Malva neglecta Wallr.
Spreading annual or biennial.
Cotyledons are heart-shaped with three main veins. Leaves are alternate, rounded with a heart-shaped base, palmately veined, hairy and found on long, slender, hairy petioles. Margins are round-toothed and obscurely lobed.
Spreading and partly erect stems are branched from the base and up to 1 foot tall.
Flowers and fruit
Flowers have five white and purple-tinged petals; flowers are formed on stalks in the leaf axils. Fruit are capsules that resemble a button or cheese wheel. Each capsule contains 12 to 15 compartments; each compartment has one reddish brown to black, flattened, and rounded seed with a notch.
Seeds and stem fragments.
Venice mallow (Hibiscus trionum L.) Differs by having leaves with three distinct, coarsely toothed lobes that may be further divided into as many as seven lobes; and pale yellow flowers with a purple base.
