name of some plant of the Cruciferaceae.) W. E. 
L. communis L. 
CICHORIUM CHICORY 
Perennial (ours), erect; stem branched. Leaves entire to runcinate-pinnatifid in 
ours, largely basal; stem leaves usually small and bract-like. Heads 25—40 mm. wide 
(ours), sessile or peduncled, spike-like in arrangement (ours) ; involucre-bracts in 2 series, 
herbaceous; outer bracts somewhat spreading; inner bracts erect, subtending or partly en- 
closing the outer akenes; receptacle naked or minutely fringed. Corolla in ours white 
or blue.. Akenes 5-angled or -ribbed, truncate, not beaked. Pappus of 2—3 series of 
short blunt scales. (From its Egyptian name, chikouryeh.) W. 
C. intybus L. 
MICROSERIS 
Annual, acaulescent or with short stem 3 dm. or less high (ours). Leaves entire 
or laciniately lobed or pinnatifid. Heads small, nodding, on slender peduncles; chief 
involucre-bracts in 1—2 series, equal, thin, membranous-margined, with a few very short 
ones outside. Corolla yellow. Akene terete, 8—] O-ribbed, with a wide basal thickening 
which is hollowed at the insertion and produced upward into a sharp denticulate collar-like 
rim. Pappus of scales terminating each in an awn; scales 4—10, usually 5, mostly 
short, tapering above; awn scabrous, long or short. (Gk. micros—small, seris—chicory. ) 
A. Leaves linear to spatulate; chief bracts of the involucre obtuse; akene contracted 
under the tip; scale-like base of the pappus ovate. U. 
M. dougilasii Gray 
AA. Leaves linear to lanceolate; chief bracts of the involucre acute or acuminate; 
akene not contracted under the tip; scale-like base of the pappus oblong to lanceolate. 
WU. ees M. bigelovii Gray 
UROPAPPUS 
Annual, with short branched stem. Leaves laciniately lobed or pinnatifid. Heads 
erect; peduncles scape-like, long, thickened above; involucre-bracts imbricated in 2 or 
more series, thin, scarious-margined, the outer successively shorter; receptacle somewhat 
chaffy in the center. Corolla yellow. Akenes black (ours), terete, 8—10-ribbed, glab- 
rous with scabrous ribs, the basal callosity not angled. Pappus of chaffy scales: scales 
5, 2-toothed, elongated, flat, hispid, short-awned at tip. (Gk. oura—a tail, pappos== 
pappus; because the pappus-scales are awned.) FE. (U. macrochaetus.) ; 
U. linearifolius Gr. 
SCORZONELLA 
Biennial (ours), glabrous; roots fusiform. Leaves entire to laciniately pinnatifid. 
Heads | or rarely few on a peduncle; peduncles long, scape-like; involucre-bracts herba- 
ceous, imbricated, in several series, the inner long-acuminate, the outer shorter and acute. 
Corolla yellow. Akene linear or somewhat turbinate, smooth or 8—10-ribbed or -striate, 
truncate. Pappus in ours of 5 or 10 bristles or awns which are dilated into scale-like 
bases (except in S. borealis); scale deltoid to linear-lanceolate; awn straight, scabrous to 
plumose. (Diminutive of Scorzonera, another genus of Compositaceae. )
