description
Vegetative characteristics
The Christ's eye elephant is a perennial herbaceous plant that usually reaches heights of 20 to 50 centimeters. The leafy stem is loosely tomentose. The leaf blades have a whole to serrated edge, are pinnate, tightly fitting silky-haired on both sides, glandular and aromatic. The basal leaves and the lower stem leaves have an obscure to lanceolate shape, are about 2 to 4.5 centimeters wide, gradually narrowing into the petiole and remain green until the anthesis .
Generative characteristics
The flowering period in Central Europe extends from June to August . The stem has 1 to 5 baskets and the baskets have a diameter of 25 to 50 millimeters. The bracts are tiled-roofed in several rows. The outer bracts are 0.5 to 3.5 millimeters wide, the inner ones lie upright and are shorter than these.
While tubular flowers are arranged in tight spirals on the inside of the basket base , on the outside there are ray florets with golden-yellow, 3–30 millimeter long tongues, which protrude far beyond the shell. The achenes are usually 2 to 2.5 millimeters long and hairy.
Chromosome number
The number of chromosomes is 2n = 16 or 32.
ecology
The Christ eye elephant is a hemicryptophyte .
Occurrence and endangerment
In Europe, the Christ-eye elephant is native to Central , Southeastern and Eastern Europe, in the United Kingdom it appears as a new citizen . In the German-speaking area, the species occurs only in Austria .
