246 THE TJMBELLATE FAMILY. 



Fruit bi'oadly ovoid, somewhat coinpressed laterally. Carpels with 5 slender 

 ribs, and several vittas under each interstice. 



A small genus spread over almost all temperate regions of the globe ; re- 

 sembling A2niim in the sliape of the fruit, but witli the calyx-teeth usually 

 prominent as in Cowhane, and ditfering from both in the more numerous 

 vittas. 



Stem usually 3 or 4 feet. Umbels all terminal ; rays usually 15 to 20 . 1. Broad S. 

 Stem much branched, seldom above 2 feet. Umbels mostly lateral ; rays 



usually 10 to 15 2. Leaser S. 



1. Broad Slum. Slum latifolium, Linn. 

 (Eng. Bet. t. 20-i. Water Parsnip.) 



A. glabrous perennial, with a creeping rootstock, and stout erect stems 

 2 to 4 feet high. Lower leaves very long, with 6 to 10 pairs of ovate- 

 lanceolate segments, sessile on the common stalk, tootlied or rarely slightly 

 lobed, often 2 to 4 inches long ; the upper leaves shorter, with fewer and 

 smaller segments. Umbels rather large, of 15 to 20 rays, and all terminal. 

 Tnvokicres, both general and partial, of several lanceolate bracts, often toothed. 

 Fruits about Ij lines long and broad, the small pointed teeth of the calyx 

 usually very distinct. 



In wet ditches and on the edges of streams, throughout Europe, except 

 tlie extreme north ; replaced in Asia by a closely allied species or variety. 

 In Britain, not mifrequent in southern and central England and in Ireland, 

 wore rare in the north, and very local ui southern Scotland. FL summer. 



2. Iiesser Siuiu. Slum angustifolium, Linn. 

 (Eng. Bot. t. 139.) 



Resembles the broad S., but is not so tail, more branched and leafy, seldom 

 2 feet high, and in dried-up ditches often less than a foot, and decumbent. 

 Segments of the leaves smaller, 8 to 10 pairs in the lower leaves, fewer in the 

 upper ones, from ovate to ovate-lanceolate, more deeply and sharply toothed 

 or lobed than m the broad S. Umbels more numerous, smaller, on shorter 

 peduncles, mostly lateral, with 8 to 12 or 15, rarely more, rays. Involucral 

 bracts varyuig from broad-lanceolate to Unear, often toothed. Fruit smaller 

 than in the broad S., the ribs less prominent, the vittas less superficial, the 

 calyx-teeth very minute. 



in wet ditches, and shallow streams, throughout temperate and southern 

 Europe and western Asia, from south Sweden to Persia. In Britain, rather 

 more common than the broad S. in the greater part of England and Ire- 

 land, but becoming scarce in nortliern England and southern Scotland. 

 7^/. summer. 



XIV. FIMPIVTEX.. PIMPINELLA. 



Leaves dissected. Umbels compound, without mvolueres. Petals broad, 

 notched with an inflected pomt. Fruit short, somewhat laterally com- 

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

 ribs, 2 or 3 vittas under each interstice, and several vittas on the inner face. 



The genus, as now usually limited, contains a considerable number of 

 species, chiefly from the Mediterranean region and west-central Asia. The 

 shape of the fruit is nearly that of Apium, but the ribs are much less promi- 

 nent, and the vittas more numerous.
