description

Vegetative characteristics

The Tauern willow is an upright shrub with a broad canopy and reaches heights of 1 to 4 meters. The bark of the branches is bare and shiny.

The leaves are divided into a petiole and a leaf blade. The petiole is 5 to 10 millimeters long and has no glands on top. The leaf blade is elliptic to oblong-elliptical to wide-inverted-eilanzettlich at a length of 3 to 10 cm. It is green on both sides. When dried, they are mostly black spots. The leaves are not frosted, they can only be indistinctly frosted on long shoots. The leaf veins protrude on the bare and shiny underside of the leaf .

Generative characteristics

Flowering occurs between May and July before the leaves unfold.

Chromosome set

In the Salix genus , the basic chromosome number is x = 19. The Tauern willow is mostly hexaploid and the chromosome number is usually 2n = 114. For Italian populations there are also reports for 2n = 152.

Occurrence

The Tauern pasture occurs only in Italy and Austria.

In Austria it occurs in the federal states of Upper Austria, Styria, Carinthia, Salzburg and Tyrol. The focus of the Austrian occurrence is in the Central Alps . The localities range from the Stubai Alps on the Tux and Zillertal Alps , the High and Low Tauern including Defereggengebirge , Kreuzeckgruppe , Nock , Koralpe , Saualpe and Seetal Alps to Stubalpe and the Seckau Alps . There are individual deposits in the northern Alps, for example on the Rofan , Hochkönig and Dachstein . In the Austrian Southern Alps, the Tauern pasture occurs on the western edge of the Carnic Alps and in the Gailtal Alps .

In Styria and Carinthia, the Tauern pasture is completely protected, in Salzburg and Tyrol it is partially protected.

In Italy, the Tauern pasture was found in the five provinces of Bozen (South Tyrol), Trento , Brescia , Belluno and Udine . Information from Switzerland for the Lower Engadine could not be confirmed.

The Tauern pasture occurs in the montane to subalpine altitude range, in Austria at altitudes of 1300 to 2200 meters. The focus is on the subalpine level. There are also individual occurrences outside of this altitude range, for example at Kals at 1250 meters and at the Grossglockner High Alpine Road at 2300 meters. The main occurrences are in the green alder bush forest, in high-montane to sub-alpine willow bushes over silicate in alluvions and riverside pioneer locations of rivers.

Systematics

Tauerngasleitung willow ( Salix mielichhoferi ) is connected to the black willow ( Salix myrsinifolia used) and is together with the latter in a Salix nigricans - aggregate provided.

Salix mielichhoferi was named by its first describer Anton Sauter after the Salzburg botanist Matthias Mielichhofer , who was the first to collect this species. The locus classicus is the now dilapidated Schappachalm, southwest of Hüttschlag at around 1580 m above sea level, in the Ankogel group , Hohe Tauern, Salzburg.
