11G ENGLISH BOTANV. 



Sub-Genus II.— ABCIIANGELICA. Eoffim. 



Calyx-limb of 5 small teeth. Mericarps plano-convex, with the 

 dorsal and intermediate pair of ridges thick, keeled, the lateral 

 pair produced into thin somewhat corky wings ; interstices without 

 vitta;. Seed free from the pericarp, with numerous vittce.

Stem erect, hollow, smooth helow. Leaves ternately bipinnate ; 

 leaflets ovate, sometimes slightly lobed, serrate; petioles of the 

 upper leaves dilated into very large sheaths. Involucre of 1 to 3 

 caducous leaves. Mowers greenish-white. Calyx-limb of 5 small 

 teeth. Wings of the mericarps never scarious, somewhat corky 

 when mature, those of the opposite mericarps almost contiguous. 



In wet places, by the sides of streams. Very rare, and not 

 native. It is said to have occurred near Bury St. Edmunds, Suffolk ; 

 at Broadmore, seven miles north-west of Birmingham ; on the banks 

 of the Skern, Durham; and formerly about Battersca Fields, and 

 by the side of the Thames between Woolwich and Plumstead. I 

 found a few specimens about ten or twelve years ago between 

 Greenwich and Woolwich, close to high- water mark. I also onco 

 saw it on Eiskerow Links, near Edinburgh ; but as the rubbish 

 from adjoining gardens was cast there, no doubt the plant came 

 with it, and as I failed to find it in succeeding years, it cannot be 

 considered even a naturalized Scotch plant. 



[England.] Perennial or Biennial ? Summer 

 and Autumn. 



This plant, when in flower, is so extremely like A. sylvestris that 

 it can only be distinguished by the presence of the calyx-teeth, the 

 green tinge of the flowers, and the more numerous rays of the 

 umbel : when in fruit, however, the cremocarp is very different, 

 being convex on each side and nut flattened, shorter (\ inch long), 

 and broader in proportion, with the ridges much thicker and more 

 prominent, the lateral ones corky, and not membranous in any 

 stage ; besides this, the lateral wings of the 2 mericarps are almost 

 contiguous, so that the fruit can scarcely be said to be surrounded 

 by a double wing, as in the true Angelica*, so that this plant makes
