1. L. lucidum (Nutt.) Jepson. Plants 1.4 to 4.3 dm. high, the stout 
peduncles from very short stems; leaves once or twice ternate; leaflets 
roundish to ovate, toothed; rays 2.4 to 7.2 cm. long; bractlets lanceolate; 
oil-tubes solitary in the intervals.—Coastal S. Cal. 
2. L. caruifolium (T. & G.) C. & R. Stem almost.none, the peduncles 
three or four, 2 to 3 dm. high; leaves ternately dissected into small linear 
segments, finely hispid; fruiting rays 2.4 to 3.6 cm. long; bracts none; 
bractlets several; wings of fruit half to almost as wide as bod'*; oil- 
tubes none or indistinct.—Low subsaline soils. 
3. L. utriculaturn (T. & G.) C. & R. Bladder Parsnip. Plants 2.4 to 
3.8 dm. high, the proper stems short; leaves triternately dissected into 
small linear segments; fruiting rays 2.4 to 7.2 cm. long; bracts 1 to 3; 
bractlets several, scarious-margined; wings scarcely as wide as body 
of fruit; oil-tubes mostly solitary in the intervals.—Common on open 
hillsides. 
4. L. macrocarpum (Nutt.) C. & R. Plants 2.8 to 4.3 dm. high, the 
stems several from a stout tap root; leaves twice ternate and twice pin- 
nately divided, the ultimate segments linear, 2 to 6 mm. long and about 
1 mm. wide; ultimate divisions of rachis winged; fruiting pays 3.6 to 
4.8 cm. long; fruit glabrous, 12 to 16 mm. long, 4 to 8 mm. broad; 
oil-tubes solitary in the intervals.—Dry hillsides. 
5. L. dasycarpum (T. & G.) C. & R. Plants 3 to 4.3 dm. high, the 
peduncles arising from the root-crown or from very short stems; leaves 
triternately decompound and dissected into linear or oblong segments, 
these 2 to 4 (or 6) mm. long; rays 2.4 to 4.8 cm. long; bractlets "linear to 
ovate; fruit broadly elliptic to orbicular, 7 to 8 (or 14) mm. long, the 
thin wings 2 to 3 times the width of the body; oil-tubes usually 1 (rarely 
2) in the intervals.—Coastal S. Cal. and n. in the Coast Ranges. 
6. L. nudicaule (Pursh.) C. & R. Pestle Parsnip. Plants 1.9 to 4.8 
dm. high; leaves once or twice ternate, then pinnate; leaflets broadly 
ovate to lanceolate, entire; rays very unequal; fruit oblong to elliptic, 
wings half as wide as the body; oil-tubes 1 or 2 in the intervals.—Low 
open foothills and rolling plains. 
17. PASTINACA L. 
Tall branching biennial with angular stems from thick roots. Leaves 
large, simply pinnate. Flowers yellow, in compound umbels. Bracts 
and bractlets small or none. Fruit oval, compressed. Lateral ribs 
winged, the others filiform. Oil-tubes solitary in the intervals. (Latin 
name of the parsnip.)
