Cyclamen rohlfsianum ( İngilizce )

wikipedia EN tarafından sağlandı

Cyclamen rohlfsianum is a species of perennial plant in the family Primulaceae.[2] It is endemic to Libya.[1] It grows from a tuber in shrubland, especially in limestone cracks, up to 450 m (1,500 ft) above sea level. It is one of the tenderest cyclamen species. The plant was discovered by Friedrich Gerhard Rohlfs in 1879, and was named after him in 1897 by Paul Friedrich August Ascherson.

Description

Its tubers are round when young, but become irregular with age, with multiple growing points across the surface of the tuber.[3] Cyclamen purpurascens also has irregular older tubers. Its leaves are large, with pointed lobes and prominent ribs, and wider than long. Leaves of Cyclamen hederifolium often have lobes, but are usually longer than wide. its flowers bloom in autumn with the young leaves and have 5 upswept petals, light pink with a darker nose. The stamens and pistil project below the nose, suggesting the shooting stars (Dodecatheon), but unlike any other cyclamen.

Cultivation

Cyclamen rohlfsianum has a longer summer dormancy than many other cyclamen species and flowers best after a hot, sunny summer. In this way it is similar to Cyclamen graecum and Cyclamen africanum.

Cyclamen rohlfsianum ( Fransızca )

wikipedia FR tarafından sağlandı

Cyclamen rohlfsianum Asch. – du nom l'explorateur allemand, Friedrich Gerhard Rohlfs, qui l’a découvert au XIXe siècle – est endémique dans un petit secteur de la Cyrénaïque en Libye, où il pousse dans les anfractuosités des rochers.

Description

Fleurs de Cyclamen rohlfsianum

Les fleurs odorantes, qui apparaissent à la fin de l’été, se reconnaissent à leurs étamines exsertes – comme celles de la gyroselle de Virginie (Dodecatheon meadia).

Une autre particularité à signaler : tandis qu’après fécondation, le pédoncule floral de la plupart des espèces se tord en tire-bouchon à partir du sommet, celui du cyclamen de Rohlfs le fait à partir de la base.

En novembre 2000, un premier exemplaire à fleurs blanches (f. album) a été obtenu en culture.

Les feuilles arrondies à grandes dents triangulaires, qui apparaissent après les premières fleurs, sont souvent marbrées.

Cyclamen rohlfsianum est le moins rustique des cyclamens actuellement en culture et doit être cultivée en serre froide.

Rohlfsova ciklama (lat. Cyclamen rohlfsianum) je vrsta višegodišnje biljke iz roda ciklama.

Rasprostranjenost i stanište

Rohlfsova ciklama je rasprostranjena na relativno malenom području na sjeveroistoku Libije, između Benghazija i Darnaha u regiji Cirenaika. Živi na nadmorskoj visini do 450 metara u području makije, na tlu crvenici, često ispod različitih grmova.

Opis

Listovi se pojavljuju u kasno ljeto, i oblika su bubrega. Gornja površina lista je sjajno svjetlozelena, ponekad na sebi ima srebrne šare, dok je donja površina najčešće ljubičasta ili crvenkasta. Dugi su 3.5-11.5 centimetara, a široki su 4.5-15.5 centimetara. Cvjetovi su slatkastog mirisa, pojavljuju se kad i listovi, ponekad malo prije njih. Sastavljeni su od pet latica ovalnog oblika, koja su duge 1.1-2.6 centimetara. Boja im je svjetloružičasta.

Cyclamen rohlfsianum ( Felemenkçe; Flemish )

wikipedia NL tarafından sağlandı

Cyclamen rohlfsianum – de naam komt van de Duitse ontdekkingsreiziger Friedrich Gerhard Rohlfs[1], die de plant in de 19e eeuw ontdekte – is oorspronkelijk afkomstig uit een deelgebiedje van Cyrenaica in Libië, waar de plant groeit in de rotsspleten.

Bloemen van Cyclamen rohlfsianum met de uitstekende meeldraden

Kenmerken

De geurende bloemen, die op het einde van de zomer uitkomen, zijn herkenbaar door hun duidelijk uitstekende meeldraden zoals die van het twaalfgodenkruid (Dodecatheon meadia).

Een andere bijzonderheid: terwijl bij de meeste soorten de bloemsteel zich na de bevruchting oprolt als een kurkentrekker vanaf de top van de steel, gebeurt dit bij Cyclamen rohlfsianum vanaf de basis.

In november 2000 werd voor het eerst een exemplaar met witte bloemen gekweekt (f. album)[2].

De afgeronde bladeren met grote, driehoekige tanden verschijnen na de eerste bloemen en hebben vaak een mooie tekening.

Kweek

Cyclamen rohlfsianum is de minst winterharde van de gekweekte cyclamen en moet dus in koude kas worden geplant.
