Alstroemeriaceae

Alstroemeria aurea in Chile

The Inca Lily Family ( Alstroemeriaceae ) are a family of plants within the order of the lily -like ( Liliales ). The family now includes two tribes with four genera and about 170 species.

Description

Habitus and sheets

There are perennial herbaceous plants with rhizomes or tubers as outlasting or at the Luzuriageae more or less woody plants in the Alstroemerieae. There are some species that are climbing plants. The alternate or spirally at the Alstroemerieae or two lines at the Luzuriageae, but never rosette leaves are arranged resupinat as a special feature for this family, so the leaf blade is rotated approximately 180 degrees. The stalked, relatively large leaves have a simple, flat, parallel-veined, linear to lanceolate leaf blade. The lower leaf surface is turned upward and the blade edge is smooth.

Inflorescences, flowers and fruits

The flowers are single or in axillary or terminal, racemose or doldigen inflorescences ( inflorescences ) with leaf -like bracts. The hermaphrodite, radial symmetry ( Luzuriageae ) to mostly zygomorphic ( Alstroemerieae ) blooms are triple. The bloom are alike, so there are (2 × 3) six or deformed largely free tepals, in the Alstroemerieae green, orange, red or pink and may be at Luzuriageae they are white. At the lower end of the tepals nectar is secreted. There are two circles, each with three free stamens. Three carpels are under a constant Alstroemerieae at or above standing at Luzuriageae ovary adherent to many ovules in most parietal placentation.

The flowers formula is: or or or

They form seed capsules or sometimes berries. The Testa is thin.

Systematics and distribution

Barthélemy Charles Joseph Dumortier introduced in 1829, the family of Alstroemeriaceae as part of the " Iridarieae " on. With the genus Alstroemeria Alstroemeria salsilla by Carolus Linnaeus in 1762 was placed in Plantation alstroemeria and he named it in honor of his students Alstroemer Claus ( 1736-1794 ); it is the type genus of the family.

The molecular genetic studies in the last ten years have meant that the family boundaries within the order of the lily -like ( Liliales ) have dramatically shifted. The species of the former family Luzuriagaceae Lotsy were incorporated into the family of Alstroemeriaceae.

The family now includes two tribes with four genera with about 170 species in the Neotropics only by the moderate zones to the tropics:

  • Tribus Alstroemerieae Bernhardi: With two genera and about 165 species: Alstroemeria ( Alstroemeria L.): With about 65 species.
  • Bomarien ( Bomarea Mirb. ): With about 100 to 110 species.
  • Tribus Luzuriageae Bentham & Hooker ( Syn: Luzuriagaceae Lotsy ): With two genera and five species that occur only in the southern hemisphere with a disjunct area: from Peru to Tierra del Fuego and the Falkland Islands, in New Zealand and Australia ( New South Wales to Tasmania ). : Drymophila R.Br.: With two types in Australia: Drymophila cyanocarpa R. Br and
  • Drymophila moorei Baker
  • Luzuriaga marginata ( Gaertn. ) Benth. & Hook. f, Origin: Argentina
  • Luzuriaga parviflora ( Hook. f ) Kunth, Origin: New Zealand
  • Luzuriaga polyphylla ( Hook. f ) J. F. Macbr. ( Syn: L. erecta Kunth ), Origin: Chile
  • Luzuriaga radicans Ruiz & Pav, Origin: Chile, Peru

Use

Varieties of the genus Alstroemeria, are used as ornamentals, especially as cut flowers.

In some species Bomarea the starchy underground plant parts are eaten cooked.
