Name: Oak-leaved goosefoot, Chenopodium
Other Names: chénopode glauque, Saline goosefoot, ansérine glauque, C. salinum Standl.
Family: Goosefoot Family (Chenopodiaceae)
General Description: Annual, reproducing only by seed. Similar to Lamb's-quarters in general appearance but much shorter, rarely exceeding 40cm (16in.) in height and often prostrate or nearly so.
Leaves: Leaves alternate (1 per
node), generally smaller, up to 4cm (1-1/2in.) long, white on
the undersurface, green or sometimes slightly reddish on the
upper surface, shallowly and more or less uniformly round-toothed
around the margins.
Flowers & Fruit: Granular clusters of tiny greenish flowers (later fruits) smaller and forming short, irregular spikes in the axils of the upper leaves; seeds dark brown. Flowers from July to September.
Habitat: Oak-leaved goosefoot occurs throughout Ontario along roadsides and rights-of-way, in pastures, waste places, edges of fields and gardens in situations ranging from dry to moist soils and from very coarse gravels to fine-textured clays, and is often the main weed in depressional areas with saline soils.
