The petterie ( Petteria ramentacea ) is a small shrub up to 2 meters high from the legume subfamily (Faboideae) with fragrant yellow flowers that occurs on the Balkan Peninsula.
description
The petterie is a deciduous, upright shrub about 2 meters high . The stalk round branches are increased by the leaf bases and through the remaining, hornlike bespitzten stipules strongly knotty. The shoots are initially hairy and are covered by the stipules. Terminal buds are missing. The leaves are alternate and threefold. The rounded, oblong-elliptical to obovate-oblong-egg-shaped leaflets are almost sessile and 2 to 6 centimeters long. The upper side of the leaf is dark green and finally glabrous, the lower side of the leaf is lighter than the upper side. The middle nerve is hairy, the petiole becomes 2 to 4 centimeters long.
The yellow butterfly flowers are 10 to 20 in upright, 4 to 7 centimeter long clusters. The single flowers are about 2 centimeters long and have a short, two-lipped calyx. The upper lip is divided to the base, the lower lip is threefold and hairy silky. The flag is out of focus. A carpel with an upper ovary is formed. The flowering period extends from May to June. The fruits are 3 to 5 centimeters long, straight, strongly flattened and bare pods that contain several seeds. The shiny, light brown seeds reach a size of 5 millimeters.
Distribution and location requirements
The natural distribution area of the Petterie is on the Balkan Peninsula and extends from Croatia, Bosnia and Serbia to Albania. They can be found in steppe trees and dry forests, on dry to fresh, nutrient-rich soils that can be slightly acidic to alkaline. It grows on sandy, sandy-gravelly and sandy-loamy soil. The petterie is sensitive to frost and prefers a hot and sunny climate.
Systematics
Petteria ramentacea is the only species in the genus Petteria . This is counted in the subfamily of the butterflies to the tribe genistae , to which the gorse ( Genista ) and lupins ( Lupinus ) are also counted.
The generic name Petteria refers to the old Austrian geographer and botanist Franz Petter (1789-1858). The specific epithet ramentacea is derived from the Latin word "ramentum" and means "chip" or "splinter". It refers to the thorn-like overgrown stipules.
use
The petterie is sometimes used as an ornamental shrub because of its decorative and fragrant flowers.
