The five sepals 4 to 6 mm long, pointed and whitish with two green central stripes. The five petals are significantly shorter than the sepals. There are three styluses. The three-lobed capsule fruit is shorter than the sepals.

The number of chromosomes is 2n = 26 or 30.

Occurrence

The Büschel-Miere is a sub-Mediterranean species. Its distribution area includes the Pyrenees, France, Northern Italy, Switzerland to the Upper Rhine area, Austria, Hungary, Romania, Yugoslavia. It does not occur outside of Europe. The occurrences in Germany represent the northern rather than the western border of their area.

In Austria, the Büschel-Miere occurs in the federal states of Vienna, Lower Austria, Burgenland and Salzburg scattered or rarely in the colline to submontane altitude range . The species became extinct in Upper Austria. The occurrences concentrate on the Pannonian . The Büschel-Miere is considered endangered in Austria, in the northern foothills of the Alps as endangered.

The Büschel-Miere needs calcareous, even lime-rich, dry, warm, stony and loose soil that is warm in summer, which should be poor in nitrogen, and which can also be sandy or loamy. It settles in climatically favorable areas (Upper Rhine Valley, wine-growing area between Neustadt an der Weinstrasse and Mainz, Franconian Jura near Regensburg, Upper Bavaria, Swiss Jura between Lake Biel and Geneva, Valais, Ticino), gappy dry grassland and rocky slopes. It is very rare in the areas already mentioned. It is a character species of the Cerastietum pumili from the Alysso-Sedion association, but also occurs in the Xerobrometum.
