Chenopodium Chenopodium subsp. striatum, (Krasan.) J. Murr

(b) Subsp. striatum (Krasan.) J. Murr in Urban & Graebner, Festschr. Ascherson 222 (1904):

Leaves oblong, obtuse; margins almost parallel, not or scarcely dentate; stems red-striped. C. & E. Europe, extending westwards to Belgium; introduced in Spain.

It is possible that further subspecies should be recognized in Europe, and even that 22 and 23 might be better so treated.

C. reticulatum Aellen , Bot. Not. 1928: 205 (1928) has the testa of the seeds covered with distinct raised lines, forming a close, more or less quadrate reticulum, the surface between the ridges being minutely dotted; it is probably best considered a variant.

C. zerovii Iljin in Kotov, Fl. RSS Ucr. 4: 650 (1952), from the C. & S. Ukraine, is like 21 but has elongate, horizontally spreading and arcuate-decumbent lower branches and rather thick leaves, very whitish-farinose beneath, ovate in outline, subobtuse at the apex, and held upright. The status of this plant requires further investigation.
