190 THE UMBELLATE FAMILY. 
4, GH. Phellandrium, Lam. (fig. 426). Fine-leaved @.—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 @. 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. #l. 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 @. fluviatilis. [G. Phellandrium has 
an erect stem, 3-pinnate leaves, with very slender segments when sub- 
merged, and styles twice as long as the fruit. CG. fluviatilis, Colem., has 
an ascending stem, 2-pinnate leaves with obcuneate submerged segments, 
and styles thrice as long as the fruit. ]

XV. AETHUSA. 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 Seselz more in habit than in character. 
1, 44, 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 8 long, linear bracts, turned downwards towards 
the outside of the umbels, a character peculiar to this species among 
British Umbellifere. Fruit about 14 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. FGNICULUM. 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 Dill-seed), from which it has been separated, as having the 
fruit somewhat laterally compressed, not flattened from front to back.
