The coastal beach star ( Pallenis maritima ), also called ducat flower, is a species of the genus Pallenis in the sunflower family (Asteraceae).
description
The coastal beach star is a perennial plant or dwarf shrub that reaches heights of growth of (2) 5 to 40 centimeters. The plant is bushy, but there are no branches directly under the heads. The leaves are obovate, elongated, single-veined, thick and humped, bristly, rough. The flower heads are 3 to 3.5 centimeters in diameter. The bracts are as long as the golden-yellow ray-flowers and have spoon-shaped ends.
Flowering time is from August to September, sometimes it begins as early as April.
The chromosome number is 2n = 12.
Occurrence
The coastal beach star occurs in the western and central Mediterranean area and in Greece on coastal rocks. Its distribution area includes Morocco, Algeria, Tunisia, Spain with the Balearic Islands and Gibraltar, Portugal, France, Italy, Corsica, Sardinia and Sicily and Greece.
Systematics
The coastal beach star was first described by Carl von Linné in 1753 as Buphthalmum maritimum . In 1832 Christian Friedrich Lessing set it up as Asteriscus maritimus . As part of the nomenclature revision of the genus by Werner Greuter in 1997, it was then transferred to the genus Pallenis together with other species . Later molecular biological investigations confirmed this classification. Pallenis hierichuntica is considered to be closely related .
The coastal beach star ( Pallenis maritima (L.) Greuter ) has the synonyms: Buphthalmum maritimum L. , Asteriscus maritimus (L.) Less. , Bubonium maritimum (L.) Hill , Odontospermum maritimum (L.) Sch. Gdp. , Asteriscus littoralis Jord. & Fourr. and Asteriscus mauritanicus Jord. & Fourr.
use
The coastal beach star is used as an ornamental plant in window boxes, hanging baskets and summer borders. The species has probably been in culture since 1900. The 'Gold Coin' variety has sterile flowers.
