COMPOSITE. (COMPOSITE FAMILY.) 
barbellate at the summit. — Perennial white-woolly herbs, with 
entire leaves and corymbed (rarely single) heads. Corolla yel¬ 
lowish. (So named from the resemblance of the sterile pappus 
to the antenna of many insects.) 
1* A. margaritacea, R. Brown. (Pearly Everlasting.) 
Stem erect (l°-2° high), corymbose at the summit, with many heads, 
leaves linear-lanceolate, taper-pointed, sessile; fertile heads 
often with a few imperfect staminate flowers in the centre ; scales of 
the pearly white involucre obtuse or rounded. — Dry hills and woods, 
common. Aug. (Gnaphalium, L., ^-c.) 
2. A. plantagillifdlia, Hook. (Plantain-leaved Ever¬ 
lasting.) Low , spreading by offsets and runners; leaves silky-woolly 
when young, at length green above and hoary beneath ; those of the 
simple and scape-like flowering stems small, lanceolate, appressed; the 
radical obovate or oval-spatulate, petioled, ample, 3-nerved; heads in 
a small crowded corymb; scales of the (mostly white) involucre ob¬ 
tuse in the sterile, and acutish and narrower in the fertile plant. — 
Var. monocephala has a single larger head. (Philadelphia, Mr. Lea.) 
Sterile knolls and wooded banks, common. April, May. 
48, FILAGO, Tourn. Cotton-Rose. 
Heads many-flowered ; the central flowers perfect, but often in¬ 
fertile ; the others pistillate, very slender and thread-form. Scales 
of the involucre few and woolly. Receptacle elongated or top¬ 
shaped, naked at the summit, but chaffy at the margins or toward 
the base, the chaff resembling the proper involucral scales, each 
covering a single pistillate flower. — Pappus of the central flow¬ 
ers capillary, of the outer ones chiefly none. —Annual and low 
branching woolly herbs, with entire leaves and small heads in cap¬ 
itate clusters. (Name from filum, a thread, in allusion to the cot¬ 
tony hairs that cover these plants.) 
1. (*crinaiiica, L. (Herba Impia.) Stem erect, short, 
c ot led with lanceolate and upright crowded leaves, producing a capi¬ 
tate cluster of woolly heads, from which rise one or more branches, 
each terminated by a similar head, and continued in the same man- 
ner: — hence the common name applied to it by the old botanists, as 
i e offspring were undutifully exalting themselves above the pa¬ 
rent. Dry fields, introduced from Europe. July-Oct. 
Subtribe 6. SENEClONEiE. — Pappus soft and capillary. 
Anthers without tails at the base. Receptacle naked. Heads ra¬ 
diate or discoid. Leaves alternate (except in No. 52).
