Vegetative characteristics

The Quendel speedwell is a perennial herbaceous plant and reaches heights of 5 to 30 centimeters. The roots reach up to 20 centimeters deep. The plants form a creeping basic 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 to slightly hairy.

Generative characteristics

The terminal, short or elongated, racemose or ear-like inflorescence is clearly separated from the leafy stem. The bracts differ significantly from the foliage leaves, they are smaller and simpler, the transition from foliage leaves to bracts occurs suddenly.

The hermaphroditic flowers have a double flower envelope . The corolla is whitish to bluish with darker veins, rather spread out-wheel-shaped, often almost radially symmetrical . The corolla tube is shorter than it is wide.

The fruit stalks are about as long or longer than the calyx. The capsule fruit is deeply sanded and with a length of up to 4 millimeters and a width of up to 5.5 millimeters wider than it is long.

The number of chromosomes is 2n = 14 or 28.

ecology

The Quendel Speedwell is a hemicryptophyte and a root creep pioneer .

The pollination is carried out by Fly ( Diptera ), it is also self-pollination . The flowers are proterogynous . The flowering period extends from May to October.

When wetted, the capsule fruits open up and the fruit flaps spread apart; thereby the capsule fruits act as a rain ballist, d. H. The biconvex, up to 0.8 millimeters long and 0.1 mg heavy seeds are thrown from the fruits by raindrops and spread as rainworms ; In addition, they are subject to the spread of water and the spread of treads and intestines.

Occurrence

The Quendel speedwell is circumpolar in the northern hemisphere . It grows in meadows , pastures , fields, on ruderal sites , banks and roadsides and in social groups . It thrives best on nutrient-rich and lime-poor soils . It rises to altitudes of 2400 meters. It occurs in Central Europe in societies of the associations Cynosurion, Agropyro-Rumicion, Polygonion avicularis or the order Arrhenatheretalia elatioris.

Systematics

Veronica serpyllifolia was first described by Carl von Linné . Veronica serpyllifolia belongs to the Serpyllifolia section in the subgenus Beccabunga within the genus Veronica .

By Veronica serpyllifolia there are two or three subspecies:

  • Common Quendel speedwell ( Veronica serpyllifolia L. subsp. Serpyllifolia ), with white to pale blue flowers and 10 to 30 centimeters high and distributed from collin to montane. Its chromosome number is 2n = 14 or 28.
  • Low Lying Veronica Serpyllifolia or mountain-thyme-speedwell ( Veronica serpyllifolia subsp. Humifusa (Dicks.) Syme ), with bright blue-purple flowers, 5 to 8 centimeters high and subalpine spread to alpine. Its chromosome number is 2n = 14. It occurs in societies of the milkweed willow associations (Poion alpinae) or Lägerfluren (Rumicion alpini).
  • Veronica serpyllifolia subsp. trichocaulis Peev : It occurs in Bulgaria .
