VIII, Sueda.—Erect or prostrate herbs. or shrubs. eaves ternate, fleshy, 
more or less terete. Perianth in fruit not appendiculate or with

i, CHENOPODIUM, Linn. 
Flowers hermaphrodite, without bracts or bracteoles. Perianth 5- 
(very rarely 1- 3- or 4-) lobed ; lobes concave, sometimes keeled but 
not appendaged, unchanged in fruit. Stamens 5 or fewer, hypo- 
gynous or subperigynous ; filaments sometimes connate at the base ; 
anther-cells globose or oblong. Disk none or annular. Ovary usually 
depressed-globose ; style usually absent ; stigmas 2~5, filiform or 
subulate, free, rarely connate below; ovule subsessile. Utricle 
ovoid and erect or globose and depressed, membranous or rather 
fleshy. Seed usually horizontal ; embryo annular or nearly so, 
surrounding copious floury albumen. 
Herbs, rarely woody at the base, annual or perennial, often glandular pubescent, 
rarely glabrous ; leaves alternate, linear to deltoid, entire to pinnatifid ; flowers 
minute, in globose clusters, which are solitary and axillary or in terminal spikes 
or racemes. 
Distrip. Species about 50, chiefly in temperate regions, rare in the tropics, 
Except possibly C. Botrys and fetidum, the species described have probably been 
introduced into 8. Africa with cultivation,
