UMBELLIFERiE. 



Leaflets y z to % in. long; bractlets inconspicuous, shorter than the umbellet; 



fruit 2 lines long or less, with filiform ribs 1. V. Kelloggii. 



Leaflets 1 in. long or more; bractlets conspicuous, some exceeding the 



umbellet; fruit 3 to 4 lines long, with prominent sharp ribs 



2. V. Hartwegi. 



1. V. Kelloggii (Gray) C. & K. Minutely scabrous, f to If ft. 

 high; flowering stems leafless or with a single leaf \ to 1 ft. above the 

 base; leaves 1 to 2 or 3 times ternate; leaflets ovate or roundish, 

 sharply serrate, incised, the terminal divisions ternate, or quinate, or 

 divided, mostly J to 1 in. long; rays about If in. long, in fruit 3| in. 

 long or less; pedicels 1 to 2 lines long; bractlets inconspicuous, 

 shorter than the umbellets; fruit 1 to 2 lines long, nearly as broad; 

 ribs filiform; oil-tubes 3 in the dorsal intervals, 5 to 6 in the laterals, 

 8 to 10 on the commissural side. — (Deweya Kelloggii Gray.) 



Rather rare: Mission Hills, San Francisco, Bolander acc. to Gray; 

 Mt. Tamalpais, Jepson; Bolinas Bay, Kellogg, who first collected it; 

 Petaluma, fide Coulter & Kose; Monterey Co., Eastwood; Fort 

 Tejon acc. to Coville. A more slender plant than the next.

 penetrates vertically to a depth of 2 ft. or more and is f to 1 in. in

 divided, or a portion triternately divided, the ultimate lateral divi- 

 sions mostly 3-foliolate, the ultimate middle divisions mostly

 nate, nearly 1 to 2 in. long, or the leaflets often more or less confluent; 



etioles 2 to 6 in. long; rays about 15, 2 in. long or less; bracts none; 



ractlets 3 to 6, unequal, linear-lanceolate, long-pointed, exteriorly 

 disposed, mostly surpassing the umbellets; flowering pedicels less 

 than 1 line long; fruit nearly orbicular, smooth, 3 to 4 lines long; 

 ribs filiform; oil-tubes as in the last. — (Deweya Hartwegi Gray.) 



Higher slopes in the hills, somewhat rare in our district: Mt. 

 Diablo; Niles; Oakland Hills; San Luis Obispo Co.; Sierra Foothills, 

 Upper Sacramento Valley, where first collected by Hartweg in 1847; 

 Folsom; Amador Co.; Mariposa Co.; Sequoia Mills; Kern Co.

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. Involucre 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 commissural side. Seed-face plane. [Old 

 Latin name of Celery.) 



1. A. graveolens L. Common Celkry. Erect, 3 or 4 ft. high; 

 lower leaves long-petioled, leaflets 5 (or 7 or 9), to 3 in. long and 

 as broad or broader, coarsely toothed and 3-cleft or even -divided;
