Inflorescences

Vegetative characteristics

The knot-flowered celery grows as a deciduous, perennial herbaceous plant and usually reaches heights of 30 to 60 (10 to 100) centimeters. The prostrate or arching stalk can form roots at its base, is bare and smells aromatic when rubbed.

The simple pinnate leaves are ovate to lanceolate in outline with evenly notched leaf sections.

Generative characteristics

Opposite to the leaf there are sessile to short-stalked double- gold inflorescences that contain many flowers. The inflorescence has 3 to 15 umbel rays. There are no or two bracts. The four to six husk leaves have a white skin edge. The flowers are five-fold.

The gap fruit is longer at a length of 1.5 to 2.5 millimeters than wide.

The number of chromosomes is 2n = 22.

ecology

The knotty celery is a helomorphic hydrophyte and hemicryptophyte .

Insect pollination and self-pollination occur.

Occurrence and endangerment

The original distribution area of the knotty celery includes the Mediterranean area , Europe and Asia . In addition to Europe, these include the Azores, Madeira, North Africa, Ethiopia, Yemen, West and Central Asia and Pakistan. It is a neophyte in Argentina, Chile, California, New Jersey, South Carolina, and New Zealand. In the Canary Islands, the originality is doubtful.

It occurs in Germany scattered in Baden-Württemberg , Hesse and Rhineland-Palatinate . He can also be found in North Rhine-Westphalia , albeit rarely. In the past there was another population in Bienitz near Leipzig in Saxony . In Germany, the knotted celery was rated endangered in 1996.

The knot-flowered celery prefers wet, nutrient-rich, often salty ditches and reed borders of streams. It is a character species of Apietum nodiflori from the Sparganio-Glycerion Association.

Taxonomy

It was first published in 1753 under the name ( Basionym ) Sium nodiflorum by Carl von Linné in Species Plantarum . The new combination to Helosciadium nodiflorum (L.) WDJ Koch was published by Wilhelm Daniel Joseph Koch . Another synonym for Helosciadium nodiflorum (L.) WDJ Koch is Apium nodiflorum (L.) Lag.

Common names

For this type of plant there are or were, in some cases only regionally, the common names Bachhopfen (Henneberg), Resepastinak, Scheibering, Sumpfschirm ( Westphalia ), Kleine Wassermerk and Wassermorellen.
