b. Marsh Parsley CE. (CE. Lachenalii, Brit. Fl.) Flowers of a purer 

 white ; the fruiting pedicels less conspicuous, but little enlarged at the 

 top ; the fruits either cylindrical or narrowed at the base. In wet 

 marshes, and especially in maritime salt-marshes. 



3. Hemlock (Enanth. CEnanthe crocata, Linn. (Fig. 418.) 

 (Eng. Bot. t. 2313.) 



A stout, branched species, attaining 3 

 to 5 feet ; the root-fibres forming thick, 

 elongated tubers close to the stock ; the 

 juice both of the stem and roots be- 

 coming yellow when exposed to the air. 

 Leaves twice or thrice pinnate ; the seg- 

 ments much larger than in the other 

 species, always above half an inch long, 

 broadly cuneate or rounded, and deeply 

 cut into 3 or 5 lobes. Umbels onlong, ter- 

 minal peduncles, with 15 to 20 rays, 2 

 inches long or more ; the bracts of the 

 involucres small and linear, several in the 

 partial ones, few or none under the ge- 

 neral umbel. The pedicellate flowers at 

 the circumference of the partial umbels 

 are mostly but not always barren, the 

 central fertile ones almost sessile. Fruit 

 somewhat corky, the ribs broad and 

 scarcely prominent. 



In wet ditches, and along rivers and streams in western Europe, ex- 

 tending eastward into Italy, but not into central France. Common in 

 England, Ireland, and southern Scotland. FL summer.

4. Fine-leaved CEnanth. CEnanthe Phellandrium, Lam. 

 (Fig. 419.) 



(Phellandrium aquaticum, Eng. Bot. t. 684.) 



Stem rooting at the base, and either thickened and erect, or elon- 

 gated 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 the Hemlock CE.,
