 white flowers. Involucre commonly none; involucels of numerous bracts. Calyx- 

 teeth obsolete or minute. Stylopodium conic or depressed. Fruit linear in our 

 species, beaked, laterally compressed. Carpels nearly terete, ribless except at 

 the beak; oil-tubes none. Seed-face channeled. [Greek name of this or some 

 allied plant.] About 10 species, natives of the Old World.

 rARSLEY. (I. F. f. 2676.) Annual, glabrous, or finely pubescent above, 4-6 dm.

 nately decompound into small segments; umbels 3-6-rayed, the rays divergent, 

 1-4 cm. long in fruit; pedicels stout, 4-6 mm. long; bracts of the involucels linear- 

 lanceolate, acuminate, about 2 mm. long; fruit 6 mm. long, glabrous and ribless, 

 tipped with a ribbed beak of one-third its length. Eastern and southern Penn. 

 Nat. from Europe. May-June. 



Anthriscus sylvt<stris (L.) Hoffm. Wild Beaked-parsley, a tall annual with 

 glabrous beakless fruit, has been found as a waif on Staten Island, and in ballast about

Anthriscus Anthrfscus (L.) Karst. Bur-chervil, readily recognized by its short- 

 beaked muricate fruit, has been found as a waif in N. S., according to Macoun.
