354 UMBELLIFEE^. 



Leaves pinnately compound. Flowers white in compound umbels, 

 terminating the branches. Involucre present or none. Involucels 

 present. Oalyx-teeth rather prominent. Styles slender, at length 

 elongated. Fruit globose-ovate, cylindric or slightly flattened later- 

 ally. Eibs broad, obtuse, corky; commissural face also corky. Oil- 

 tubes solitary in the intervals, 2 on the face, the seed furrowed beneath 

 them. (Ancient Greek name of some thorny plant.) 



Fruit subcylindric, 2 lines long . 1. ffi. Californica. 



Fruit ovate-globose, 1 line long . . . . .2.CE. sarmentosa. 



1. CE. Californica Wats. Erect, 2 to 4 ft. high; leaves bipinnate; 

 leaflets elliptic-ovate in outline, 3-cleft or -parted and also coarsely 

 toothed or incised, those of the upper leaves crowded on the rachis 

 and sometimes tending to be conduplicate; rays less than 1 to 2 in. 

 long; bracts few or none; bractlets several to many, lanceolate and 

 shorter than the pedicels; fruit cylindric, 2 lines long, crowded. 



Usually in dense masses on the margins of slow streams and shallow 

 pools or ponds; common in the Coast Ranges. In autumn the sum- 

 mits of the stems maj' give rise to very slender runner-like branches 

 3 to 5 ft. long, which produce at intervals bulblets J in. in diameter 

 or less. June. Fruiting Aug.-Sept. A specimen from the Coyote 

 Hills, Alameda Co., has many linear-spatulate bractlets much sur- 

 passing the umbellets and corrimbnly serrulate at apex. 



2. CE. sarmentosa Presl. Three or 4 ft. high; leaves simply 

 pinnate; leaflets 5 to 13, 6 in. long or less, ovate-lanceolate, the lower 

 obliquely lobed on the lower side or with an almost distinct supple- 

 mentary leaflet; rays 1 to 2 in. long; bracts few or none; bractlets 

 lanceolate, acuminate; fruit subglobose or somewhat ovatish, 1 line 

 long, the corky ribs somewhat turgid. 



Carmel Kiver, Monterey Co., and northward along the coast; rare 

 with us. 



20. BERULA Hoffm. 



Glabrous marsh perennial with pinna'te leaves and serrate leaflets. 

 Flowers white, in terminal compound umbels. Bracts narrow. 

 Bractlets unequal, 1 or 2 surpassing the flowers. Fruit subglobose, 

 glabrous, surrounded by a continuous corky covei'ing of confluent 

 ribs. Oil-tubes numerous and contiguous, in the mature fruit more 

 or less confluent, closely surrounding the seed cavity. (Latin name 

 of the Water-cress.) 



1. B. erecta (Huds.) Coville. Water Parsnip. Erect, corym- 

 bosely branching above, 8 ft. high; leaves simply pinnate; leaflets 9 

 to 19, 1 or 2 in. long, ovate to linear, serrate or laciniately lobed; 

 umbels many-rayed; rays J to 2 in. long in fruit; pedicels 2 to 8 lines 

 long; fruit less than 1 line long. — (Slum angustifolium L.)
