Scientific name
Erigeron
L.

The erigeron ( Erigeron ) constitute a genus within the family of Compositae (Asteraceae). The almost worldwide up to 400 species are mainly distributed in the temperate areas of the northern hemisphere ( Holarctic ) and especially in North America (173 species). Only nine species are native to Central Europe.

Appearance and leaves

Erigeron species are annual or perennial herbaceous plants , some species are evergreen. The stems are erect or prostrate. The leaves are always alternate , in many species the leaves are in a basal rosette. The leaf blades are whole, toothed to divided.

Inflorescences, flowers and fruits

The flower heads stand individually or to a few, rarely to several. The diameter of the flower heads is 5 to 35 millimeters. The bracts are in two or three series, narrow and herbaceous to dry. The bottom of the basket is flat or convex and bare. The occupational herbs have tubular and ray flowers . On the outside, in one or more rows, the rarely missing, mostly 12 to 350 ray-flowers (= ray-flowers) are white to red-brownish in color and almost twice as long as the tubular flowers and spread outwards; they are feminine and fertile . The 25 to 450 tubular flowers (= disc flowers) are hermaphroditic, fertile. There are usually much more disc flowers than ray flowers. The corolla tube is usually yellow and the five corolla lobes are sometimes purple.

The achenes are mostly narrow ellipsoidal to ovoid, sometimes compressed. The pappus is usually double, the outer row usually scaly or missing, the inner row fine. Very rarely the pappus is completely absent.

Sets of chromosomes

The basic chromosome number is x = 9. In the genus Erigeron is polyploidy often, often accompanied by Agamospermy , especially in species with odd-ploidy.

Differences between Conyza and Erigeron

The distinguishing features between the two genera, which are known as “professional herbs” and have often been combined under Erigeron since the results of molecular genetic studies, are not always clear. Usually Conyza has asymmetrical bracts and 2 to 20 times as many female as hermaphrodite flowers in each cup, rarely more hermaphroditic than female. The crown of the female flowers usually have no tongue or it is at least shorter than a millimeter. The genus Erigeron has approximately symmetrical bracts and more hermaphroditic than female flowers. The crown of the female flowers usually has a tongue 2 to over 10 millimeters in length.

Plant diseases

Various types of Erigeron are attacked by the rust fungi Puccinia cnici-oleracei and Puccinia dovrensis .

Systematics and distribution

The genus Erigeron was in 1753 by Linnaeus in Species Plantarum erected . The botanical genus name Erigeron is made up of the Greek words eri for "early" or erio for "woolly" and geron for "old man" and refers to the "white hair" of the fruits that appears soon after the flowering period . Synonyms for Erigeron L. are: Achaetogeron A. Gray , Trimorpha Cass.

Depending on the source, the genus Erigeron (200 to) 390, if the genus Conyza is included, contains up to 400 species. The high and strongly fluctuating numbers are typical for agamosperm clans . According to molecular genetic studies, the genus is likely to be paraphyletic , as the genera Conyza (25 to 60 species), Aphanostephus (four species) and the South American Leptostelma group are within the monophyletic group of Conyzinae .

Some varieties are used as ornamental plants . They mostly prefer sheltered, sandy locations.

Origin of name

The German common name berufkraut is not derived from occupation , but from occupation (also screaming or screaming, for bewitching). If illnesses occurred that were caused by sorcerers and witches of black magic, ablutions were carried out with a brew of erigeron and medicinal herbs or the illness was "transmitted" to the plants by a spell. Other "professional herbs" are for example the toadflax ( Linaria vulgaris ), the swamp yarrow ( Achillea ptarmica ), the upright seaweed ( Stachys recta ), the St. Christopher's herb ( Actea spicata ), the ragwort ( Senecio vulgaris ), the wound clover ( Anthyllis vulneraria ) and the tansy ( Tanacetum vulgare ).
