Marginal pistillate flowers present. 
Receptacle hairy. B. Absinthium. 
Heads numerous, usually paniculate; plant more or less 
shrubby at the base. III. Fricipar. 
Heads few, 1-12, racemose; plant low, herbaceous, from a 
rootstock, 1-3 dm. high. IV. LANATAE. 
Receptacle naked. C. Abrotanum. 
Annual or biennial herbs with bipinnatifid leaves. 
Leaves green; divisions not filiform. V. ANNUAE. 
Leaves white-tomentose; divisions filiform. VI. KLOTZSCHTIANAE. 
Perennials. 
Plant low, rarely more than 1 dm. high, pulvinate-cespi- 
tose; heads many-flowered, in capitate clusters. VII. GLOMERATAE. 
Plant taller, more than 1 dm. high, not pulvinate-cespi- 
tose, either with a rootstock or with a suffruticose 
base. 
Leaves silvery or silky or glabrate, but not tomentose 
beneath. 
Plant low, perennial, herbaceous, with root- 
stocks; heads many-flowered, noddingin asimple 
racemose inflorescence; leaves divided into 
linear or oblong divisions. VIII. NorvEGICAE. 
Plant more or less shrubby at the base; heads 
paniculate. 
Leaves pinnately dissected into narrow divis- 
ions (glabrate forms of A. Abrotanum, A. 
graveolens, and A. lenuis). 
Leaves cuneate, 3-toothed at the apex or the 
upper entire. XVII. BIGELOVIANAE. 
Leaves more or less tomentose beneath. 
Leaves not dissected into narrowly linear more or 
less divergent divisions; these, if narrow, 
very few, directed-forward and entire. 
Leaves greener and glabrate above, at least 
in age. 
Heads 60—100-flowered; leaves twice pin- 
natifid with obtuse divisions, the lower 
long-petioled. IX. FRANSERIOIDES. 
Heads 5-50-flowered; leaves simple or 
once pinnatifid, or, if bipinnatifid, 
with acute lobes and sessile or short- 
petioled. 
Leaves entire or with a few lobes, if dis- 
sected to near the midrib, the lobes 
rather broad [except in A. mexicana]. X. VULGARES. 
Leaves deeply dissected to near the 
midrib; divisions linear or oblong, 
usually more or less cleft. XIII. Discotorgs. 
Leaves white-tomentose on both sides. 
Involucre 3-5 mm. high; leaves entire or 
divided into lanceolate, linear-lanceo- 
late, or oblong divisions. XI. GNAPHALODES. 
Involucre 5-6 mm. high; leaves obovate in 
outline, with short elliptic or ovate divis- 
ions; plant stout. XII. STELLERIANAE. 
Leaves once or twice dissected into linear or fili- 
form, more or less spreading divisions. 
Leaf-segments broadly linear or linear-lanceo- 
late, usually again lobed or toothed. XIII. Disco.torgs. 
Leaf-segments narrowly linear or filiform, 
mostly revolute.
