190 THE UMBELLATE FAMILY. [CEnanthe. 



4. G3. Phellandrium, Lam. (fig. 426). Fine-leaved (E, Stem rooting 

 at the base, and either thickened or erect, or elongated and creeping, or 

 floating, according to the situation it grows in, the flowering branches 

 erect or ascending. Stem-leaves twice or thrice pinnate, with small 

 oblong and entire, or cuneate and lobed segments ; or, when under 

 water, all the lobes are narrow and long, sometimes capillary. Umbels 

 much smaller than in CE. crocata, and almost all .on very short peduncles, 

 either opposite to the leaves or in the forks of the branches. Rays 

 seldom above 12. No general involucre, and but very small, narrow 

 bracts to the partial ones. Fruits rather different from those of the 

 other species, being shortly pedicellate, cylindrical, with scarcely pro- 

 minent, broad ribs, and the calycine teeth very minute. 



In wet ditches, ponds, and along rivers and streams, throughout the 

 temperate parts of Europe and Russian Asia. Not uncommon in 

 England and Ireland, but rare in Scotland, where it has not been found 

 north of Haddington. Fl. summer. A Variety growing usually in deeper 

 or running water, with the lower part of the stem much elongated and 

 slender, has been distinguished as CE. fluviatilis. [CE. Phellandrium has 

 an erect stem, 3-pinnate leaves, with very slender segments when sub- 

 merged, and styles twice as long as the fruit. CE. fluviatilis, Golem., has 

 an ascending stem, 2-pinnate leaves with obcuneate submerged segments 

 and styles thrice as long as the fruit.] 



XV. JETHUSA. FOOL'S PARSLEY. 



Leaves dissected. Umbels compound, with partial involucres. Petals 

 white, notched, with an inflected point. Fruit ovoid, not laterally com- 

 pressed, without visible calycine teeth. Carpels with 5 thick, prominent 

 ribs, and narrow furrows, with a vitta under each. 



A single species, differing from Seseli more in habit than in character. 



1. 2E. Cynapium, Linn. (fig. 427). Fool's Parsley. An erect, gla- 

 brous, leafy annual, 1 to 2 feet high, with forked branches, emitting a 

 nauseous smell when rubbed. Leaves of a bright green, twice or thrice 

 pinnate, the segments ovate-lanceolate, more or less deeply cut into 

 narrow lobes. Umbels on long peduncles, either terminal or opposite 

 to the leaves, of 8 to 12 rays, usually without general involucres. 

 Partial involucres of 2 or 3 long, linear bracts, turned downwards towards 

 the outside of the umbels, a character peculiar to this species among 

 British Umbelliferce. Fruit about 1^ lines long, with very small reflected 

 styles. 



A common weed in fields and gardens, throughout Europe and Russian 

 Asia, except the extreme north. Abundant in England, but does not 

 appear to extend beyond Elgin in Scotland ; it is a native of Ireland. 

 Fl. summer and autumn. 



XVI. FCENICULUM. FENNEL. 



Leaves finely dissected. Umbels compound, without involucres. 

 Petals yellow, entire, inflected at the top, but not pointed. Fruit oval, 

 slightly compressed laterally, without visible calycine teeth. Carpels 

 with 5 prominent ribs, and single vittas under the furrows. 



A single, or perhaps two species, with the yellow flowers and habit of 

 Anethum (or Dili-seed), from which it has been separated, as having th6 

 fruit somewhat laterally comr> r assed, not flattened from front, to back.
