The laciniate cranesbill ( Geranium dissectum ) is an annual plant from the family of geraniaceae .

description

The slit-leaved cranesbill is usually an annual , more rarely a biennial plant . It has a taproot and reaches heights of 10 to 40, rarely 60 cm. The stems are ascending to erect and branched. Like the petioles, they are covered with backward-facing, protruding hairs that are 0.5 to 1 mm long and occasionally glandular.

The rosette of the basal leaf is usually already dried up before flowering. The stem leaves are opposite, their petiole 1 to 9 (rarely 13) cm long. The leaf blade is 2 to 4 (rarely up to 9) cm wide and five to seven-lobed almost to the base. The sections are two to four columns. The stipules are lanceolate and pointed.

The partial inflorescences are two-flowered and have 0.5 to 3 (rarely 5) cm long stems, which are usually shorter than the bracts. The flower stalks are 0.5 to 1.5 cm long. Both stalks and the sepals are densely covered with glandular hairs 0.2 to 0.8 mm long. The flowers are small with a maximum diameter of 1.5 cm. The sepals are 5 to 8 mm long, carry a 0.5 to 1.5 mm long awn , which elongates at the fruiting time. The petals are 5 to 6 (rarely 8) mm long, of red-violet color. They are edged or incised at the tip, the nail is hairy. The stamens are maximally as long as the petals.

The fruit is a desiccant spreader . It is hairy glandular, including beak (13 to) 15 to 18 mm long. The fruit flaps are 3 mm long, the fruit beak 7 to 12 mm. The seeds are smooth and dotted with pits.

The number of chromosomes is 2n = 22.

  • Habitus

  • The leaves are divided almost to the bottom. The foliage leaf sections have tips that spread apart.

  • Post-floral inflorescence

  • blossom

  • The flower stalks are covered with protruding glandular hairs.

  • The sepals have an awn.

  • Fruit with a hairy beak.

  • The fruit flaps are also hairy.

Distribution and locations

The slit-leaved cranesbill is native to Europe and is also found in western Asia. Its area is meridional to temperate and oceanic. In Central Europe it is an archaeophyte , in Germany it is widespread, but rarely in the north.

It grows in fields, on roadsides and in gardens. In Central Europe it occurs particularly on fresh to moderately dry, nutrient-rich loamy soils. It is a decidedly clay pointer. It is a Fumario-Euphorbion-Verband character type in Central Europe .

It grows from the Kollinen to the montane altitude , in Upper Austria it rises to around 1000 m. In the Allgäu Alps, it rises in Bavaria in the Hintersteiner Tal near the gable house to 1200 m above sea level.
