Lobelia Nuttallii R. & S. Syst. 5: 39. 1819. 
Annual, or perhaps biennial, glabrous throughout, 
or puberulent below; stem weak, usually reclining, 
very slender, loosely branched, at least when old, 
1°-3° long. Basal leaves spatulate to oval, obtuse,

slightly spatulate, longer and narrower, entire or 
sparingly glandular-denticulate; flowers 23”-4” long, 
pale blue, loosely racemose; bracts linear or the 
upper subulate; pedicels filiform, 2”-4” long, naked, 
or minutely 2-bracteolate near the base; calyx-lobes 
subulate, longer than the depressed-hemispheric 
strongly ribbed tube, the sinuses unappendaged; cap- 
sule depressed-globose, half-inferior, about 1” long. 
In sandy soil, Long Island to Pennsylvania, Florida 
and Georgia. June—Sept.

Annual, slightly puberulent, usually glabrous; stem ek 
erect, slender, paniculately branched, or simple, 2°-3° = 
high. Stem leaves linear or linear-oblong, 3’-13’ / 
long, 34-13’ wide, the lower obtuse, sometimes 
slightly repand-denticulate, the upper acute, nar- 
rower, entire; flowers racemose, blue, 4-52” long; Va 
lower bracts linear, the upper subulate; pedicels 
erect or ascending, naked, filiform, 1-3” long; 
calyx-lobes linear-subulate, glandular-denticulate, 
equalling or somewhat longer than the narrowly \ 
turbinate tube, mostly shorter than the tube of the 
corolla; capsule oblong-turbinate, 2” long, shorter s 
than the calyx-tube. f

Family 44. CICHORIACEAE Reichenb. Fl. Excurs. 248. 1831. 
CuHIcory FAMILY. 
Herbs (two Pacific Island genera trees), almost always with milky, acrid or 
bitter juice, alternate or basal leaves, and yellow, rarely pink, blue purple or white 
flowers in involucrate heads (anthodia). Bracts of the involucre in I to several 
series. Receptacle of the head flat or flattish, naked, scaly (paleaceous), smooth, 
pitted, or honeycombed. Flowers all alike (heads homogamous), perfect. Calyx- 
tube completely adnate to the ovary,'its limb (pappus) of scales, or simple or 
plumose bristles, or both, or wanting. Corolla gamopetalous, with a short or long 
tube, and a strap-shaped (ligulate) usually 5-toothed limb (ray). Anthers con- 
nate into a tube around the style, the sacs sagittate or auricled at the base, not 
tailed, usually appendaged at the summit, the simple pollen-grains usually 12-sided. 
Ovary 1-celled; ovule 1, anatropous; style very slender, 2-cleft, or 2-lobed, the 
lobes minutely papillose. Fruit an achene. Seed erect; endosperm none; radicle 
narrower than the cotyledons. 
About 70 genera and 1500 species, of wide geographic distribution. The family is also known 
as LIGuLIFLoRAE, and is often regarded as a tribe of the COMPOSITAE. 
* Pappus of scales, or of scales and bristles, or none. 
Flowers blue or white; pappus of blunt scales. 1. Cichorium, 
Flowers yellow. . 
Bracts of the involucre membranous, or herbaceous. 
Pappus none; achenes 20-30-nerved. 2. Lapsana. 
Pappus none; achenes 8-10-ribbed. 3. Serinea.
