 Lanceolate, the former often scarious-margined; rays \y> in. long, subequal, 

 pedicels 2 lines long; fruit orbicular, 2 lines long, prominently ribbed, the 

 quite mature carpels rather strongly concave on the face, thus appearing

Erect branching glabrous biennial with slightly fusiform roots and dissected 

 decompound leaves. Flowers white in compound umbels. Bracts parted into 

 filiform segments. Bractlets lanceolate, acuminate. Flowers white, in a ter- 

 minal compound umbel with long rays and short pedicels. Calyx-teeth obsolete. 

 Fruit ovoid, very slightly flattened laterally. Ribs filiform. Oil-tubes solitary 

 in the intervals and 2 on the face. (Greek name of an umbelliferous plant.) 



1. A. majus L. Bishop's Weed. Stem slender, branching above, 1*4 

 to 2i/> ft. high; leaves triternately dissected into small spatulate segments (2 

 to 6 lines long), which are laciniate or serrulate at apex; rays about 25 to 

 30, little unequal, % to 2 in. long; pedicels 1 to 1% lines long; bracts linear 

 below, parted above into 3 filiform divisions; bractlets lanceolate, acuminate, 

 entire, scarious-margined at base; fruit less than 1 line long; carpels with 

 concave face; oil-tubes solitary in the intervals, 2 on the face. 



Low places in grain fields at Yountville and in marshes at Alvarado. 



15. CARUM L. 

 Ours erect and slender glabrous biennials or perennials. Leaves simply 

 pinnate with few linear entire leaflets. Flowers white, in compound umbels. 

 Involucre of entire bracts or none. Involucels of entire bractlets. Calyx-teeth 

 small. Stylopodium conical. Fruit ovate or oblong, laterally compressed, with 

 <>l>tiise ribs. Oil-tubes solitary in the intervals, 2 on the face. (Karon, Greek 

 Dame of the Caraway.) 



Stems clustered, from a fascicle of coarse roots; fruit 2 to 3 lines long....l. C. kelloggii. 

 Stem solitary, from a tuber or cluster of tubers; fruit about 1 line long... 2. C. gairdneri. 



1. C. kelloggii Gray. Stems several from a fascicle of coarse and hard 

 fibrous roots, it to 5 ft. high; radical leaves 5 to 10 in. long, ternate, each 

 <li\isi(in pinnate with narrowly lineal divisions 3 or 4 in. long; cauline loaves 

 similar bul smaller; Lnvolucral bracts and Lnvolucel bractlets several, lanceolate 

 or subulate; r;i\s :: , to 1 \ •_. in. long; stylopodium very large, with short stout 



styles; carpels frequently unequal or only one maturing. 



Very common in the open hill country about San Krancisco Hay: Vacaville;
