194 UMBKLLIFER^. (PAUSLEY FAMILY.) 



15. LIGUSTICUM, L. Lovage. 



Calyx-tccth small or iniimtc. Fruit elliptical, round on the cross-section, or 

 sliylitly flattened on the sides; the carpels each with 5 sharp and projcctinj,' or 

 narrowly winged ridjifes: intervals and inner face with many oil-tubes. — Peren- 

 nials, with aromatic roots and fruit, 2 - 3-ternately compound leaves, and white 

 flowers. (Named from the country IJguiia, where the oflicinal Lovage of the 

 gardens, L. /^vi.sticum, abounds.) 



1. L. Sc6ticum, L. (Scotch Lovage.) Very smooth; stem (2° high), 

 simple; Uuvcs 2-tcniiite ; leaflets rhombic-ovate, coarsely toothed or cut; leaflets 

 of the involucre and involuccls linear ; calyx-teeth distinct ; fruit narrowly oblong. 



r Salt marshes, from Kliode Island northward. Aug. — (Eu.) 



2. L. actseifblium, Michx. (Noxdo. Angelico.) Smooth; stem (3°- 

 6° high) branched above; the numerous umbels forming a loose and naked 

 somewhat whorkd panicle, the lateral ones mostly barren ; leaves 3-ternate ; leaf- 

 lets broadly ovate, equally serrate, the end ones often 3-partcd ; calyx-teeth mi- 

 nute ; ribs of the short fruit wing-like. — Rich woods, Virginia, Kentucky, and 

 southward along the mountains. July, Aug. — Root large, with the strong 

 aromatic odor and taste of Angelica. (Michaux's habitat, "Banks of the St. 

 Lawrence," is probably a mistake.) 



16. THASPIUM, Nutt. Meadow-Parsnip. 



Calyx-tccth obsolete or short. Fruit ovoid or oblong, somewhat flatfish or 

 contracted at the sides (the cross-section of each seed orbicular and somewhat 

 angled or 5-angular) ; the carpels each with 5 strong and equal ribs or wings, 

 the lateral ones marginal: oil-tubes single in each mterval. — Perennial herbs, 

 with 1 - 2-tcrnately divided leaves (or the root-leaves simple), umbels with no 

 involucre, minute few-leaved involuccls, and jellow or sometimes dark-purple 

 flowers. (Name a play upon Tliapsia, a genus so called from the island of Thap- 

 sus.) I include in this genus Zizia, Koch, — because the same species has fruit 

 either ribbed or winged, — and retain the name of Zizia for Z. integerrlma, DC. 

 * Stems looKfli/ branched, 2° -5° high, mosthj pubescent on the joints: calyx short but 

 mnnifest: corolla light yellow: leaves all ternately compound. 



1. T. barbinbde, Nutt. Leaves l-3-tcrnate; leaflets ovate or lance-ovate 

 and acute, mostly with a ivedge-shaped base, above deeply cut-serrate, often 2-3-cleft 

 or parted, the terminal one long-stalked (l'-2' long) ; fruit oblong, 6-\0-winged 

 (3" long), some of the dorsal wings often narrow or obsolete. — River-banks, 

 W. Now York to Wisconsin, and southward. July. 



2. T. pinnatifidum, Gray. Branchlets, umbels, &c. roughish-puberulent ; 

 leaves 1-3-ternatc; Uaflits 1 -2-pinnatifid, the lobes linear or oblong ; fruit oblong, 

 narrowly 8-lO-winged (1^' long), the intervals minutely scabrous. (Zizia pin- 

 natifida, Buckley. Thaspium Walteri, Shutllew., cxcl. syn. Walt.) — Barrens of 

 Kentucky (Short), and southward in the mountains. 



« « Stems somewhat branched ; tlie whole plant glabrous : calyx -teeth obscure. 



3. T. atireum, Nutt. Leaves all l- 2-lernat<ly divided or parted (or i-Mdy 

 Bome of the root-leaves simple and heart-shaped) ; the divisions or leaflets oblong-
