Annual or perennial herbs, rarely suffrutescent, often strongly scented, usually either 
glandular or covered with a farinose pubescence of small white inflated hairs. Leaves alternate, 
usually petiolate, the blades entire, dentate, or pinnatifid. Flowers perfect or rarely unisexual, 
ebracteate, small, usually glomerate, the glomerules variously arranged; perianth usually 5-part- 
ed, rarely 3- or 4-parted or lobed, the segments concave, often carinate or corniculate-append- 
aged, herbaceous. Stamens 5 or fewer, hypogynous or subperigynous; filaments sometimes 
connate at the base; anthers didymous or oblong. Style usually wanting; stigmas 2-5, subulate 
or filiform. Utricle ovoid and erect or depressed and globose, shorter or longer than the calyx, 
the pericarp membranaceous or fleshy, free from or adherent to the seed. Seed horizontal 
or vertical; embryo annular or incompletely annular, surrounding the copious farinaceous 
endosperm; radicle inferior or centrifugal. 
Type species, Chenopodium rubrum L. 
Seeds all or chiefly horizontal. 
Embryo completely encircling the endosperm; plants never with glands 
on leaves and inflorescence, usually farinose. 
Leaf-blades lustrous on the upper surface, rhombic or broadly 
rhombic. I. Ursica. 
Leaf-blades dull on the upper surface. 
Plants glabrous throughout, flowering from the top to the base; 
leaf-blades entire. TI, PoLysPERMA. 
Plants farinose, at least on the younger parts, usually flowering 
at the top. 
Leaf-blades cordate or subcordate at the base, bright-green, 
nearly glabrous. III. Hypripa. 
Leaf-blades rounded or truncate to attenuate at the base. 
Pericarp free from the seed, or, if adherent, the blades of 
the lower leaves linear or entire or 3-lobed, when 
3-lobed the terminal lobe entire or subentire. 
Leaf-blades linear, narrowly lanceolate, or narrowly 
oblong, entire, or subhastate at the base, short- 
petiolate. 
Calyx-lobes carinate, closely investing the fruit or 
erect; pericarp green or greenish. IV. L&PTOPHYLLA. 
Calyx-lobes not carinate, spreading and slightly 
accrescent in fruit; pericarp red. V. CycLorpra. 
Leaf-blades lance-ovate, broadly oblong, oval, or 
broader, long-petiolate. 
Plants not ill-scented. 
Leaf-blades much longer than broad, entire, or 
obscurely lobed at the base, or the lowest 
ones sinuate-dentate. VI. Bosclana. 
Leaf-blades about as broad as long, conspicu- 
ously 3-lobed. VII. FREMONTIANA. 
Plants very ill-scented, densely farinose; pericarp 
adherent. VIIT. VuLVARIAE. 
Pericarp adherent to the seed; at least the lower leaf -blades 
conspicuously sinuate-dentate. IX. Asa. 
Embryo not completely encircling the endosperm; leaves and inflores- 
cence with numerous glands, except in one species. 
Leaf-blades linear, entire; plants without glands. X, ARISTATA. 
Leaf-blades broader than linear, all or most of them dentate or 
pinnatifid; plants with glands on the leaves and inflorescence. 
Pericarp not gland-dotted; inflorescence loosely dichotomous, 
some of the flowers pediceled. 
Calyx-lobes corniculate-appendaged. XI. Incisa. 
Calyx-lobes not corniculate-appendaged. XII. Borrves.
