Adenostyles ( Adenostyles ) is a genus in the subfamily of Asteroideae within the family of Compositae (Asteraceae). The German trivial name "Dost" comes from Old High German and describes plants with dense, floriferous inflorescences.
description
Vegetative characteristics
In Adenostyles TYPES is perennial herbaceous plants . The above-ground parts of the plant are hairy depending on the species - almost bald to white tomentose. The long-stemmed leaves are largely arranged in a basal rosette. Of the few alternate leaves on the stem, the blade of the uppermost is significantly reduced.
Generative characteristics
The cup-shaped partial inflorescences are arranged in an umbrella-shaped inflorescence . The flower heads are around 1 centimeter long and contain hermaphroditic, pink tubular flowers . In the two most widespread species, the gray alpine oyster ( Adenostyles alliariae ) and green alpine ostium ( Adenostyles alpina ), there are only two to five (rarely up to ten) tubular flowers in a flower head , whereas the white felted alpine ostium ( Adenostyles leucophylla ) that occurs in the western Alps contains up to 25 tubular flowers per cup.
Occurrence
Adenostyles species thrive in the mountains of southern and central Europe. The Central European species mostly thrive in stone rubble corridors, in tall herbaceous corridors or in mixed mountain forests. Adenostyles leucophylla , which still occurs at altitudes of 3000 meters in the canton of Valais , rises the highest .
Systematics and distribution
The genus Adenostyles was established by Alexandre Henri Gabriel de Cassini (1781-1832) in 1816. A synonym for Adenostyles Cass. is Cacalia L. nom. rej. The scientific generic name Adenostyles is derived from the Greek words aden for gland and stylos for stylus, because of the club-shaped papillae on the stylus, which are not actually glands.
The genus Adenostyles belongs to the tribe Senecioneae in the subfamily of Asteroideae within the family of Asteraceae .
