Ixiolirion

Ixiolirion tataricum

Ixiolirion, sometimes also called Steppe flowers, mountain lilies or blue lily, is the only genus of the mono- generic family of Ixioliriaceae in the order of the asparagus -like ( Asparagales ) within the monocot plants. There are approximately four species in the genus, and thus family. The species have areas of Egypt to Central Asia and the south-western Asia. They are rarely used as ornamental plants.

Description

Habit and foliage leaves

Ixiolirion species grow as upright, perennial herbaceous plants reach the stature heights of up to 50 cm. They form ( onion-shaped ) tubers as outlasting that of a membranous sheath ( tunic ) are surrounded.

The more or less pronounced in basal rosettes standing together, alternate and spirally arranged leaves are sessile and easy. The flat leaf blade is linear or lanceolate and parallel-veined. The leaf margin is smooth.

Inflorescences and flowers

In terminal, from doldigen, paniculate or racemose inflorescences part composite total inflorescences are often only a few flowers together. Bracts may be present or absent.

The stalked, large, funnel-shaped, radial symmetry flowers are hermaphroditic and threefold. The six bracts ( tepals ) are arranged in two circles and not or at most short- fused at their base. The bloom of the outer circle are usually narrower than that of the inner. The colors of the bracts range from almost white to purple and blue. There are two circles, each with three fertile stamens present; they are among themselves freely but adherent to the base of the bloom. The two-celled pollen grains have an aperture and are sulcat. The three carpels are to a predominantly inferior ovary fused with 15 to 50 ovules per ovary chamber. The stylus, which is much longer than the ovary, ending in a three-lobed stigma. There are nectaries present.

Fruits, seeds and seedlings

The dreikammerigen capsule fruits contain many seeds. The small, angular seeds are black by Phytomelane. Well-trained embryo is almost as long as the endosperm. The cotyledon remains white even under the influence of light.

Ingredients and chromosome numbers

In contrast to the Amaryllidaceae alkaloids are not, not even in the blue flowers available. There are mucilage cells present. The chromosome number is n = 12

Systematics and distribution

The range extends from Egypt and Turkey to Central Asia and the south-western Asia. They thrive in temperate areas and in the western Himalayas.

The first publication of the genus was made in 1821 by Friedrich Ixiolirion Ernst Ludwig von Fischer in William Herbert: Bot Reg, An Appendix Bot Reg, 37 A synonym for Ixiolirion Herb. is Kolpakowskia rule. The Ixioliriaceae ( Pax ) Nakai family was released on July 20, 1943 by Nakai Takenoshin in Chosakuronbun Mokuroku, 234.

The genus Ixiolirion was formerly in the family of Amaryllidaceae J.St. - Hil. classified. The family of Ixioliriaceae ( Pax ) Nakai is the Alliaceae Batsch ex Borkh. and particularly the Tecophilaeaceae Leybold close.

In the genus Ixiolirion there are about ( a to) four ways:

  • Ixiolirion ferganicum Kovalevsk. & Vved. Home is Central Asia.
  • Ixiolirion karateginum Lipsky: The home is Central Asia and northeastern Pakistan.
  • Ixiolirion songaricum P.Yan: This species occurs on dry slopes and fields at altitude 400-1600 meters only in the northeastern China. It is endemic to the province of Xinjiang Tianshan Gegirge.
  • Mountain Blue Mountain Lily or Amaryllis ( Ixiolirion tataricum ( Pall. ) Herb, Syn. Amaryllis tatarica Pall, Amaryllis montana Labill, Ixiolirion montanum ( Labill. ) Herb, Ixiolirion pallasii Fish & CAMey ex Ledeb. .. .. . ): The home ranges of eastern Turkey to Kashmir: with two varieties: Ixiolirion tataricum var ixiolirioides ( usually ) XHQian: The home ranges of Central Asia into northern Xinjiang.
  • Ixiolirion tataricum ( Pall. ) Herb. var tataricum
