Nothoscordum

Nothoscordum bivalve

The Nothoscordum, sometimes called Bastard Bastard or leek flowers, form a genus in the subfamily of the leek plants ( Allioideae ). The genus name is derived from the Greek Nothoscordum: Notho wrong and scordum for garlic. The genus includes about 25 species.

Occurrence

The genus is native only in the New World. Most species are native to South America, some are also available in North America. In many countries they are invasive plants.

Description

Nothoscordum species are perennial herbaceous plants. The plants smell little or no garlic or onions. These geophytes form ovoid bulbs with a membranous sheath and many bulbils as outlasting. The leaves are usually present during the flowering period. The leaves are alternate and usually spirally arranged in a basal rosette. The sessile, simple, parallel venation leaves are linear and thready. The leaf margin is smooth.

The inflorescence stem is mostly hollow, sometimes solid. in some areas originally doldige inflorescences usually contains multiple blooms. The two membranous bracts protect the flowers in knospigen state. The upright flower stems are different ( 1-5 cm ) long. The hermaphrodite, radial symmetry blooms are triple and often fragrant. The most six, with some kinds eight ( except within the monocots ), almost the same multiform bracts are fused at their base to about one third their length Roehrig. The free areas of the bracts are often spread out in a star shape. The colors of the bracts range from white to yellow. There are two circles, each provided with three fertile stamens, they are among themselves freely, but adherent to the base of the bloom and not project them. The stamens are pfriemförmig and widened at their base. The three carpels are a superior ovaries adherent to some (up to twelve) ovules per ovary chamber. The thread-like style ends in a small scar. There are Septalnektarien available. Pollination is by insects ( entomophily ).

There are dreigelappte, membranous, lokulizidale capsule fruits formed, containing several seeds. The oily, black by Phytomelane seeds are angular, compressed to flat.

Use

In the genus Nothoscordum there are a few types of varieties that are beautiful ornamental plants for the garden.

The bulbs of Nothoscordum gracile be eaten raw or cooked; they serve as a garlic substitute. However, the plants smell of Nothoscordum gracile for injuries not like garlic or onions; this species is classified as an aggressive invasive plant.

System

Karl Sigismund Kunth published the genus Nothoscordum 1843 in Enumeratio Plantarum, 4, p 457 The genus belongs to the tribe Nothoscordum Ipheieae in the subfamily Gilliesioideae within the family of the leek family ( Alliaceae ). A synonym for Nothoscordum Kunth is Zoellnerallium Crosa.

Some species of the genus Nothoscordum be classified by some authors in the Ipheion belong to, for example Nothoscordum sellowianum or Nothoscordum dialystemon. Mostly the doldigen inflorescences of Nothoscordum species contain several flowers and the Ipheion species only one flower, but there are exceptions. Other genera in which some of the Nothoscordum types are classified: Milla, Tristagma, Brodiaea, Beauverdia.
