UMBELLIFERJE. (PABSLET FAMILY.) 155 



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

 flowers. (Named from the country Liguria, where the officinal Lovage of the 

 gardens, L. Levisticum, abounds.) 



1. It. Scdticum, L. (SCOTCH LOVAGE.) Very smooth; stem (2 

 high) nearly simple; leaves 2-ternate; leaflets rhombic-ovate, coarsely toothed 

 or cut; leaflets of the involucre and involucels linear; calyx-teeth distinct; 

 fruit narrowly oblong. Salt marshes, from Rhode Island northward. Aug 

 Boot acrid but aromatic. (Eu.) 



2. JL. actseifolium, Michx. (NONDO. ANGELICO.) Smooth; stem 

 (3 -6 high) branched above; the numerous umbels forming a loose and naked 

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

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

 minute ; 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. TIf ASPIUM, Nutt. MEADOW-PARSNIP. 



Calyx-teeth obsolete or short. Fruit ovoid or oblong, somewhat flattish 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 interval. Perennial herbs, 

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

 involucre, minute few-leaved involucels, and yellow or sometimes dark-purple 

 flowers. (Name a play upon Thapsia, a genus so called from the island of 

 Thapsus.) I include in this genus Zizia, Koch, because what is apparently 

 the same species has the fruit either ribbed or winged, and retain the name 

 of Zizia for Z. intcgerrima, DC. 



# Stems loosely branched, 2 - 5 high, mostly pubescent on the joints : calyx short but 

 manifest : corolla light yellow : leaves all ternately compound. 



1. T. barbindde, Nutt. Leaves 1- 3-ternate; leaflets ovate or lance- 

 ovate and acute, mostly with a wedge-shaped base, above deeply cut-serrate, often 

 2-3-cleft or parted, the terminal one long-stalked (l'-2'long) ; fruit oblong, 

 B-lO-winged (3" long), some of the dorsal wings often narrow or obsolete. 

 River-banks, W. New York to Wisconsin, and southward. July. 



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

 leaves 1 - 3-ternate ; leaflets 1 - 2-pinnatifld, the lobes linear or oblong ; fruit oblong, 

 narrowly 8-lQ-winged (!' long), the intervals minutely scabrous. (Zizia pin- 

 natifida, Buckley. Thaspium Walteri, Shuttlew., excl. syn. Walt.) Barrens 

 of Kentucky (Short), and southward in the mountains. 



* # Stems somewhat branched; the whole plant glabrous : calyx-teeth obscure. 



3. T. aiircum, Nutt. Leaves all 1 -2-ternately divided or parted (or rarely 

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

 lanceolate, very sharply cut-serrate, with a wedge-shaped entire base ; flowers deep 

 yellow ; fruit oblong-oval, with 10 winged ridges. Moist rivei -banks, &c., not 

 rare. June. Leaves of a rather-firm texture.
