  • Bellvine

    Ipomea plebeia

    • In north Queensland, red flowered bellvine (I. hederifolia) is more common.
    • Seed leaves are v-shaped with a broad flat base extending slightly beyond the sides (see also cowvine, and common morning glory). True leaves have scattered hairs, with a notched base, becoming more pronounced as leaves mature. The notched leaf base formed by large basal lobes is very pronounced and regular, unlike in cowvine.
  • Australian Bindweed

    Convolvulus erubescens

    • Seed leaves are nearly square with a rounded base and a deeply notched tip (unlike European bindweed).
    • The first three or four true leaves are oblong with rounded or bluntly pointed tips. The next three to four leaves are arrowhead-shaped and similar to European bindweed.
  • Bluebells

    Wahlenbergia sp.

    • There are a number of blue bells which are very difficult to separate into different species. Different species can be annual or perennial.
    • Seedlings form a rosette. Leaves are alternate or opposite and all occur at the base of the plant or on the lower stem. Perennial species often have a woody rootstock or spread by rhizomes.
  • Boggabri

    Amaranthus mitchellii

    • Seed leaves are elongated oval-shaped.
    • Mature plants are hairless, yellowish to reddish, erect to semi-erect plant. Leaves may have notched tips.
  • Bathurst Burr

    Xanthium spinosum

    • The seed leaves are elongated oval-shaped. The first true leaves are notched on the lower part of the leaf margins and have fine white hairs. Later leaves are lobed.
    • Mature plants are compact, multi-branched and robust, usually 0.6–0.9 m tall. Stems of mature plants have many three pronged spines, one or two occurring at the base of each leaf or branchlet.
  • Charlock

    Sinapis arvensis

    West, North
    • Mature plant erect to 80 cm, stem branched with longitudinal grooves, hairy, often with red leaf junctions and base.
    • Cotyledons kidney shaped, indented apex, hairless.
