UMBELLIFEE/E. 



835 



long sheathing footstalk, pinnate, with 

 several pairs of segments, which are 

 sessile, but once or twice pinnate, with 

 short linear lobes ; in a leaf of 3 or 4 

 inches, the lowest or next to the lowest 

 segments are ' about f of an inch long, 

 the others diminishing gradually to the 

 top. Upper leaves smaller and less di- 

 vided. Umbels of about 8 or 10 rays, 

 either without involucres or with 1 or 

 2 small linear bracts. Carpels (com- 

 monly called Car aw ay -seeds) about 2 

 lines long, linear-oblong, and usually 

 curved, with the ribs prominent. 



In meadows, and moist pastures, in 

 the greater part of Europe and Rus- 

 sian and central Asia, from the Arctic 

 regions to the Mediterranean and Hi- 

 malaya, more rare in western Europe. 

 Occurs in many parts of Britain ; if not 

 truly indigenous, at any rate well naturalized, having been long cul- 

 tivated for its aromatic carpels. Fl. spring and early summer.

3. Tuberous Carum. Carum Bulbocastanum, Koch. 

 (Fig. 407.) 

 (Bunium, Eng. Bot. t. 1524, Suppl. t. 2862.) 

 Resembles the tuberous JBunium, and, 

 like that species, the stock forms globu- 

 lar, underground tubers, known by the 

 name of JSarthnuts or Pignuts. Radical 

 leaves (which usually disappear at the 

 time of flowering) twice or three times 

 ternate ; the segments all stalked and 

 pinnately divided into a small number of 

 linear lobes, less unequal than in the 

 tuberous JBunium. Involucres always 

 present, consisting of a few very fine 

 bracts. Carpels like those of the Cara- 

 way, but more slender, with the ribs 

 rather less prominent, although more so 

 than in the tuberous Bunium, and the 

 face of the seed is flat or slightly con- 

 cave, not furrowed as in the Bunium. 

 Vittas single under each interstice. Fig. 407.
