Carrot Family 291 



2. E. Hassei C. & R. Caulescent, stout, 6 dm. high or more, 

 glabrous and somewhat glaucous, from a long slender woody 

 root; leaves biternate on very long petioles (sometimes 2.5 dm., 

 including petiole) ; leaflets broadly ovate with cuneate base, irreg- 

 ularly lobed, coarsely mucronate-toothed, 2. 5-10 cm. long, becom- 

 ing 6 cm. broad; umbel long-peduncled, equally 8-18-rayed; 

 bractlets varying from rather short linear-setaceous to oblanceo- 

 late, foliaceous, entire or toothed and much exceeding the pedi- 

 cels; rays 5-10 cm. long; pedicels 12-16 mm. long; fruit as in 

 the last. 



" Sierra Madre Canyon," ffasxe. We have seen no specimens that answer 

 the description of this plant, but forms of the last found in the Santa 

 Monica Mountains seem to approach it. No doubt it will be found to be only 

 a robust form of the last species. 



21. PASTINACA L. 



Tall erect mostly biennial branching herbs, with thick 

 roots, pinnate leaves, and compound umbels of yellow 

 flowers. Involucre and involucels commonly none. 

 Calyx-teeth obsolete. Stylopodium depressed. Fruit 

 oval, glabrous, much flattened dorsally ; dorsal and in- 

 termediate ribs filiform, the lateral winged, coherent 

 with those of the other carpel and forming a broad mar- 

 gin to the fruit. Oil-tubes solitary in the intervals, and 

 2-4 on the commissural side. Seed very flat. 



1. P. sativa L. Usually biennial, glabrous or somewhat 

 downy-pubescent, 6-15 dm. high; the root long conic, fleshy; 

 lower and basal leaves petioled, pinnate, often 4.5 dm. long; leaf- 

 lets rather thin, ovate or oval, obtuse, sessile, lobed or incised 

 and sharply dentate, 2-6 mm. long; upper leaves generally much 

 reduced ; umbels several or numerous, 5-15 cm. broad, 7-15-rayed ; 

 the rays slender, 1-5 cm. long; pedicels very slender, 6-12 mm. 

 long in fruit; fruit broad, the dorsal and intermediate ribs not 

 prominent, but the oil-tubes conspicuous. 



Rather frequent in marshes, especially toward the coast. 



22. DAUCUS L. 



Bristly annuals or biennials, with pinnately decom- 

 pound leaves, foliaceous and cleft involucral bracts,
