The Lapland willow ( Salix lapponum ) is a small shrub from the genus of the willow ( Salix ) with initially silky hairy branches and at least initially felty hairy leaf blades. The natural range of the species is in Europe and extends to the east of Siberia.
description
The Lapland willow is up to 1.5 meters high, broadly upright and densely branched shrub with thin, initially silky hairy and later bare, dark brown, shiny shoots. The leaves have no or only poorly developed stipules and a 3 to 8 millimeter long stalk. The leaf blade is 2.5 to 8 centimeters long, 0.8 to 3 centimeters wide, elliptical to obovate, less often lanceolate, pointed or pointed, with entire margins or at most slightly wavy notched, with a rounded to wedge-shaped base. The upper surface of young leaves is hairy white, later glabrous and olive green, the underside is permanently gray-tomentose.
The inflorescences are about 3 centimeters long, elongated, sitting and conspicuously silvery silky haired catkins . The bracts are dark brown, long hairy with an elongated nectar gland. Male flowers have two bare stamens . The ovary of female flowers is almost sessile and hairy. The stylus is long, the scars are elongated and divided. The Lapland willow flowers shortly before the leaves shoot from May to June.
The number of chromosomes is 2n = 38.
Occurrence and location requirements
The natural distribution area in Europe extends from Northern Europe (Finland, Norway, Sweden, England , Scotland ) through Central Europe (Czech Republic, Slovakia, southeast of Germany, Poland) to Eastern Europe (Belarus, the Baltic States , Ukraine, Russia) and Southern Europe (south from France, northeast of Spain, Bulgaria, Romania). In Asia, the distribution area extends from west to east Siberia . The Lapland willow grows in swamp and swamp areas in swamp forests, on swampy ground and in wet and wet meadows in sunny and cool locations. The distribution area is assigned to winter hardiness zone 4 with mean annual minimum temperatures of −34.4 to −28.9 ° C (−30 to −20 ° F).
Systematics
The Lapland willow ( Salix lapponum ) is a species from the genus of willows ( Salix ) in the willow family (Salicaceae). It was first scientifically described by Carl von Linné in the Species Plantarum in 1753 . The generic name Salix comes from Latin and was already used by the Romans for various types of willow. The epithet lapponum derives from Medieval Latin Lappo for Lappe ago.

The Lapland willow is rarely used.
