Systematics
Order : Astern-like (Asterales)
Family : Daisy family (Asteraceae)
Subfamily : Asteroideae
Tribe : Inuleae
Genre : Pentanema
Type : Rough elephant
Scientific name
Pentanema hirtum

The Raue Alant or Rauhaarige Alant ( Pentanema hirtum ) is a species of the genus Pentanema within the family of the Asteraceae .

description

The stem is hairy protruding.
The leaves are clearly network-nerved underneath.
Habitus, the hair is clearly visible.
The leaves are covered on the upper side with sessile glands.
The basket bracts are all of the same length and linear to lanceolate as well as protruding wire-haired.

The wire-haired elephant is characterized above all by the coarse hair on all sides ( indument ).

Vegetative characteristics

The rough elephant is a perennial herbaceous plant that can reach heights of 15 to 50 centimeters. The above-ground parts of the plant (leaves and stems ) are very hairy and coarse.

The somewhat leathery leaves are narrow, elliptical, more or less entire and hairy on both sides. The upper stem leaves have a narrowed or rounded base, but do not encompass the stem. They often have protruding veins.

Generative characteristics

The flower heads stand alone, rarely in groups of up to three at the end of the stem. They are 2 to 5 centimeters in diameter. The stiff-haired bracts are all almost the same length.

The number of chromosomes is 2n = 16.

Occurrence

The wire-haired elephant is widespread from West Asia via East and Southeast Europe to Central Europe. In Germany it reaches the western border of its distribution area.

The wire-haired elephant is common continentally on poor, dry soils . It grows in Central Europe on dry or semi- arid grassland in or near light oak or pine forests . It does best on calcareous soils . In Central Europe it is a character species of the Potentillo albae-Quercion petraeae association, but also occurs in plant associations of the Geranion sanguinei or Festucion valesiacae associations.

Taxonomy

The first publication took place under the name ( Basionym ) Inula hirta L. by Carl von Linné After Gutiérrez-Larruscain et al. In 2018, some species from the genus Inula were added to the genus Pentanema . There was a new combination to Pentanema hirtum (L.) D.Gut. Lousy. et al. in David Gutiérrez-Larruscain, Maria Santos-Vicente, Arne A. Anderberg Enrique Rico, M. Martínez-Ortega: Phylogeny of the Inula group (Asteraceae: Inuleae): evidence from nuclear and plastid genomes and a recircumscription of Pentanema. In: Taxon , Volume 67, Issue 1, March 2018 on page 159.

Others

Inula hirta occasionally forms hybrids with the willow-leaved elephant ( Inula salicifolia ).
