Quendel speedwell (Veronica serpyllifolia )

The black-spotted blue speedwell ( Veronica serpyllifolia ) Quendelblättriger prize or Thymianblättriger speedwell, is a plant from the family of the plantain family ( Plantaginaceae ).

Features

The Wild Thyme Speedwell is a Hemikryptophyt and reaches stature heights of 5 to 30 cm. The roots go down to 20 cm depth. The plants form a creeping base axis with flowering and non-flowering shoots. The stems are leafy and ascending. All stem leaves are undivided and almost entire. They are short -stalked and bald hairy to weak.

The inflorescence is a short or prolonged terminal raceme or spike, which is clearly separated from the leafy stem: the bracts differ significantly from the true leaves, they are smaller and easier the transition from deciduous leaves to bracts occurs suddenly. The crown is whitish to bluish with darker veining, rather spread - wheel-shaped, often almost radial symmetry. The corolla tube is shorter than wide.

The fruit stalks are about as long or longer than the calyx. The capsule is deeply incised and wider than long. The length is 4 mm, the width to 5.5 mm.

Ecology

Pollination of flowers is done by (Diptera ), it also takes self-pollination. The flowers are proterogyn. The flowering period extends from May to October.

Wetted open up the capsules, and the fruit flaps spread apart; thus the fruit capsules act as Regenballist, ie the bi-convex, to 0.8 mm long, and 0.1 mg of heavy seeds are thrown through raindrops from the fruit and are spreading as Regenschwemmlinge on; in addition they are subject to water distribution and the impact and spread intestine.
