UMBELLIFEHJE. 255 



In moist woods, and marshy places, especially near streams, throughout 

 Europe and Eussian Asia to tlie Arctic regions. Abundant in Britain. 

 Fl. late in summer. 



The garden Angelica {A. Archangelica, Eng. Bet. t. 2561), a native of 

 northern and eastern Europe, long cultivated for confectionery, is not wild 

 in Britain. 



XXV. FEUCEDAN. PEUCEDANUM. 



Leaves dissected. Umbels compound, with partial involucres of many 

 bracts. Petals white or yellowish, entire or notched, witli an inflected point. 

 Pruit flattened from front to back ; the calyeine teeth very small or indis- 

 tinct. Carpels broad, with 3 prominent ribs on the back, the edges ex- 

 panded into a wing, those of the two carpels so close as to form a single 

 edge to the fruit before the carpels separate. Vittas single under the 

 furrows. 



A large genus, widely spread over Europe, Asia, and North America, 

 scarcely differing from Heraaleum except in the more evident ribs of the 

 carpels, the more slender vittas, and generally in habit. 



Segments of the leaves narrow-oblong or linear. 



Leaves several times ternate. Flowers yellowisli 1. Sea F. 



Leaves twice or three times pinnate. Flowers white 2. Marsh P. 



Leaves of 3 broad segments, each 3 inches long, and often 3-lobed ... 3. Broad P. 



The Dillseed {Anetlium graveolens), often cultivated as a condiment, has 

 the fruit of a Pencedan with the fine leaves of a Fennel. 



1. Sea Peucedan. Peucedanum officinale, Linn. 

 (Eng. Bot. t. 1767. Sog's Fennel or Sulphur-weed.) 



A glabrous perennial, with erect, branching stems, 2 or even 3 feet high. 

 Leaves 3, 4, or 5 times ternate, with narrow-Unear entire segments, often 

 above 2 inches long. Umbels large, of 20 or more rays, with pale yellow 

 flowers. Bracts of the general involucre very few or wanting ; those of the 

 partial involucre very narrow and shorter than the pedicels. Fruit broadly 

 oval, near 3 lines long. 



In meadows and moist pastvires, in central and eastern Europe and Eus- 

 sian Asia, or near tlie sea in western Europe. Scarce in Britain : forms 

 of the parsley (Enanth or of the meadotv Silaiis have been so frequently 

 mistaken for it, that the only certain stations for the true Peucedan are the 

 salt-marshes of Kent and Essex. Fl. summer and autumn. 



2. IKIarsli Peucedan. Peucedanum palustre, McBnch. 

 (Selinum, Eng. Bot. t. 229. Hog's Fennel or 3IilJc ParsUy.) 



Tall and erect like the last, but often hairy at the base, and the juice is 

 milky. Leaves twice or thrice pinnate rather than ternate, with much 

 shorter segments, varying from oblong to linear, and seldom exceeding half 

 an inch. Umbels not so large as in the sea p., although consisting of as 

 many rays. Flowers white. Involucres, both general and partial, of several 

 lanceolate or linear bracts, with fine points. Fruit broadly oval, about 

 2 lines long. 



In wet meadows and marshes, in central, eastern, and northern Europe, 

 and Eussian Asia, to the Arctic Circle. Apparently wanting in west- 

 ern France although it extends into Spain. Like the sea P. very local in
