CARDUACEAE 1237 
at the apex, densely white-woolly: basal leaves several; blades thin, variable, but 
usually oblong, 3-6 cm. long, and 2-4 cm. wide, 3-ribbed, mucronate, rather abruptly con- 
tracted into petiole-like bases less than 3 their length : cauline leaves erect, remote ; blades 
linear-lanceolate, about 1 em. long, acute: head solitary : involucre about 10 mm. high 
at maturity ; bracts purplish except the white petaloid tips. 
2 In rich woods, mostly in the mountains, Pennsylvania to middle Georgia. Also in Louisiana. 
pring. 
64. ANAPHALIS DC. 
Perennial caulescent herbs, with woolly or tomentose foliage. Leaves alternate : 
blades narrow, entire, sessile. Heads discoid, dioecious, in terminal corymbs. Involucres 
thick : bracts in several series, scarious, pearly or white. Receptacle convex, not chaffy. 
Staminate flowers with slender or filiform corollas, united stigmas and pappus of several 
hair-like bristles. Anthers tailed at the base. Pistillate flowers with tubular corollas, 
distinct stigmas and pappus of copious hair-like bristles. Achenes oblong or nearly so. 
1. Anaphalis margaritacea (L.) Benth. & Hook. Foliage white-woolly throughout. 
Stems usually tufted, 2-4 dm. tall: leaf-blades linear or nearly so, 5-15 em. long, acute, 
entire, sessile: heads numerous, conspicuous: involucres campanulate to subglobose, 5-6 
mm. high : bracts numerous, ovate to oblong, mostly obtuse, pearly white, spreading in 
age: pappus-bristles of the pistillate flowers distinct, falling away separately. 
In dry soil or open woods, Newfoundland to Alaska, North Carolina, Kansas and California. 
Summer and fall. PEARLY EVERLASTING. 
65. FACELIS Cass. 
Annual caulescent woolly herbs. Leaves alternate: blades narrow, entire. Heads 
heterogamous, axillary or in clusters. Involucre oblong or ovoid, of several series of nar- 
row bracts, the inner mainly scarious and elongated. Receptacle flat, naked.  Pistillate 
flowers marginal, each with a slender truncate or obscurely lobed corolla. Perfect flowers 
central, some of them fruit-producing, each with a 5-lobed corolla. Anthers sagittate at the 
base, the auricles acuminate. Achenes pubescent, beakless. Pappus of numerous white 
plumose bristles, concreted at the base. 
1. Facelis apiculàta Cass. Stem commonly branched at the base, the branches 2- 
12 em. tall, leafy, lanate : leaf-blades linear-spatulate to linear, 0.5-1 cm. long, apiculate, 
revolute, more woolly beneath than above: involucres mostly clustered : bracts ovate to 
oblong or linear, scarious except a green midrib, the outer woolly, the inner 5-7.5 mm. 
long, glabrous : achenes 1-1.5 mm. long, the hairs merging into the pappus which is sev- 
eral times longer than the achene. 
In grassy commons and waste places, eastern Georgia. Native of southern South America. 
66. GNAPHALIUM L. 
Annual, biennial or perennial caulescent herbs, with woolly or sometimes glandular foli- 
age. Leaves alternate: blades entire, often sessile or decurrent, usually narrow. Heads 
discoid, variously disposed. Involucres with both pistillate and perfect flowers: bracts 
scarious, in several series. Receptacle not chaffy, usually pitted. Pistillate flowers in 
several series, with filiform corollas. Anthers sagittate, with tailed auricles. Achenes 
terete or slightly flattened, not ribbed. Pappus a single series of hair-like bristles either 
distinct or cohering at the base, not plumose, deciduous. CupWEED. EVERLASTING.
