Striped daphne ( Daphne striata )

Vegetative characteristics

The striped daphne is a woody plant, grows as an evergreen small shrub and reaches heights of usually 5 and 15, rarely up to 40 centimeters. The relatively thin, prostrate to ascending, numerous forked branches have a bare, smooth bark .

The sitting leaves are alternate and heaped in rosettes at the branch ends. The leathery leaf blades, which are light blue-green to dark green on both sides, are 1.8 to 3 centimeters long, 3 to 5 centimeters long, narrow-oval to linear with a wedge-shaped base and entire margins.

Generative characteristics

The flowering period extends from May to July. The pleasant, lilac-like scented flowers develop on the leafy branches. Usually 8 to 12 (2 to 15) flowers are in a terminal, dold-like inflorescence . At the bottom there are about 5 millimeters long, dry-skinned and oval-pointed bracts . The hermaphrodite flowers are fourfold. The four pink, corolla-like sepals are fused into a finely striped tube about 15 millimeters long. The sepals are bare. Petals cannot be seen. Two circles, each with four stamens, are attached to the calyx tube. The bald, top permanent ovary having a fruit compartment which an ovule contains.

The bald stone fruit , which can also be interpreted as a hard berry , has an elliptical shape with a length of 1.4 to 1.7 centimeters. At first the fruit is orange-red in color, later the color changes to brown.

ecology

The striped daphne is a nanophanerophyte .

Occurrence

The distribution area only includes the Alps , from the Scottish Alps to Savoy and from the Gotthard to the Karawanken .

The striped daphne is widespread in Austria, or rarely in the federal states of Carinthia, Tyrol and Vorarlberg, from subalpine to alpine altitudes . In Germany, its occurrence is limited to southern Bavaria. There it grows widespread in the Bavarian Alps and in the Allgäu . In the Allgäu Alps, it rises from 860 meters on the Vorderen Heidach near Hinterstein to an altitude of 2200 meters.

The striped daphne thrives best on lime-rich, moist soils , stony pastures, mountain pine forests, dwarf shrub heaths and rock rubble at altitudes of 1000 to 2800 meters. It is regionally a character species of the Erico-Rhododendretum from the Erico-Pinion association, but also occurs in Seslerietea societies.

Toxicity

The striped daphne is highly toxic due to daphnetoxin .
