Corpuscularia lehmannii ( Almanca )

wikipedia DE tarafından sağlandı

Corpuscularia lehmannii ist eine Pflanzenart der Gattung Corpuscularia aus der Familie der Mittagsblumengewächse (Aizoaceae). Das Artepitheton lehmannii ehrt den deutschen Professor für Botanik in Hamburg Johann Georg Christian Lehmann.[1]

Beschreibung

Corpuscularia lehmannii wächst kissenförmig, besitzt eine Pfahlwurzel und bildet an niederliegenden Trieben zusätzlich einige Adventivwurzeln aus. Die zweikantigen Internodien sind länger als die dreieckigen, glauken Laubblätter. Ihr Kiel ist anfangs schief, die Blattspitze ist gerundet. An Langtrieben sind die Laubblätter in der Regel 20 bis 25 Millimeter lang und 8 bis 10 Millimeter breit und stehen entfernt voneinander. An Kurztrieben sind sie fast halbkugelförmig und nahezu ziegelartig angeordnet. Sie sind 12 bis 16 Millimeter lang sowie 6 bis 8 Millimeter breit und dick.

Die weißen bis strohfarbenen Kronblätter der Blüten werden zur Mitte hin länger. Die Kapselfrüchte sind an ihrer breit trichterförmigen Basis von Brakteolen umhüllt. Sie enthalten 0,9 bis 1 Millimeter lange und 0,6 bis 0,75 Millimeter breite Samen.

Systematik und Verbreitung

Corpuscularia lehmannii ist in der südafrikanischen Provinz Ostkap bei Port Elizabeth verbreitet. Sie wächst in Karooider Vegetation und in Felsspalten.

Die Erstbeschreibung der Art als Mesembryanthemum lehmannii durch Christian Friedrich Ecklon und Carl Ludwig Philipp Zeyher wurde 1837 veröffentlicht.[2] Gustav Schwantes stellte die Art 1926 in die Gattung Corpuscularia.[3]

Nomenklatorische Synonyme sind Delosperma lehmannii (Eckl. & Zeyh.) Graessn. (1934, nomen nudum) und Schonlandia lehmannii (Eckl. & Zeyh.) L.Bolus (1927). In die Art als Synonym einbezogen wurden Delosperma algoensis L.Bolus (1929) und Mesembryanthemum sexpartitum N.E.Br. (1908).

Delosperma lehmannii ( İngilizce )

wikipedia EN tarafından sağlandı

Delosperma lehmannii is a succulent plant native to parts of the Eastern Cape Province of South Africa.[1] Sometimes called ice plant, it is grown as a decorative houseplant for its distinctive smooth, angular leaves. The specific epithet lehmannii honors the German professor of botany in Hamburg Johann Georg Christian Lehmann.

Delosperma lehmannii grows in the eastern coastal strip of the Cape Peninsula over an area of about 70 km2 between Coega and Port Elizabeth.

It grows on quartz soils in the Karoo. It tolerates aridity well and temperatures down to -5 °. Densely leafy, it forms a cushion with a tap root and some additional adventitious roots on sprawling, prostrate stems.[2]

Although it has not yet been subjected to an evaluation by the IUCN, the South African National Biodiversity Institute (SANBI) has classified it as a species at extremely high risk of extinction in the wild. In 2006, of the six registered populations, four were extinct due to the urban expansion of Port Elizabeth; in one of the remaining sub-populations near Coega over 60% of the habitat had been lost to mining.[2]

Description

Delosperma lehmannii is a compact plant with glaucous leaves with a characteristic triangular section.

It has numerous short, decombing shoots. All parts are hairless. The leaves are forked, at 3 angles. Leaves on shoots up to 4 cm long (mostly 20–25 mm long) and 8–10 mm wide and spaced apart. The flowers are approximately 4 cm in diameter. Six sepals. Translucent white to straw-colored petals, decreasing in length towards the center. Capsules: 6-8 chambers. Seeds: 0.9–1 mm in length, 0.6–0.75 mm wide.

Delosperma lehmannii ( İtalyanca )

wikipedia IT tarafından sağlandı

Delosperma lehmannii (Eckl. & Zeyh.) Schwantes, 1926) è una pianta succulenta appartenente alla famiglia delle Aizoaceae, endemica delle province del Capo, in Sudafrica[1].

Descrizione

D. lehmannii è una pianta compatta, con foglie glauche dalla caratteristica sezione triangolare.

Fusto

Ha numerosi germogli corti decombenti. Tutte le parti sono glabre.

Foglie

Biforcate, a 3 angoli. Foglie su germogli lunghi fino a 4 cm (per lo più 20–25 mm di lunghezza) e 8–10 mm di larghezza e distanti tra loro. Ciglia oblique all'inizio, che dall'alto spuntano uniformemente verso l'apice acuto, più bruscamente di lato, ogni foglia con un germoglio corto sviluppato a 2 foglie all'ascella, non papilloso. Sui germogli corti le foglie sono da ovali a quasi globose e quasi imbricate, lunghe 12–16 mm, larghe 6–8 mm e spesse.

Fiori

Circa 4 cm di diametro in un timo peduncolato, a più fiori. Sei sepali. Petali da bianchi a paglierini traslucidi, di lunghezza decrescente verso il centro.

Frutti

Capsule: 6-8 camere. Semi: 0,9–1 mm di lunghezza, 0,6–0,75 mm di larghezza.

Distribuzione e habitat

C. lehmannii è una specie endemica del Sudafrica, diffusa nella fascia costiera orientale della penisola del Capo (Provincia del Capo orientale) su un'area di circa 70 km² tra Coega e Port Elizabeth.

Cresce su terreni quarzici, sopporta bene aridità e temperature fino a -5°. Densamente frondosa, forma un cuscino con una radice a fittone e alcune radici avventizie aggiuntive su steli tentacolari e prostrati[2].

Conservazione

Benché non sia ancora stata sottoposta ad una valutazione dell'IUCN, per il South African National Biodiversity Institute (SANBI) è da classificare come una specie a rischio estremamente alto di estinzione in natura[2]. Difatti nel 2006, delle sei popolazioni registrate, quattro risultavano estinte per l'espansione urbana di Port Elizabeth; in una delle rimanenti subpopolazioni vicino a Coega oltre il 60% dell'habitat era andato perduto per attività minerarie.
