290 Umbelliferae 



3. Ij. dasycarpum (T. &G.) C. & R. Very short, caulescent 

 or acaulescent, with several stout peduncles, 1.5-3 cm. long, from 

 a common root, tomentose-pubescent ; leaves rather small, pin- 

 nately decompound, with numerous short linear segments ; umbel 

 somewhat equally 6-15-rayed ; bractlets linear to ovate, more or 

 less tomentose; rays 2.5-7.5 cm. long; pedicels 6-10 mm. long; 

 flowers white ; fruit nearly orbicular, coarsely pubescent, becom- 

 ing almost glabrous, 8-14 mm. long, 7-12 mm. broad, with thin 

 membranous wings, broader than the body, and filiform dorsal and 

 intermediate ribs ; oil-tubes large and solitary in the intervals (an 

 occasional secondary one in the lateral intervals) , 4 on the commis- 

 sural side ; seed deeply sulcate beneath the oil-tubes, with plane 

 face. 



Occasional on dry hillsides, especially in the interior region. 



20. EUBYPTEBA Nutt. 



Acaulescent or caulescent glabrous perennials, with 

 elongated roots, branching only from the base, leaves 

 once or twice compound, with usually broad sharply 

 toothed leaflets. Flowers yellow. Calyx-teeth minute 

 or obsolete. Fruit strongly flattened dorsally, orbicular 

 to shortly oblong. Carpel with filiform ribs, and with 

 broadly winged laterals, these often distinct at base 

 and becoming cordate or emarginate, cohering until 

 maturity with those of the other carpel ; pericarp thin. 

 Stylopodium wanting ; disk impressed. Oil-tubes 1-sev- 

 eral in the intervals. Seed strongly dorsally flattened, 

 with plane face. 



1. E. lucida Nutt. Short, caulescent, glabrous, rather stout, 

 1.5-5 dm. high; leaves ternate; leaflets broadly cordate, some- 

 what lobed, coarsely mucronate-toothed, 1-2.5 cm. long; umbel 

 equally 8-15-rayed ; bractlets lanceolate ; rays 1-5 cm. long ; pedi- 

 cels 12 mm. long; fruit nearly orbicular, emarginate at each end, 

 glabrous, 10-14 mm. in diameter, with wings more than twice as 

 broad as the body, and prominent dorsal and intermediate ribs; 

 oil-tubes solitary in the intervals, 2-4 on the commissural side. 

 Occasional on dry ground in the chaparral belt in all our mountains.
