Vegetative characteristics

The ascending saxifrage is a biennial herbaceous plant that thrives as a winter annual . It reaches stature heights of rarely only 1 to 3, mostly 4 to 25 centimeters. It does not form runners and grows loosely. There are no non-flowering shoots. The above-ground parts of the plant are densely hairy with glands . The stem is erect, strong, multilayered, often reddish and simple or branched. The overwintering rosette leaves are crowded, wedge-shaped and have three to five teeth at the tip. The stem leaves are similar, but the upper ones have no teeth and are lanceolate .

Generative characteristics

The flowering period extends from June to August. The umbellate to capid inflorescence is compact and multi-flowered. The flower stalks are shorter than the flowers.

The hermaphrodite flowers are almost radially symmetrical and five-fold with a double flower envelope . The five upright sepals are ovate or triangular to oblong and at most half as long as the petals. The white, non-dotted petals are three-veined and rarely 2, usually 3 to 6 millimeters in length, obovate to obovate to lanceolate with a rounded to slightly edged upper end. Two carpels have become an under constant ovary grown. There are two free pens available.

A capsule fruit is formed.

The number of chromosomes is 2n = 22.

Locations

Systematics and distribution

The first publication of Saxifraga adscendens was in 1753 by Carl von Linné in Species Plantarum , 1, page 405.

Saxifraga adscendens belongs to the subsection Tridactylites from the section Saxifraga in the subgenus Saxifraga within the genus Saxifraga .

Saxifraga adscendens occurs in Europe in the Alps , the Pyrenees , the Apennines , the Balkan Peninsula , the Carpathians , the Caucasus , Scandinavia as well as the Baltic States and North America .

In 1999 there were at least four subspecies of Saxifraga adscendens :

Saxifraga adscendens L. subsp. adscendens
Saxifraga adscendens subsp. discolor (Velen.) Kuzmanov : It occurs only in Bulgaria and Greece .
Saxifraga adscendens subsp. oregonensis (Raf.) Bacigalupi : It occurs in western North America from Alaska to Colorado and rises in the Rocky Mountains to over 4000 meters. This splitting off of a subspecies is not recognized by the Flora of North America 2009.
Saxifraga adscendens subsp. parnassica (Boiss. & Heldr.) Hayek : It occurs only in Italy , Sicily , the former Yugoslavia , Albania , Bulgaria and Greece.
