RYDBERG: Rocky MOUNTAIN FLORA 575 
dead leaves ; leaves once or twice pinnate, dark green, glabrous, 
stiff and shining, 1-2 dm. long ; petioles about equaling the 
blades, striate ; leaf-segments obovate to rhombic-cuneate, deeply 
cleft; lobes usually 3-toothed with lanceolate acuminate teeth ; 
scapes I-1.5 dm. long; involucres lacking; branches of the 
umbel very unequal, in fruit 1-5 cm. long; bractlets linear-sub- 
ulate, 4~5 mm. long ; pedicels also very unequal, in fruit 1-8 mm. 
long ; sepals conspicuous, in fruit 1-2 mm. long; flowers yellow ; 
fruit 5~6 mm. long, 2.5—3 mm. wide ; lateral wings evident but 
rather narrow ; dorsal ribs acute or slightly winged; seed flat- 
tened and with somewhat concave face; oil-tubes usually solitary 
in the intervals, 
This species is evidently most closely related to P. amisatus, 
but easily distinguished by the very unequal branches of the 
umbel, the longer, usually less winged fruit and especially by the 
leaves, which (although much firmer) resemble closely those of 
Aletes acaulis, The plant evidently connects the two genera 
Aletes and Pseudocymopterus. The fruit of the present species is 
also intermediate between A. acaulis and P. anisatus, and were it 
not for the flatness of the seed and the lateral wings of the fruit, it 
might have been referred to Aletes. It grows in the mountains of 
Which Pike’s Peak is the center, at an altitude of 2,000—2,600 m.
