Prostanthera, commonly known as mintbush or mint bush,[2] is a
genus of about 100 species of flowering plants in the mint
familyLamiaceae, and all are
endemic to Australia. Plants are usually shrubs, rarely trees with leaves in opposite pairs. The flowers are arranged in
panicles in the leaf axils or on the ends of branchlets. The
sepals are joined at the base with two lobes. The petals are usually blue to purple or white, joined in a tube with two "lips", the lower lip with three lobes and the upper lip with two lobes or notched.
Description
Plants in the genus Prostanthera are usually shrubs or subshrubs, rarely trees, with leaves arranged in opposite pairs. The flowers are arranged in panicles in leaf axils or on the ends of branchlets with
bracts and
bracteoles at the base. The sepals are joined at the base but with two lobes. The petals form a tube with two lips, the lower lip with three, usually spreading lobes and the upper lip with two lobes or a notch at the tip. The petal tube is bluish purple to white or more or less red. There are four
stamens, the
anthers often with a small appendage. The
ovary has four lobes and the tip of the
stigma has two branches.[2][3][4]
