A Key To Wildflower Leaf Arrangement
|Basal leaves are leaves which grow at the bottom of the plant stem. If the leaves are growing on the stem itself they are called stem leaves. *Note: Plants frequently have both basal and stem leaves.||Opposite||Whorled leaves surround the stem in a circular pattern. This pattern is composed of three or more leaves.
** Please note: We unfortunatly were unable to find any flowers with whorled leaves.
|Alternate leaves grow at different and seperate points on the stem ( leaves never grow across from each other) so that an alternate pattern is formed.|
|Opposite leaves parallel each other as they grow up the stem so that an opposite pattern is formed.|
|Additonal Leaf Information:
|Whole Leaves||Toothed Leaves||Lobed Leaves||Divided Leaves|
|Whole leaves have smooth uniform edges.||Toothed leaves have jagged edges.||Lobed leaves have deep indentations called sinuses *Note: The sinuses are not so deep that the leaf is fully split.|
|Divided leaves are split into different parts. These seperate parts are called leaflets. Many leaflets form a compound leaf.|
