Vegetative characteristics

The red-nerved snakeskin maple often grows as a multi-stemmed, small, deciduous tree and reaches heights of 12 to 15 meters. It forms a regular, narrow, funnel-shaped tree crown . The bark , which remains smooth for a long time, is green to silvery-green, with white longitudinal stripes. The bark of the branches is initially blue and white. The buds are frosted blue and white.

The constantly against arranged on the branches leaves are divided into petiole and leaf blade. The petiole is 2 to 6 inches long. The three-lobed leaf blade is 6 to 15 centimeters wide with a rounded blade base. The side lobes are slightly above the middle. The leaf edge is sharp and unevenly serrated. The upper side of the leaf is dark green and the underside is slightly lighter. Initially the leaf nerves and nerve corners are hairy reddish brown, in summer only the nerve corners are. The leaves turn orange to carmine red in autumn.

Generative characteristics

The flowering time is in May after the leaves have unfolded. The yellow-green flowers are arranged in terminal, rust-red hairy inflorescences . The flowers are unisexual.

The fruit stalks are about 5 millimeters long. The fruits are 2 to 3 centimeters long, initially hairy and later glabrous. The wing is spread at an obtuse angle.

Occurrence

The distribution area is only on the Japanese islands of Honshū , Kyushu and Shikoku .

The red-nerved snakeskin maple grows in cool, moist forests on moderately nutrient-rich, well-drained, fresh to moist, acidic to neutral, sandy-humic or gritty-humic soils in sunny to light-shaded locations. The red-nerved snakeskin maple is usually frost hardy .

Systematics

The species Acer rufinerve belongs to the Macrantha section of the genus Acer . It was first described in 1845 by Philipp Franz von Siebold and Joseph Gerhard Zuccarini in the treatises of the Mathematical-Physical Class of the Royal Bavarian Academy of Sciences. Munich , Vol. 4, 2, p. 155.

use

The red-nerved snakeskin maple is often used as an ornamental plant because of its unusual autumn colors .
