UMBELLIFEB^. 121 



Sisarwn ' differs from this section only in the more or less considerable 

 development of the involucre.^ 



We refer also to this genus as simple sections : Muretia,^ which is 

 Asiatic, and has a short fruit of Pimpinella, stylopoda the union of 

 which forms a sort of dome, a fruit with nearly circular transverse 

 section and a seed with more or less concave face ;* Chamcesciadium,^ 

 Siberian plants whose compound umbels have the principal axis 

 short, so that the umbellules supported by long radii appear at first 

 sight as simple umbels ; the fruit is quite that of a Garum, with the 

 numerous vittae of Pimpinella, the stylopods are little developed ; 

 Panulia,^ whose fruit, analogous to that of the Caraway, often (but 

 not constantly) has more prominent ridges and numerous vittse ; it 

 inhabits Chili; Lereschia,'' a genus proposed for Gryptotcenia Thomasii,^ 

 a NeapoHtan species with small stylopods and loose irregular inflo- 

 rescence ; and Petvosciadium,^ Asiatic plants which, with the characters 

 of Tragium, Jiave in each furrow one, two, or rarely a larger number 

 of vittae. 



Thus understood," this great genus comprises about a hundred 

 and forty species," and belongs to all the temperate regions of both
