The order Umbelliferce has been lately remodelled by 

 Professor Sprengel, in a monograph which we believe is not 

 yet published; but which has been communicated to 

 Messi-s. Roemer and Schulte, by whom the substance is em- 

 bodied in the sixth volume of their edition of the " Systema 

 Vegetabilium." 



Peucedanum ranks in the tribe Selinece, distinguished 

 by compressed, flat, frequently winged fruit, and variable 

 involucres. Its generic character is founded on " the flat 

 .marginated wingless fruit, with either three or five obtuse 

 dorsal ribs (costse) vertically scored by sunk lines and a 

 parallel suture." 



The present species is native of the Canary Islands, from 

 whence it was introduced by Mr. Francis Masson in 1790. 



The drawing was taken from a sample which flowered in 

 Mr. Lambert's garden, at Boyton, in Wiltshire.
