Dicotyledons:two seed leaves (cotyledons)shoot process consisting of:leaves connect to the stem at nodes. each leaf is composed of lamina, leaf stalk (petiole) and strongly formulated most important vein with lateral veins (reticulate)buds in leaf axils and / or at the stop of stem. Root system – major or tap root, with lateral roots. Plant – atmosphere associations. Knowing the sorts of atmosphere in which sure weeds like to improve can help slender down the probable candidates.
