Sections of Chenopodium 
Section I. f Agathophyton (see below). Perennial. Perianth with 5 segments. Stamens 5. 
Stigmas 2 — 5, long. Seeds vertical, except the terminal ones of the cymes which are horizontal, 
large. 
Section II. Chenopodiastrum (p. 155). Annual. Perianth with 5 segments. Stamens 5. 
Stigmas short. Seeds horizontal.
