The delicate chess flower ( Fritillaria messanensis subsp. Gracilis ) is an endemic species of the Dinarides from the lily family (Liliaceae). It is a subspecies of F. messanensis that is also widespread in Italy. The delicate chess flower is a warmth-loving species of the Mediterranean, which is widespread from 600 to 1700 m altitude. The higher the location, the more the typical color with green stripes on the back is given. The deeper occurrences are monochrome.
description
Stems with 7 to 10 linear leaves, the lowest 4 to 9 cm long and 3 to 7 mm wide, often opposite, the others alternate or the uppermost in the whorl nodding to 3rd flowers, broadly bell-shaped, the bracts 22 to 32 mm long, faded checkerboard pattern, purple pattern on the back with a green border. The checkerboard flower forms angular seed pods with numerous seeds. These are brown, thin, approx. 4 to 5 mm long and approx. 2.5 to 3 mm thick, predominantly irregularly triangular or trapezoidal.
The chess flower is a pre-summer green geophyte and grows from an onion . From early spring it forms a stalk between 15 and 30 (-40) cm long and covered with four to five narrow, channeled, gray-green leaves. Bell-shaped, downward-hanging flowers develop on it from May to June. These are checkerboard-like purple with greenish-white stripes.
The number of chromosomes is 2n = 24.
distribution
The delicate chess flower is endemic to the Dinarides . It is widespread from Croatia via Bosnia, Montenegro to northern Albania. Locations are moderately steep limestone sites on humus Rendzina .
ecology
The delicate chess flower is a warmth-loving plant of light downy oak forests on limestone soils, but also occurs in the oromediterranean Dinaric karst block dump fir forest and snake skin pine rock forest. It is a characteristic plant of the littoral snake skin pine forest in the Orjen Mountains.
Danger
As an endemic species, it is restricted to the Dinarides ( Orjen , Velebit , Prokletije ) and there in small groups mostly local but sometimes more common. It is a Red List plant in Croatia and is classified under VU (endangered).
