UMBELLIFERAE (PARSLEY FAMILY) 



2. P. Nuttallii (DC.) Britton. Similar in habit ; involucral bracts short and 

 entire ; fruit only 1 mm, long, as broad as high, blunt. (^Discopleura DC.) — 



111. to e. Kan., La., and Tex. 



11. AEG0P6dIUM L. Goutweed 



Fruit ovate, glabrous, with equal filiform ribs, and no 

 oil-tubes ; stylopodium conical and prominent ; seed nearly 

 terete. — A coarse glabrous perennial, with creeping root- 

 stock, sharply toothed ovate leaflets, and rather large naked 

 umbels of white flowers. (Name from at^, goat, and 7r68iov, 

 a little foot, probably from the shape of the leaflets. ) 



1. A. PodagrAria L. — Waste-heaps, etc., e. Mass. to Del. 

 (Adv. from Eu.) Fig. 824. 



12. CICtTTA L. Water Hemlock 



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

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

 stylopodium depressed ; seed nearly terete. — Very poisonous 

 plants, with pinnately compound leaves and serrate leaflets, in- 

 volucre usually none, involucels of several slender bractlets, and 

 w^hite flowers. (The ancient Latin name of the Hemlock.) 



1. C. maculata L. (Spotted Cowbane, Musquash Root, 

 Beaver Poison.) Stem stout, 1-2.2 m. high, streaked with 

 purple ; leaves 2-3-pinnate, the lower on long petioles ; leaflets 

 lanceolate to oblong-lanceolate, 3-12 cm. long, acuminate ; pedicels 

 in the umbellets numerous, very unequal ; fruit broadly ovate to 

 oval, 3-3.5 mm. long, shallowly or not at all grooved at the com- 

 missure. — N. B. to Va., and westw., common. Fig. 825. 



2. C. Curtissii Coult. & Rose. Coarser ; fruit 2-3 mm. long, 

 subglobose, grooved at the junction of the carpels. — Ya. to Ky., 

 and southw. — Perhaps only a variety of the preceding. 



3. C. bulbifera L. Eather slender, 3-10 dm. 

 high ; leaves 2-3-pinnate (sometimes appearing ternate) ; leaflets 

 linear, sparsely toothed, 2-5 cm. long ; upper axils bearing clus- 

 tered bulblets; fruit (rare) scarcely 2 mm. long. — Common in 

 swamps, N. S. to Md. and Ida. 



13. CARUM L. Caraway 



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

 conspicuous ribs ; oil-tubes solitary ; stylopodium conical ; seed- 

 face plane or nearly so. — Smooth erect slender herbs, with fusi- 

 form or tuberous roots, pinnate leaves, involucre and involucels 

 of few to many bracts, and white (rarely pink) flowers. (Name 

 perhaps from the country, Caria.') 



1. C. Carvi L. (Caraw^ay.) Leaves with filiform divisions. 

 — Naturalized in many places, especially northward. (Nat. from 

 Eu.) Fig. 826. 



82.5. C. macu- 

 lata X 4. 



14. PETROSELtNUM Hoffm. Parsley 



Calyx-teeth obsolete. Petals greenish-yellow, with attenuate incurved points. 

 Fruit ovate, glabrous, laterally compressed ; carpels pentagonal, the primary 

 ribs filiform, subequal ; oil-tubes solitary in the intervals ; stylopodium cushion- 

 like. — Chiefly biennials, with ternately pinnate decompound leaves, toothed 

 leaf-segments, compound umbels, few-parted involucres, and several-many- 

 parted involucels. (Name from w^rpa, a rock, and <t^\lvov, paisley.)
