Silene stenophylla

Silene stenophylla belongs to the genus Silene ( Silene ) and the carnation family ( Caryophyllaceae ). From placental tissue of stored since 30,000 years in Siberian permafrost unripe fruits of flowering plants have been pulled.

Description

Appearance and leaves

Silene stenophylla is a perennial, dense cushion plant. The numerous, erect, unbranched and hairless stems reach a stature height 5-22 centimeters. The numerous basal leaves are up to 1.5 inches long; they are long stalks with narrow linealischer to almost filiform, 1-2 mm wide, sparsely ciliated at the edge of the leaf blade. The three ( or four ) pairs of continuously arranged stem leaves are similar, but smaller, wider at the base and grow together with the opposite hand.

Inflorescence, flower and fruit

The flowers are usually solitary at the end of the stem or rare for two to the third (up to six ) in a grape -like, zymösen inflorescence on flower stalks 10-15 millimeters in length. The ciliated bracts are herbaceous and suddenly contracted from a broad base. The hairless, somewhat inflated, verwachsenblättrige calyx is bell-shaped to tubular and bell-shaped and reaches a length of 10 to 15 millimeters and a width of 5-9 mm. It is either bright overrun with markedly contrasting purple or brown veins or entirely purple. At the top of the cup ends in five alternating wide and narrow teeth. The widths of the teeth are wide ovoid and have a more or less broad rim skin, wherein the narrow, triangular teeth lacking this skin edge.

The five petals are either pure white and then sometimes have a pink or purple veins, or they are completely pink, purple or colored purple. They are 1.5 times longer than the calyx. The plate is split up more than half in two strikingly wide, inverted egg-shaped lobes. Kronschuppen missing. The egg-shaped capsule is 9 to 10 millimeters long. It stands on a 3 to 4 millimeters long, fluffy hairy Karpophor. The approximately 1.5 millimeters long, dark brown seeds are kidney-shaped and streaked on the surface.

Variability

Plants from the southern part of its range tend to have wider fan leaves to inflorescences with more flowers and brighter colored goblets.

Heyday

The flowering season lasts from July to August.

Chromosome number

The chromosome number is 2n = 24

Occurrence

Silene stenophylla has a large area in the Arctic and boreal Eastern Siberia, with scattered occurrences and larger gaps. It ranges from the Lena River in the west to the Chukchi Peninsula in the northeast and to the islands of Sakhalin and the Japanese Hokkaido to the south.

Silene stenophylla preferably grows on rather low lime documents. It settles dry, wind -exposed, in winter largely snow -free ground in treeless vegetation of low tundra and scree. It is often with dwarf willow ( Salix), with mountain avens ( Dryas octopetala ) and associated with lichen. Their height amplitude includes both the coast and mountainous areas.

Taxonomy

Silene stenophylla was first described in 1842 by Carl Friedrich von Ledebour. Within the genus Silene it is placed in the section Graminifoliae.
