Parr 1, 1916] CHENOPODIACEAE 73 
lobed, acute or obtuse, hyaline sepals, enclosed in a pair of membranaceous, herbaceous, or 
indurate bracts, these entire, not appendaged, united to the middle or to the apex; stigmas 2, 
subulate. Utricle enclosed in the bracts, the pericarp membranaceous, free. Seed com- 
pressed; embryo subannular, surrounding the copious endosperm; radicle ascending or 
superior. 
Type species, Endolepis Suckleyi Torr. 
Leaf-blades ovate to lanceolate, entire or repand-denticulate, not hastate; fruiting 
bracts ovate, not lobed. 
Staminate inflorescence arachnoid-pubescent, the calyx-lobes cristate; leaf- 
blades lanceolate, entire. l. E. dioica. 
Staminate inflorescence merely farinose, the calyx-lobes not cristate; leaf- 
blades ovate-oval, usually repand-denticulate. 2. E. monilifera. 
Leaf-blades, except the lowest, hastate;, fruiting bracts 8-12 mm. long, with 
rounded lobes at the base. : 3. E. Covillei.

Plants erect or spreading, 8-30 cm. high, much branched, or rarely simple below, the 
branches slender, ascending or divaricate, terete, often tinged with red, sparsely farinose or 
glabrous; leaves numerous, spreading or appressed and imbricate, sessile, the blades ovate to 
lanceolate or elliptic, 0.7—3.5 cm. long, 2-11 mm. wide, the upper ones reduced, acute or acumi- 
nate at the apex, rounded to acute at the base, entire, thick and succulent, glaucous, sparsely 
farinose when young; staminate flowers in small glomerules, these in the upper axils or in short, 
dense or interrupted, mostly simple, terminal spikes, the pistillate flowers solitary in the lower 
axils, sessile; staminate calyx cleft to the middle, the lobes triangular, acute, each with a low 
fleshy crest on the back; pistillate calyx of 3 or 4 entire or lobed, distinct, obtuse, hyaline sepals; 
fruiting bracts ovate, 2 mm. long, acute, farinose, united to the apex; seed 1.5 mm. broad, the 
radicle superior.

Annual, branched from the base, the branches stout, 8-15 cm. long, decumbent or ascend- 
ing, terete, simple or sparsely branched, densely and finely white-furfuraceous, or glabrate 
in age; leaves alternate, sessile, the blades ovate-oval, 6-12 mm. long, rounded or subcordate 
at the base, acute or obtuse at the apex, densely and finely whitish-furfuraceous, entire or 
usually acutely repand-dentate; flowers dioecious, the staminate glomerules globose, in dense 
or interrupted spikes, these 0.7-2.5 cm. long, usually forming a terminal panicle, the pistillate 
flowers solitary in the axils of the leaves; staminate calyx 5-cleft to the middle, the lobes thin, 
densely furfuraceous; bracts minute, ovate, acute, entire, enclosing 2 shorter sepals; styles 
exserted.
