Vegetative characteristics

Bertram species grow as branched, mostly upright, sometimes overhanging to lying, mostly annual , only Anacyclus pyrethrum as perennial , herbaceous plants .

The leaves are alternate and mostly distributed on the stem or rarely initially concentrated in a basal rosette. The leaves are stalked or sessile and usually one to three-part pinnate . The leaf blades are mostly flat and herbaceous; only in Anacyclus linearilobus are they fleshy. The leaf blades can be intensely hairy, with only simple hairs ( trichomes ), or even hairless.

Generative characteristics

Rarely individually ( Anacyclus nigellifolius ) or mostly in branched, zymous total inflorescences , some to many, each over a bract, stalked, cup-shaped individual inflorescences stand together. The brown or brownish-green bracts stand together in several rows . The inflorescence bases are flat or very short conical. There are always chaff leaves available. The flower heads usually contain a number of ray-flowers (= ray-flowers) and always many tubular-flowers (= disc-shaped flowers). The ray-florets are mostly female; in some species the only few ray florets are reduced and partially covered by the bracts. The petals of the ray florets are usually white to creamy white and in some species, an important species characteristic, with purple stripes on the underside. In Anacyclus monanthos and Anacyclus homogamos , all flowers are hermaphroditic. The hermaphroditic, fertile tubular flowers have light to bright yellow corolla tubes .

The mostly flattened achenes have two wing-like edges, which can be fully developed up to spiky ( Anacyclus monanthos ) frayed. A pappus is absent (for example in Anacyclus pyrethrum ) or, if present, it can consist of a narrow crown or scales that merge into the wing-like edges of the achenes.

Systematics and distribution

The generic name Anacyclus was first published in 1753 by Carl von Linné in Species Plantarum , 2, page 892. Type species is Anacyclus valentinus L. For the designation as "Bertram" see Perennial Bertram .

The genus Anacyclus is common in the Mediterranean region, especially from North Africa to the Middle East and Turkey .

There are 8 to 13 Anacyclus typologies:

No longer belongs to the genus:

  • Anacyclus australis Sieber ex Spreng. Cotula australis (Sieber ex Spreng.) Hook. f.

use

From Anacyclus pyrethrum , an ancient medicinal plant, especially the root has been used by the medical effects were studied. Few species are used as ornamental plants .

Some as a spice; they are used, for example, in the Villach church day soup .
