Generative characteristics

The heady racemose inflorescence is not or barely longer than wide and contains 3 to 15 flowers. The bracts do not protrude from the calyx. The flowers are clearly (short) stalked.

The flowering period extends from June to August. The hermaphrodite flowers are zygomorphic with a double flower envelope . The calyx is 8 to 9 millimeters long and is usually ciliate and hairy on the longitudinal nerves, otherwise bald. The calyx-lobes, which are turned back at the tip, are about half as long as the calyx-tube. The mostly dark purple crown is 16 to 25 millimeters long and two-lipped. The upper lip bill is 3 to 5 millimeters long.

The number of chromosomes is 2n = 16.

ecology

In terms of flower ecology, the heady louse herb is a bumblebee flower .

Occurrence

The distribution area includes the Eastern Alps , Carpathians and the Northern Balkans . This limestone species prefers stony lawns at altitudes between 1200 and 2700 meters. In the Allgäu Alps, it comes from 800 meters in the valley up to an altitude of 2400 meters. It is a character species of the association Seslerion albicantis and occurs mainly in the Caricetum firmae and in the Seslerio-Caricetum sempervirentis.

In Austria this species is common in the alpine altitudes , it is absent in Vienna and Burgenland.
