20H UMBELLIFERjE. (PARSLEY FAMILY.) 



1. Z. lliirea, Koch. Leaves (except the uppermost) 2- 3-ternate, the radi- 

 cal very long-petioled ; leaflets ovate to lanceolate, sharply serrate ; ravs 1 5 - 

 25, stout (1 - 2' long) ; fruit oblong, about 2" long. (Thaspium aureum, var. 

 apterum, Gray, Manual.) Atlantic States, west to Minn, and Tex. 



Var. Bebbii, Coult. & Rose. A more slender mountain form, with leaf- 

 lets more coarsely serrate, the radical leaves smaller and more simple; rays 

 2-8, slender (2-3' long) ; fruit oval, 1 - 1" long. W. Va. and Va. to Ga. 



2. Z. COrdata, DC. Radical leaves mostly long-petioled, cordate or even 

 rounder, crenately toothed, very rarely lobed or divided ; stem-leaves simply ter- 

 nate or quinate, with the ovate or lanceolate leaflets serrate, incised, or some- 

 times parted ; fruit ovate, 1-J-" long. (Thaspium trifoliatum, var. apterum, Gray, 

 Manual.) Same range as the preceding, but extending farther westward. 



25. CARUM, L. CARAWAY. 



Calyx-teeth small. Fruit ovate or oblong, glabrous, with filiform or incon- 

 spicuous ribs ; oil-tubes solitary ; stylopodium conical ; seed-face plane or nearly 

 so. Smooth erect slender herbs, with fusiform or tuberous roots, pinnate 

 leaves, involucre and involucels of few to many bracts, aud white (or yellow- 

 ish) flowers. (Name perhaps from the country, Caria.) 



C. CARUI, L. (CARAWAY.) Leaves pinnately compound, with filiform di- 

 visions. Naturalized in many places, especially northward. (Nat. from Eu.) 



C. PETROSELINUM, Benth., the common PARSLEY, from Europe, with 3- 

 pinuate leaves, ovate 3-cleft leaflets, and greenish yellow flowers, is occasion- 

 ally found as an escape from cultivation. (Petroseiiuum sativum, Hojf'in.) 



26. C I CUT A, L. WATER-HEMLOCK. 



Calyx-teeth prominent. Fruit oblong to nearly orbicular, glabrous, with 

 strong flattish corky ribs (the lateral largest) ; oil-tubes conspicuous, solitary ; 

 stylopodium depressed ; seed nearly terete. Smooth marsh perennials, very 

 poisonous, with pinnately compound leaves aud serrate leaflets, involucre usu- 

 ally none, involucels of several slender bractlets, aud white flowers. (The 

 ancient Latin name of the Hemlock.) 



1. C. maculata, L. (SPOTTED COWBANE MUSQUASH ROOT. BEAVER- 

 POISON.) Stem stout, 2-6 high, streaked with purple; leaves 2-3-pinnate, 

 the lower on long petioles ; leaflets lanceolate to oblong-lanceolate (1 - 5' long), 

 acuminate, coarsely serrate, the veins passing to the notches ; pedicels iu the 

 umbellets numerous, very unequal; fruit broadly ovate to oval, l-l^" long. 

 Throughout the U. S. Aug. 



2. C. bulbifera, L. Rather slender, 1-3 high; leaves 2-3-pinnate 

 (sometimes appearing ternate) ; leaflets linear, sparsely toothed (1-2' long); 

 upper axils bearing clustered bulblets ; fruit (rare) scarcely 1" long.- Common 

 in swamps, N. Scotia to Del., west to Minn, and Iowa. 



27. .2E GO PODIUM, L. GOUTWEED.. 



Calyx-teeth obsolete. Fruit ovate, glabrous, with equal filiform ribs, and 

 no oil-tubes; stylopodium conical and prominent; seed nearly terete. A 

 coarse glabrous perennial, with creeping rootstock, biternate leaves, sharply 

 toothed ovate leaflets, and rather large naked umbels of white flowers. (Name 

 from a?, goat, and ir65iov, a little foot, probably from the shape of the leaflets.) 



.33. PODAGRARIA, L., a common and troublesome weed in Europe, is re- 

 ported from R. I. to Del. and E. Penn.
