Glaucous; st. low flexuose repeatedly fork-branched from the 
base, branches straggling widely divaricate spreading ; 1. mostly 
heterophyllous, lower or root-1, pinnate or subbipinnate with 
leaflike simple oblong-obovate or spathulate sharply finely and 
evenly cartilaginously mucronate and serrulate lfts. ; upper 1. 
always decompound or finely multifid 2-3-pinnatisect with flat 
narrow-lanceolate or linear-lanceolate regularly serrate or entire 
segments, each ultimate tooth or segm. ending in a fine cartila- 
ginous awn or point ; umbels opposite the 1. moderately stalked 
10-30 -rayed, the rays (gen. and partial) finely scabrous spread- 
ing, erect or subincurved infr. ; gen. inv. several distinctly shorter 
than the rays , mostly about half as long, setaceo-pinnatifid or 
trifid, partial numerous simple linear with membranous margins 
and produced into fine setaceous awn-like points. — Herb, ann., 
Mad., PS., GD. reg. 1, 2. Apr. -Aug. — From 6 to 18 in. rarely 
2 ft. high stragglingly branched throughout, but though low 
neither bushy nor with a distinct erect straight main stem de- 
veloped at the expense of the shortened or partially suppressed 
side branches. Whole pi. altogether smooth and more or less 
(especially the broad imclivided lower lfts. in a. and y.) glaucous, 
almost or quite scentless and tasteless. St. branched flexuose 
or zigzagged from the base, regularly and widely forked, pale 
and whitish with narrow gr. lines or striae downwards, slender 
but hard and stifl', round smooth and even or only angular and 
faintly ribbed upwards. Lfts. of the root and lower st.-l. mostly 
but not always undivided and leaf-like, and then somewhat stifl’ 
and coriaceous shining 2-4 times as long as broad finely and 
closely cartilagineo-serrate ; of the upper 1. gradually narrower 
and more lanceolate with the margins either gashed and re- 
gularly serrate or entire : but sometimes all the 1. are finely 
decompound and 2-3-pinnatisect with narrow linear-lanceolate 
segments which are either serrate or entire. — Umbels confluent 
of moderate size or rather small, their stalks 2-3' in. long round 
striate smooth and even, with from 8 or 10 to 20 or 30 equal 
slender minutely subscabrous rays spreading in fl., suberect in 
ff. ; partial ravs very numerous unequal scabrous especially up- 
wards, spreading in fl., suberect in fr. Fl. rather large pure w. 
all fertile with large pet.; ovary subpuberulously scabrous; styles 
divergent a little longer than the distinct convex presently coni- 
cal conspicuous stylopod, deflexed in fr. Gen. inv. about 0 short, 
never exceeding -h or | the length of the rays, simple or com- 
pound with fine almost setaceous divisions, and either trifidly 
linnate or ending in a trifid segment, each segm. finely carti- 
agineo-cuspidate; the whole quite smooth and even. Involucels 
simple and subscabrous numerous linear-lanceolate with broad
