The marsh bedstraw ( Galium palustre ) is a plant from the genus of Galium ( Galium ) in the family of the Rubiaceae (Rubiaceae).

description

illustration

The marsh bedstraw is a hibernating green, perennial herbaceous plant that usually reaches heights of 8 to 30, rarely up to 150 cm. The thin stems are somewhat rough due to downwardly directed prickly trichomes , and only rarely are they smooth. The leaves are rounded. The middle leaves are 5 to 15 mm long.

The flowering time is between May and July or September, depending on the location. The inflorescences are loose, the partial inflorescences are profuse. The hermaphrodite flowers are fourfold. The usually four-lobed, white crown has a diameter of 2 to 3.5 mm. The red anthers are particularly characteristic .

The fruits, which stand on straight fruit stalks, are fine-grained, rough.

The number of chromosomes is 2n = 24.

Possible confusion

The marsh bedstraw can easily be confused with the tall bedstraw ( Galium elongatum ). Some authors also summarize both species as subspecies of a species, which is then given the scientific name Galium palustre L. s. l. wearing. You can distinguish the marsh bedstraw by its non-white-edged stem and its flowers, which are no more than 4 millimeters wide. Its chromosome number is also 2n = 24, while the high bedstraw has the number 2n = 96.

ecology

The marsh bedstraw is a hemicryptophyte . The flowers are pre-male. Spontaneous self-pollination is possible.

Occurrence

The distribution area of ​​the marsh bedstraw extends from Europe to western Siberia, from Greenland to Maryland and includes the Azores and northwestern Africa. The marsh bedstraw thrives from the colline to montane or high-montane altitudes at altitudes of up to 1850 meters, for example in the pond at the Seehütte at the northwest foot of the Kleiner Rappenkopf in the Allgäu Alps in Bavaria. It grows in wet meadows, large sedge areas, reed beds, banks, ditches and light wet forests. The preferred soils are wet, partially flooded, moderately nutrient-rich clay and swamp humus soils. In Central Europe it is a character species of the Magnocaricion association.

The marsh bedstraw is common in all Austrian federal states.
