Yellow bog lily ( Narthecium ossifragum )

Narthecium, called in German bog lilies, bog asphodel, Ährenrinsen or ears of corn lily, is a genus in the family of Nartheciaceae. The approximately seven species possess a disjoint area on the northern hemisphere.

Description

Vegetative characteristics

Narthecium species grow as perennial herbaceous plants reach stature heights of 10 to 50 cm. These geophytes form creeping rhizomes than outlasting. The sticky stem is stiff and upright, he is underground further and there has a slight fiber mop. The three to six undergraduate leaves are sword-shaped.

Generative features

On upright, leafy Blütenstandsschäften are the terminal, loose, racemose inflorescences. The blooms are triple. The six identically shaped bracts ( tepals ) are largely free and yellow to greenish yellow. The white stamens are densely hairy fluffy, the anthers are linear. Three carpels are fused to a dreikammerigen, superior ovaries.

Are formed thin-walled ovoid to lanceolate - ovate, insulated draft tube capsule fruits. The bright yellow, filiform - ellipsoidal seeds is truant at both ends.

The basic chromosome number is x = 13

Ingredients

They are toxic by the saponin Narthecin, it is a liver poison.

Systematics and distribution

The genus Narthecium has a strongly disjoint area: with three species in Europe, a kind in the Middle East, of a species in East Asia and two species in North America.

The genus Narthecium was formerly classified in the family Liliaceae, or the Melanthiaceae. The first publication of the genus Narthecium was in 1762 by William Hudson in Flora Anglica, p 127 type species is Narthecium ossifragum (L.) Huds .. A synonym for Narthecium Huds. Abama is Adans .. The scientific name derives from the Greek word for narthex rod from, this is the inflorescence form justified.

In the World Checklist of Nartheciaceae ( Kew ), the following seven species are recognized:

• Narthecium americanum Ker Gawl. ( Syn: Abama americana ( Ker-Gawl. ) Morong, Abama montana Small, Narthecium ossifragum var americanum ( Ker-Gawl. ) Gray ): It occurs on the east coast of North America.
• Narthecium asiaticum Maxim. It occurs in northern and central Japan.
• Narthecium balansae Briq. It occurs in the north-eastern Turkey and western Caucasus.
• Narthecium californicum Baker: It occurs on the west coast of North America.
• Bog asphodel, bog Yellow lily, bog ears lily ( Narthecium ossifragum (L.) Huds, Syn. Anthericum ossifragum L.): It occurs in Western Europe.
• Narthecium reverchonii Čelak. The home is Corsica.
• Narthecium scardicum Kosanin: It comes from northeastern Albania prior to northwestern Greece.
