only as a section. Levisticitm also has simple vittse, like the true 

 Angelicas, and the marginal wings of the fruit are thicker. This 

 plant, with us will also form only a section Levisticum of the genus 

 Angelica, thus comprising perennial herbs from the temperate regions 

 of both worlds, with compound or decompound pinnate leaves, the 

 segments of which are large and the involucres formed of bracts 

 few in number, and but little developed, more numerous and narrow 

 in Levisticum, 



The other tran- 

 sition genera re- 

 ferred to are 

 Astydamia, Pole- 

 mannia, and Aci- 

 phylla. AstydU' 

 mia canariensis is 

 a perennial whose 

 fruit is that of 

 a Peuceclan, with 

 wide solitary vitt SB 

 in each furrow ; 

 but the mericarps 

 have thick sub- 

 erose margins 

 which early sepa- 

 rate from each 

 other. The car- 

 pophore unlines 

 itself at maturity, 

 and the vittae are 

 wide and solitary 

 in each furrow. 

 The seeds have a 

 flat or slightly 



concave surface. The embryo, with long lanceolate cotyledons, occupies 

 about half the length of the albumen. Polemannia consists of types 

 with small somewhat rounded fruit. The margin is thick and almost 

 fleshy, and the base of the mericarp is decurrent on the pedicel. 

 They are Cape shrubs whose full inflorescence bears simple lateral
