|discussion=<p>Presumed native American plants of <i>Chenopodium strictum</i> were recognized as a separate species, subspecies, or variety [C. glaucophyllum Aellen; <i>C. strictum</i> subsp. glaucophyllum (Aellen) Aellen; <i>C. strictum</i> var. glaucophyllum (Aellen) Wahl]. These plants are very variable, and usually have broader leaves and more lax inflorescences, which might be a result of hybridization with other species of the <i>C. album</i> aggregate. The native status of such forms is very questionable. Typical <i>C. strictum</i> also occurs in North America, but seems to be less common. Some narrow species and hybrids of the <i>C. strictum</i> aggregate are recognized in Eurasia (P. Aellen 1928; F. Dvo ák 1989; P. Uotila 1977, 1993, 1997). Some of these taxa, especially C. striatiforme Murr and C. novopokrovskyanum (Aellen) Uotila, are superficially similar to the native North American taxa of subsect. Leptophylla. Eurasian forms of the <i>C. strictum</i> group usually can be distinguished by their venation pattern (in most cases more than three visible veins even in narrowest leaves). Considering the likely alien status and wide variability of <i>C. strictum</i> in North America, no attempt is made here to subdivide it into infraspecific entities.</p>
