Vegetative characteristics

The Alpine Speedwell grows as a perennial herbaceous plant and reaches a height of 5 to 15 centimeters. The aboveground parts of the plant are hairy or almost bald.

The opposite constantly arranged leaves are sessile. A base sheet rosette is not formed. The simple leaf blade is 10 to 25 millimeters long, with the leaves sitting in the middle of the stem axis being the largest. The blade is egg-shaped, the leaf margin is entire. Mostly there is a glandular cilia and loose hair.

Generative characteristics

The flowering period extends from June to August. The flowers are densely packed in a short terminal cluster . The umbellate has small, leaf-like bracts . The hermaphrodite flowers are slightly zygomorphic with a double flower envelope . The four blue petals are 5 to 7 millimeters wide. The very short corolla tube ends in an unequal four-part, false coronet. As with all speedwell species, it is surmounted by two stamens and a thread-like stylus.

The capsule fruit, which has no glandular hair, is elliptical with a length of 5 to 7 millimeters and a diameter of 4 to 5 millimeters. Unripe fruits are usually tinged with turquoise. The vegetative reproduction is ensured by underground runners .

The number of chromosomes is 2n = 18.

Habit and inflorescence

Occurrence

The distribution area of the Alpen-Ehrenpreis lies in Europe in the Alps and from the Pyrenees to the Balkans and in Scandinavia including Iceland and Greenland. Outside Europe, it occurs in Pakistan, India, Siberia, Tibet and North America. In Austria , the Alpine honorary award is often from the alpine to the subnival altitude level and is absent in Burgenland and Vienna. In Germany , the Alpine Honorary Award occurs only in the Bavarian Alps. In the Bavarian Alps, it rises from an altitude of 1400 meters (Hinteres Traufbachtal in the Allgäu) to 2870 meters.

The Alpine Speedwell is an Arctic-Alpine floral element . It colonizes moist, long snow-covered and slightly acidic soils , fine debris, storage sites and snow valleys at altitudes of 1200 to 3400 meters. It is a character species of the Salicetea herbaceae class, but also occurs in plant communities of the Poion alpinae association or in humid communities of the Nardion association.

Diseases

The alpine speedwell is the rust fungus Puccinia albulensis with Telien affected.
