Illustration of Chenopodium subglabrum large; 1 to 2 mm across, exposing a jet-black fmit at maturity diat readily separates from tlie pericarp (fruit wall). Fruiting occurs in late June-July. Cheiiopod'wm subglabrum sometimes occurs with and is related to Chenopodium leptophyUum. They both have linear, single- veined leaves but tlie latter are farinose white (mealy usually wiiitish colored). Chenopodium leptophylhmt also has densely- clustered flowers, a relatively unbranched growtli fomi, fmits usually 1 mm or smaller, and seeds which do not detach from the pericarp. Distribution: This species is known from the Great Plains, extending from Manitoba to Alberta, and south to Kansas and Nevada. It is also in the Midwest, including Michigan and Missouri. Plants of the Pacific Northwest, including Washington, Idaho and Oregon, are said to differ from Great Plains material (Crawford 1973) and tlieir proper disposition has not been resolved. It is centered in tlie Nebraska Sandhills and widely scattered in five eastern Montana counties. The species was documented in Powder River County and on BLM-administeied lands for die first time during tliis study, where it was found in the northeastern comer of the County. HRbit»t: CJienopodium subglabrum occupies two main kinds of settings, namely sparsely vegetated sand dunes and sandy tenaces of major rivers on the plains. Only one of the five Montana records, located in Custer County, was from a riparian setting on the Tongue River. All five records represent sandy ecological sites. This species is a Appendix C-6
