The leaves are completely or only sawn over the middle.
Single inflorescence and leaves

The Carpathian spar shrub is an upright shrub up to 2 meters high . The branches are thin, more or less round, not striped, glabrous or almost glabrous. They are initially red-brown and later turn gray-brown to black-brown. The buds are brownish, egg-shaped, 1 to 3 millimeters long, glabrous and pointed. They form several bud scales. The leaves are divided into a petiole and a leaf blade. The stem is 1 to 2 millimeters long and bare. The leaf blade is elliptical to lanceolate, 1 to 2.5 inches long and 0.5 to 1.5 inches wide, glabrous on both sides or with downy hair on the axils of the leaf veins. The base is wedge-shaped, the end of the leaf pointed or rarely blunt, the edge of the leaf completely or two to five times sawn.

The inflorescences are stalked, umbel-shaped and 2 to 4 centimeters long with a diameter of 2 to 3 centimeters. They have 9 to 15 flowers. The flower stalks are 1 to 1.5 inches long. The bracts are lanceolate, glabrous and soon fall off. The flowers are 7 to 10 millimeters in diameter. The flower cup is wide, bell-shaped and bare on the outside. The sepals are ovate-triangular, 1.5 to 2.5 millimeters long, glabrous or slightly downy, and have a blunt or pointed end. They are bent back at the fruit. The petals are white, more or less circular, 3 to 4.5 millimeters wide and glabrous. Their base is nailed short . The approximately 45 stamens are longer than the petals. The discus is yellow, wavy, ring-shaped or irregularly lobed. The stylus is shorter than the stamens. Hairy follicles are formed as fruits .

Distribution and ecology

Natural habitat on the Gösing near Ternitz

The natural distribution area extends from Central Europe (eastern Austria, Hungary, Slovakia, the south of Poland) to south-eastern Europe (Slovenia, Croatia, Serbia, Macedonia, Montenegro, Bosnia and Herzegovina, Bulgaria, Romania), Eastern Europe (Moldova, western Ukraine and the northern part of Russia) and Kazakhstan to Siberia , the Kuril Islands , Mongolia, China, Korea and Japan (in the north of Honshū and on Hokkaidō ). It lies in the nemoral and boreal zone and is assigned to winter hardiness zone 4 with mean annual minimum temperatures between −34.4 ° and −28.9 ° Celsius (−30 to −20 ° Fahrenheit ). The species grows in cool, moist forests on well-drained, fresh to moist, moderately nutrient-rich, acidic to neutral, sandy or gravelly humus soils on sunny to light-shady, cool summer and winter cold locations. The species is frost hardy . She avoids soils with a higher lime content. In China, the species grows in mixed forests, on grass-covered slopes and on rocky ground in montane locations at altitudes of 700 to 1600 meters.
