Krusten-Steinbrech ( German )

provided by wikipedia DE

Der Krusten-Steinbrech (Saxifraga crustata Vest; Syn.: Saxifraga incrustata (Vest) Vest) ist eine Pflanzenart aus der Gattung Steinbrech (Saxifraga) in der Familie der Steinbrechgewächse (Saxifragaceae).

Merkmale

Der Krusten-Steinbrech ist eine ausdauernde Pflanze, die Wuchshöhen von 10 bis 30 Zentimeter erreicht. Sie ähnelt dem Trauben-Steinbrech, ist aber zierlicher. Die Rosettenblätter sind 10 bis 60 Millimeter lang, 2 bis 3 Millimeter breit, lang, schmal-linealisch und verschmälern sich zum Grund hin. Sie sind langhaarig bewimpert, graugrün und häufig von einer Kalkkruste bedeckt. An der Spitze sind sie bogig nach außen gekrümmt. Der Blattrand ist undeutlich gekerbt und meist ganzrandig sowie dicht besetzt mit kalkausscheidenden Grübchen. Der Fruchtknoten ist nicht oberständig.

Blütezeit ist von Juni bis August.

Die Art hat die Chromosomenzahl 2n = 28.

Vorkommen

Der Krusten-Steinbrech ist ein Endemit der südöstlichen Kalkalpen, wo er östlich der Etsch bis Slowenien, Bosnien, der Herzegowina und Westserbien vorkommt. Er wächst in der montanen bis subalpinen Stufe an Kalkfelsen sowie auf offenen kalkreichen Böden in Höhenlagen von 300 bis 2800 Meter.

Saxifraga crustata

provided by wikipedia EN

Saxifraga crustata, the crusted-leaved saxifraga and silver saxifrage, as well as encrusted saxifrage, is an evergreen perennial plant species in the family Saxifragaceae,[3] native to the Eastern Alps.[4][5] This species was described by Austrian botanist Lorenz Chrysanth von Vest in 1804.[2]

Etymology

While the genus name refers to the plant's ability to erode and break rocks while growing and spreading around (hence saxum means "rock" and frangere is translated as "to break" from Latin), its species' name comes from the Latin term crustatus or "encrusted", referring to the plant's shiny green leaves that have their surface covered with drops of crusty lime, secreted from special pores, located on the leaf margins.[3]

Description

Saxifraga crustata is an evergreen and perennial plant species[3] that grows in dense mats of medium-sized plants and can reach from 12 to 24 centimetres of height.[4] Its narrow and linear leaves that are green and have silver glow are usually arranged into rosettes.[3]

Silver shine of leaves is a consequence of small amounts of lime, more precisely calcite (a common polymorph of calcium carbonate), which is secreted by the plant's leaf margins, where secreting pores consisting of hydathode tissue are located.[3][6][7] Similar calcium carbonate excretion is exhibited by many other Saxifraga species, but not all of them secrete calcite (some excrete vaterite, while a few species' excrement consists of both calcite and vaterite).[7]

Ordinary looking flowers have long yellowish-white to cream white petals[4] and are united into panicles, which represent the terminal end of an intensively red coloured stems that bear no leaves.[3] This plant species flowers between June and August.[8]

Distribution

Saxifraga crustata occurs in the European Alps, including in Slovenia, Austria, Croatia and Italy.[3] Populations of this plant species are found in the Dolomites[4] and the Dinarides, ranging from Slovenia to Montenegro.[5] In Slovenia Saxifraga crustata is a relatively common plant species that grows in the Alps, as well as Trnovo Forest Plateau and the Snežnik mountain plateau.[9]

This plant is classified as a chasmophyte species, with its habitat typically consisting of rock screes and similar surfaces.[10]
