Tecophilaeaceae

Inflorescence of Conan bifolia

The Tecophilaeaceae are a family in the order of the asparagus -like ( Asparagales ) within the monocot plants ( monocots ).

Description

There are mostly bare, herbaceous plants. Most are geophytes, form the rhizomatous tubers as outlasting. The change-constant leaves are spirally arranged or distichous on the stems or are in some species basal rosette of leaves together. The sessile or sometimes stalked leaves are simple. The parallel venation leaf blade is linear to lanceolate, ovate to roundish. The leaf margin is smooth.

The flowers appear singly or in terminal, simple or often assembled together racemose inflorescences with bracts. The hermaphroditic, flowers are three-fold radial symmetry weakly zygomorphic due to the different sized stamens. The six arranged bloom ( tepals ) are more or less strongly adherent or free. The color of the bloom is yellow or white to purple and blue. There are six intergrown or free, often unequal multiform stamens present; they can be either all fertile or one to three, often up to five are converted to staminodia. The three carpels are usually a half under constant, upper continuous at Walleria ovary adherent to four to fifty ovules per ovary chamber. The upright, straight to slightly curved style ends in a capitate to more or less three-lobed stigma.

The fruit capsules usually contain many small, often black seeds. The cotyledons ( cotyledons ) are not photosynthetically active.

Systematics and distribution

Synonyms for Tecophilaeaceae Leyb. are: Androsynaceae Salisbury, Conantheraceae ( D.Don ) JDHooker, Cyanastraceae Engler, Cyanellaceae Salisbury, Walleriaceae ( R.Dahlgren ) Takhtajan. The Tecophilaeaceae Leyb family. stands near the Ixioliriaceae Nakai family. Lanaria was formerly classified in the family of Tecophilaeaceae but provides its own family Lanariaceae H.Huber ex R.Dahlgren & AEvanWijk today dar.

The family owns a disjoint area: their genera are in Africa, in the southwestern South America and California ( Odontostomum ) ago. They thrive in temperate to tropical climates.

The Tecophilaeaceae family includes about nine genera with about 23 species:

  • Conan Thera Ruiz & Pav ( Syn: Cumingia Kunth ): With three to four species in South America
  • Cyanastrum Oliv. ( Syn: Schoenlandia Cornu ): With about three species in tropical Africa
  • Cyanella Royen ex L. (syn.: Pharetrella Salisb, Trigella Salisb. . ): With about six species in the Capensis.
  • Eremiolirion JCManning & F.Forest: With only one type: Eremiolirion amboense ( Schinz ) JCManning & Mannh. The home is Namibia.
  • Odontostomum hartwegii Torr. in California
  • Zephyra elegans D.Don: The home is Chile.
