description
Vegetative characteristics
The Apennine thistle is a perennial herbaceous plant that reaches heights of about 40 centimeters. The stem, which is branched into several side branches, is hairy with cobwebs and broadly prickly winged in the lower part. The lobed, thorny foliage leaves are glabrous or only slightly hairy on top, and densely spider-weby and woolly on the underside. The leaf lobes are drawn out into a thorn up to 5 millimeters long.
Generative characteristics
The flowering period extends from June to August. At the end of a very short or no more than 6 centimeters long unleaved stem section there is a cup-shaped inflorescence with a diameter of 4 to 6 centimeters. The outer and middle bracts are drawn out in a laterally protruding or folded back long spine. The tubular flowers are purple in color.
The achenes have a pappus.
Occurrence
The Apennine thistle occurs in the mountainous landscapes of the Mediterranean in Italy and Croatia up to an altitude of 2300 meters above sea level. It inhabits dry pastureland and rocky locations.
Systematics
