 of small linear bractlets; fruit oblong, 3 to 4 lines long; wings not undulate-crisped; intermediate 

 and dorsal wings sometimes reduced in breadth; oil-tubes 3 to 5 in the intervals, 6 on the com- 

 missure. — Northern Sierra Nevada, 1500 to 5000 feet, from Nevada Co. to Lassen Co.; inner

2. 0. panamintensis C. & R. Plants low (3 to 10 inches high) ; peduncles 

 purplish, arising from a root-crown sheathed with old leaf bases ; leaf -blades 2 

 to 2'% inches long, on petioles about as long, ternate, then once or twice pinnate, the 

 pinnae finely dissected ; ultimate segments 1 to II/2 lines long, tipped with a slender 

 bristle-like apiculation ; rays in fruit 1 to 1% inches long ; pedicels short ; involucre 

 none; involucels small, gamophyllous, somewhat one-sided, purplish, cleft into 

 ovate acuminate segments ; flowers greenish-yellow ; fruit 4I/2 lines long, glabrous, 

 each carpel with 5 broad wings, the wings very thick at insertion ; oil-tubes 3 or 4 

 in the intervals, 4 or 5 on the commissure ; seed face deeply concave. 



Dry rocky slopes, 3000 to 7000 feet : desert ranges of the eastern Mohave Desert 

 and Inyo Co. Apr., fr. May-June. 



Note on the fruit. — The fruit in horizontal cross section is an ellipse in outline, with the 

 long axis of the ellipse at right angles to the plane of the commissure. The fruit is thus tech- 

 nically a little obcompressed. Mature carpels are produced freely, yet the species is on the whole 

 rare in individuals.

 cuspidate or less obviously so. — Central Mohave Desert in the Mohave Eiver Valley (Eed 

 Knob, Barstow, Parish 19,235; Newberry, Hall 6127) and north side of the Colorado Desert

3. C. globosus Wats. Plants l^/o to 2i/^ inches high, the leaves basal or sub- 

 basal and the peduncles scape-like or nearly so ; herbage glabrous ; peduncles about 

 equaling the leaves ; leaf -blades ovate in outline, % to l^/^ inches long, pinnate, the 

 ovate segments pinnatifid and then incised or toothed ; petioles % to 2 inches long ; 

 umbels reduced to dense globose heads 10 to 13 lines wide in fruit ; sepals purplish, 

 narrowly lanceolate, over Yo as long as the petals ; petals whitish, broadly lanceo- 

 late, acuminate at tip ; wings on the ovary produced upward beyond the body and 

 acute ; fruits 31^ to 4% lines long; wings white, % to 1 line wide, a little aurieled 

 at base, conspicuously corky-thickened from the margin to the body of the fruit, so 

 that the outline in cross section is ovate, with the apex obtuse ; oil-tubes solitary 

 in the intervals, 2 on the commissure.
