description
They are relatively small, annual to perennial herbaceous plants that grow upright to prostrate and can take root at the leaf nodes.
The lower leaves are in a rosette or whorled or opposite, the upper leaves in many species are alternate. The leaves are slowly narrowed into the leaf base or the petioles are winged.
The flowers are in terminal and usually one-sided racemose inflorescences . The hermaphrodite, zygomorphic flowers are usually five-fold. The green calyx is funnel-shaped to bell-shaped and usually deeply split into five calyx tips. The petals are fused into a corolla tube (it can be tubular to bell-shaped). The lower lip of the corolla is three-lobed and spread out flat towards the front or below. The two side lobes are usually significantly larger than the middle lobe. Above the middle lobe there are two elongated, lengthways, often color-contrasted bulges. The upper lip is usually much shorter than the lower lip. It is bilobed, the two lobes in most species are only short and narrowly lanceolate, and the upper lip is already narrowed before the beginning of the lobes. Usually four stamens are formed. The upper ovary usually consists of two fused carpels , the stigma is bilobed. There are fruit capsules formed that contain tiny seeds.
Distribution and location requirements
The genus occurs in East and South Asia as well as Australia (north to Japan and Russia , south to New Zealand , and west to India ).
Mazus pumilus and Mazus miquelii arenaturalizedin some places in North America .
The different species colonize very different habitats such as roadsides, rocks on the seashore or mountain pastures. Most species occur in humid areas of the flatlands or in mountain regions.
