The crested devil's claw ( Physoplexis comosa ) is the only species of the plant genus Physoplexis in the bellflower family (Campanulaceae). It is native to Austria, Italy and the former Yugoslavia.
features
The crested devil's claw is a perennial , herbaceous plant that reaches heights of 5 to 15 centimeters. It forms a Pleiokorm turnip. The basal leaves are rounded, kidney-shaped, roughly and deeply serrated and have long stalks. The stem leaves are oblong-ovate. The lower ones narrow into the stem, the upper ones are roughly sawn and sessile, with a wedge-shaped base. The crown is pale purple and 16 to 20 millimeters long. It is contracted from an egg-shaped base to a beak that is dark purple at the tip. In contrast to the devil's claws ( Phyteuma) , however, these tips remain attached and do not separate later. The stylus ends in two scars.
The flowering period extends from July to August.
The species has chromosome number 2n = 34.
Occurrence
The crested devil's claw occurs in the southern limestone Alps from Lake Como to the West Karawanken and the Julian Alps. So it occurs wild only in the areas of Austria, Italy and Slovenia. It grows in the montane to subalpine level in shady limestone and dolomite rock crevices at altitudes of 1000 to 1700 (rarely from 60 to 2000) meters. It finds its optimum in societies of the sub-association Physoplexido-Potentillenion caulescentis.
Taxonomy
In the past, this species was placed in the genus Phyteuma . Ferdinand Schur established a separate genus for this species. But Stephan Ladislaus Endlicher formed the name Physoplexis in 1838, who sect the crested devil's claw within the genus Phyteuma in a separate section called Phyteuma . Physoplexis (in the work: Genera , p. 517). The name Physoplexis comes from the Greek and means "bladder, braided" because of the blister-shaped connected petals. The specific epithet comosus is derived from Latin and means "schopfig".
use
The crested devil's claw is rarely used as an ornamental plant for rock gardens.
