The Finkensame ( Neslia paniculata ) also Ackernüsschen called, is the only kind of plant genus Neslia within the family of the cabbage family (Brassicaceae). It is divided into two subspecies.
description
Vegetative characteristics
The finch seed is an annual herbaceous plant and reaches heights of about 15 to 80 centimeters. It forms a thin taproot . The stem grows upright and is mostly branched in the upper part. Stems like leaves have branched and simple hairs ( indument ). The leaves are lanceolate, the lower ones are petiolate, the upper ones with a deep arrow-shaped base.
Generative characteristics
The flowering period is mainly in June and July. The reichblütigen inflorescences are initially schirmtraubig and by extending the inflorescence axis to the fruit ripening traubig , are thus beginning the flowers close together and the fruits are relatively far apart. The flower stalks are usually upright and are fruiting about 6 to 13 millimeters long. The hermaphrodite flowers are fourfold. The four bald and yellowish green sepals are elongated-elliptical with a length of 1.5 to 2 millimeters with a blunt upper end. The four golden yellow petals are spatulate with a length of 2 to 3 millimeters with a blunt upper end. The pods are more or less spherical in shape, usually wider than long (in the case of Neslia paniculata subsp. Thracica as long as wide), with a diameter of about 1.5 to 3 millimeters and a reticulate, wrinkled surface.
In the subspecies Neslia paniculata subsp. paniculata , the chromosome number is 2n = 14.
Occurrence and endangerment
Neslia paniculata is probably native to the Southeast European to Central Asian steppe area. Neslia paniculata is a neophyte in the rest of Europe and in North Africa, Asia, North America and Australia .
The finch seed is widely distributed in Central Europe. The finch seed occurs in Germany, especially in the central and southern areas, scattered to fairly widespread. However, its stocks are clearly declining. It is very rarely found in the rest of the area. In Austria it is common in the Pannonian region , otherwise it is scattered or rarely found. The finch seed occurs rarely and sporadically in Switzerland.
The finch seed grows in Central Europe in cereal weed communities. In Central Europe it thrives mostly on warm, nutrient-rich and mostly calcareous, loamy soils . It is a clay pointer that roots up to 60 cm deep. In Central Europe it is a character species of the Sedo-Neslietum from the association of poppy fields (Caucalidion lappulae), but also occurs in societies of the association Aperion or Sisymbrion.
In the Red List of Endangered Plant Species in Germany, the finch seed was placed in category 3+ in 1996, i. H. endangered .
Systematics
The first publication took place under the name ( Basionym ) Myagrum paniculatum by Carl von Linné . The new combination to Neslia paniculata (L.) Desv. was published by Nicaise Auguste Desvaux . A synonym for Neslia Desv. is Vogelia Medik.
Neslia paniculata is the only species of the genus Neslia in the tribe Camelineae within the cruciferous family (Brassicaceae).
One can distinguish between two subspecies:
- Neslia paniculata (L.) Desv. subsp. paniculata
- Neslia paniculata subsp. thracica (Velen.) Bornm. (Syn .: Neslia apiculata C.A.Mey. , Vogelia apiculata (Camey) Vierh.. , Neslia paniculata subsp. Apiculata (C.Mey) Maire & Weiller. ): It occurs in southern and southwestern Europe.
