



Channels very shallow, with from one to three slender vittce. Albumen 

 very flat. 



Habitat. Banks and waste ground ; rare. About London, Oxford, 

 and Eton. 



Annual ; flowering in June and July. 



This is a larger and taller plant than the following, with more nu- 

 merous and more lanceolate leaflets. Scarcely a native plant, though 

 common on the Continent, especially in Italy. 



2. T. ojfi'cinale, Linn. (Fig. 453.) Small Hart-wort. Stem clothed 

 with soft reversed hairs; leaves pinnate; leaflets crenated, cut, ovate; 

 involucre as long as the umbel ; fruit with a smooth crenated border 

 and hairy disk, the two outer petals of the flowers of the ray each with 

 one very large lobe.

Root small, tapering. Stem erect, branched, and spreading, from 

 ten to eighteen inches high, round, furrowed, clothed with soft de- 

 flexed hairs, leafy. Leaves roughish, hairy, simply pinnate, leaflets 

 few, ovate, roundish, variously lobed and notched, and irregularly 

 crenated or obtusely serrated, the terminal one largest, footstalks 

 channeled above, the base dilated into a thin striated membrane. 

 Umbels lateral and terminal, the general of numerous unequal rays, 

 the partial of numerous short ones. Flowers numerous, unequal, 

 white, those of the disk small, and nearly equal, but those of the cir- 

 cumference very unequal, the two outer petals very much larger than 

 the others, each with one very large obovate lobe, and one very small 

 one. Involucre both general and partial of numerous narrow linear 

 segments, as long as the umbels, and downy. Calyx of five small 

 teeth. Petals, except the two outer ones of the flowers of the circum- 

 ference, small, inversely heart-shaped, with a small inflexed point. 

 Stamens on slender filaments, with small ovate anthers. Styles 

 slender, with obtuse stigmas, and the disk convex. Fruit very beau- 

 tiful, orbicular, with a thick pale deeply notched or crenated smooth 

 border around the hairy disk. Carpels very much flattened, with five 

 very slender filiform ridges, three at the back an equal distance from 

 each other, the two lateral ones more distant, near the thickened 

 margin. Channels very shallow, with three viitce, each of which is 

 separated by a furrow. Albumen flat. 



Habitat. Cultivated fields, near London. 



Annual ; flowering in June and July. 



This species, which is made a separate genus of by Hoffmann, on 

 account of the three viltse in each channel being separated by a furrow, 

 is a very doubtful native. It was formerly called Seseli creticum, and
