 is place. In typical Ferula communis, as it first became known 

 dna as it occurs commonly in Southern Europe, the ultimate leaf 

 segments are generally over 2 cm., and frequently over 3 (up to 

 «) cm. long, with a width of 1 mm. or less. Occasionally, how-

less than 1 (to 0-5) cm. in length, and 05-1 mm. in width. Such 

 specimens were described in 1820 from Portugal as Ferula breri- 

 jotia by Link in Roemer and Schultes' Systema (vol. VI., p. 592),
