Vegetative characteristics
The lying gentian is an annual herbaceous plant with heights of 2 to 5, rarely up to 7 centimeters. The stems are prostrate or ascending, unbranched or with a few basal branches.
The opposite leaves are provided with a short sheath at the base. The simple, rather fleshy leaf blade is narrowly obovate to oblong with a blunt upper end. The leaf margin is cartilaginous.
Generative characteristics
The hermaphrodite flowers are radially symmetrical with a double flower envelope . The calyx teeth are broadly triangular with a blunt upper end. The crown is 10 to 20 millimeters long, narrowly inverted-conical, steel blue and greenish-white towards the base.
Occurrence
In Europe, Gentiana prostrata occurs only in the eastern Alps in Austria, Switzerland and northeastern Italy. It grows there on damp, stony slopes at altitudes of 2200 to 2720 meters. In the Alps it finds its optimum in the societies of the Oxytropido-Elynion association.
Taxonomy
