Selenicereus grandiflorus is a species in the genus selenicereus from the cactus family ( Cactaceae ). The specific epithet is derived grandiflorus grandis from the Latin words for ' big' and florus - for, - flowered ' and refers to the large flowers of the type common names are " Queen of the Night ", " Reina de la Noche " and " Queen of the Night ". The German Cactus Society and the Society of Austrian cactus friends and the Swiss Cactus grandiflorus selenicereus Society chose 2009 as the " cactus of the Year".

Description

Selenicereus grandiflorus growing spreizklimmend or climbing up to 5 meters long shoots, the diameter of 1 to 2.5 centimeters have. There are five to eight low ribs available. The areoles located on it are not raised or elevated and without numerous hair. The springing from them six to 18 whitish to brownish spines are bristle-like or occasionally finely acicular and pungent. You can reach lengths from 0.45 to 1.5 inches and fall off later.

The fragrant flowers are up to 30 centimeters in length and capable of just such diameter. Your outer bracts are yellow to brownish and narrow, the interior is white and wider. The spherical to ovoid fruits are pink to magenta and 8 inches long.

Distribution, systematics and hazard

Selenicereus grandiflorus is in the southeastern United States, distributed in Mexico and the Caribbean.

The first description as Cactus grandiflorus by Carl Linnaeus published Species Plantarum in 1753. Nathaniel Lord Britton and Joseph Nelson Rose set the style in 1909 in the genus selenicereus. A synonym is Cereus grandiflorus nomenklatorisches ( L.) Mill ( 1768).

We distinguish the following sub- types:

  • Selenicereus grandiflorus subsp. grandiflorus
  • Selenicereus grandiflorus subsp. lautneri Ralf Bauer

Selenicereus grandiflorus subsp. grandiflorus The subspecies has four to six ribs. It is the spread in the United States in the state of Florida, in the Mexican states of Tamaulipas and Veracruz, in the Bahamas, Cuba, the Dominican Republic, Haiti, Jamaica, Puerto Rico and the Virgin Islands at low altitudes. Synonyms are Cereus jalapaensis Vaupel (1913 ), Cereus paradisiacus Vaupel (1913 ), Cereus roseanus Vaupel (1913 ), Cereus Hallensis Weing. ex Borg (1937, nom. inval. ICBN Article 32.1c ) and Cereus Hallensis Weing. ex Borg (1951, nom. inval. ICBN article 36.1).

Selenicereus grandiflorus subsp. lautneri The first description of Selenicereus grandiflorus subsp. lautneri by Ralf Bauer was published in 2003. The subspecies has nine to eleven ribs. It is distributed in the Mexican state of Oaxaca on the Pacific coast at low altitudes.

In the Red List of Threatened Species IUCN, the type is known as " Least Concern ( LC) ," ie, than not led at risk.

Ingredients

In the plant, there are several medically active ingredients. The flowers of Selenicereus grandiflorus contain betacyans and about 1.5% flavonol glycosides. Eight glycosidated flavonoids could be detected: Narcissin (0.05 %), Cacticin (0.02 %), Rutin, hyperoside, Kaempferitrin, Grandi Florin, isorhamnetin -3-O - β - ( xylosyl ) - rutinoside and isorhamnetin -3-O - β - ( galactosyl ) - rutinoside. The shoots appear to have the same range of flavonoids. In addition, they contain the biogenic amines tyramine ( 0.3 % of dry matter ), N- methyltyramine and hordenine (N, N- Dimethyltyramin ). Other ingredients are slime, grease, wax and resinous glycosides.
