Chenopodium pratericola

Leaf Bottom
South of Sceptre
27-July-2002

This plant is likely C. pratericola.  The 3-veined leaves with densely farinose leaf bottoms distinguish it from C. subglabrum whose leaves are mostly 1-veined and lightly farinose to almost glabrous.

The 3-veined leaves also distinguish it from C. leptophyllum, whose leaves are 1-nerved.  In addition, the leaves of C. pratericola are narrowly lanceolate or oblong, sometimes slightly lobed at the base, and often over 4 mm broad.  The leaves of C. leptophyllum are linear, entire, and mostly less than 4 mm broad.

The rest of the points in the keys leading to Chenopodium pratericola are as follows:
