120 NATURAL EI8T0RY OF PLANTS. 



and the stylopods rather more elongate. Atcenia ' and Edosmia ^ are 

 American Carums with a tuherous root or rhizome, the fruit of which, 

 with wide but not thick vittse often scarcely visible, in this respect 

 much resembles that of the Goutweeds.' 



The old genus Zizia,* from North America, is also one of those 

 which cannot be dismembered holding both to Pimpinella and to 

 Carum : to the latter by those species with sohtary vittse ; to the 

 former by Z. integerrima (Zizioides), whose vittse are numerous hke 

 those of Gryptotcenia,^ a perennial herb, of the same genus and from 

 the same country, with oblong fruit somewhat narrowed at the level 

 of the commissure. Many other types with geminate vittse or nearly 

 always in greater number, cannot be separated generically from 

 Pimpinella. Such are : Acronema,^ an annual of India with very thin 

 vittse ; Reutera,^ an annual or perennial herb of the Levant, differing 

 only in yellow petals entire or nearly so at the summit and convolute ; 

 Tragium,^ which, with white petals, has a fruit covered with hairs or 

 papillse,' like that of Trachyspermum ; Pituranthos ^^ or Deverra,^^ 

 having also a hairy fruit, but very thin solitary vittse ; Gymnosciadium,^^ 

 ah Abyssinian plant, having the characters of Tragiuvi, but with 

 glabrous fruit. 



Thereby this plant connects with the preceding sections Trago- 

 selinum,^^ perennial, rarely annual, species, with pinnate or decom- 

 pound leaves, sometimes undivided or simply dentate, of which 

 several, as P. Saxifraga, caruifolia and viagna, are common in Europe.
