hairs. Stems erect, 4-12 dm. tall, leafy to the middle, paniculately branched above : leaf- 
blades thickish, spatulate to narrowly oblong-spatulate, or varying to lanceolate or linear- 
lanceolate above, apiculate or acute, narrowed into winged petioles, or the upper ones sessile : 
peduncles glandular-pilose and tomentose: involucres 7-10 mm. long; inner bracts nar- 
rowly linear-lanceolate, somewhat acuminate: pappus fuscous: achenes fusiform, 3.5-4 
mm. long.

naked below the panicle: leaves commonly hirsute; blades spatulate to oblong, oval or 
obovate, 4-15 em. long, undulate or repand, the inner narrowed into winged petioles, the 
upper closely sessile by broad bases : panicle ample or sometimes much reduced : peduncles 
slender, glandular-pubescent : involucres 5-7 cm. long ; inner bracts linear or narrowly 
linear-lanceolate : achenes fusiform, 3-3.5 mm. long : pappus tawny.

mainly basal; blades oblong-oblanceolate, 4-12 cm. long, acute or apiculate, ciliate, nar- 
rowed into short winged petioles, or those on the stem oblong to ovate, sessile by a broad 
truncate or cordate base: peduncles densely glandular-pilose: involucres 8-10 mm. long, 
inner bracts linear or slightly narrowed upward : achenes fusiform, 4-4.5 mm. long: pappus 
pale tawny.

11. Hieracium argyratum Small. Foliage pubescent throughout. Stems 2.5-5 
dm. tall, usually several together, corymbose and glandular above: leaves mainly basal; 
blades spatulate to oblong, 2-9 cm. long, quite shaggy with hairs similar to those on the 
lower part of the stem, those of the upper stem-leaves with broad bases and sessile : pedun- 
cles glandular-pubescent: involucres 10-11 mm. high; inner bracts attenuate: pappus 
silvery white: achenes fusiform, 3-3.5 mm. long. 
In pine lands, peninsular Florida. Spring. 
3. SITILIAS Raf. 
Biennial or perennial caulescent or scapose usually upright herbs. Leaves some- 
times all basal ; blades irregularly toothed, pinnatifid or sometimes entire. Heads yellow, 
long-peduncled. Involucres oblong to campanulate, double; inner of several narrow 
slightly united bracts; outer of several series of much smaller bracts. Rays yellow, trun- 
cate and toothed at the apex. Anthers sagittate at the base. Stigmas stout, rather 
obtuse.  Achenes oblong to fusiform, beaked, usually 5-ribbed, pubescent or scabrous. 
Pappus of numerous brownish hair-like bristles accompanied by a ring of hairs at their 
bases. [ Pyrrhopappus DC.] FArsE DANDELION. 
Caulescent: stems branching: heads several. 
Bracts of the outer involucres fully 14 to over 14 as long as the inner: heads fully 
2.5 em. long at maturity. 
Bracts of the outer involucres less than 24 as long as the inner: heads 2 cm. long ne 
at maturity or shorter. 2. S. multioan st. 
Scapose: scapes simple: head solitary. 3. S. grandiflora. 
1. Sitilias Caroliniana (Walt.) Raf. Foliage glabrous or nearly so. Stems T 
1-1.5 dm. tall, usually branched: leaves various; blades more or less deeply sa a 
sometimes merely denticulate or nearly entire, these conspicuously elongated : invo € 
12-26 mm. long; inner bracts narrowly linear ; outer bracts narrower, fully 4 to ores : 
long as the inner: ligules yellow: achenes about 5 mm. long, ribbed, somewhat rufous. 
[.Pyrrhopappus Carolinianus ( Walt.) DC.] 
In dry soil, Delaware and Missouri, south to Florida and Texas. Spring to fall. 
2. Sitilias multicàulis (DC.) Greene. Foliage minutely pubescent, or dti :
