12. APIUM L. 



Ours erect glabrous biennial with fibrous roots and pinnately divided leaves. 

 Stems tri- or di-chotomously branched, forming a paniculate inflorescence, the 

 compound umbels terminal on the branches and subsessile in the forks. In- 

 volucre and involucels small or none, or the former sometimes foliaceous. 

 Flowers white, in compound umbels. Calyx-teeth obsolete. Fruit elliptic-ovate 

 or broader than long. Ribs prominent, obtuse, equal. Oil-tubes solitary in the 

 intervals, 2 on the face. Seed-face plane. (Old Latin name of Celery.) 



1. A. graveolens L. Common Celery. Erect, 3 or 4 ft. high; lower leaves 

 long-petioled, leaflets 5 (or 7 or 9), l 1 /^ to 3 in. long and as broad or broader, 

 coarsely toothed and 3-cleft or even -divided; upper leaves on short petioles or 

 sessile, the leaflets 3 ; rays 4 to 12 lines long ; fruit % to % line long. 



An escape from gardens; naturalized in the marshes from Suisun to Mon- 

 terey. July-Aug. 



13. CICUTA L. Water Hemlock. 



Tall branching glabrous perennials growing in marshes or by stream banks. 

 Rootstocks short and erect, or horizontal and branching. Leaves pinnately or 

 ternately compound. Flowers white, in compound umbels. Calyx-teeth some- 

 what prominent. Involucre present or none. Involucels of small bractlets. 

 Fruit oblong to orbicular, glabrous. Ribs corky, broad but low, the lateral in 

 cross section evidently larger than the intermediate and dorsal. Oil-tubes 2 on 

 the face, solitary in the intervals. (Classical name of the Hemlock, which was 

 given to criminals, and sometimes, when the Greeks had a superfluity, to phil- 

 osophers, as a death-poison.) 



Involucre none or of a single bract; fruit 1 to 1^ lines long; hill streams. ... 1. C. virosa. 

 Involucre of several to many lanceolate bracts; fruit nearly 2 lines long; salt marshes....
