description

Habit of Kabuyea hostifolia with the tubers

They are mostly bare, perennial herbaceous plants . Usually it is geophytes that form rhizome-like tubers as persistence organs. The alternate leaves are arranged in a spiral or two rows on the stems or, in some species, stand together in a basal rosette of leaves . The sessile or sometimes stalked leaves are simple. The parallel-veined leaf blade is linear to lanceolate, ovate to rounded. The leaf margin is smooth.

Flower in detail of Tecophilaea cyanocrocus

The flowers are solitary or in terminal, simple or compound often racemose inflorescences together, with bracts . The hermaphrodite, threefold flowers are radially symmetrical except for weakly zygomorphic due to the different sized stamens . The six identical bloom cladding sheets (tepals) are more or less strongly fused or free. The color of the bracts is yellow or white to purple to blue. There are six overgrown or free, often uneven stamens ; they can either be all fertile or one to three, rarely up to five, have been converted to staminodes . The three carpels are a half under continuous mostly in Walleria Upper permanent ovary grown from four to fifty ovules per ovary chamber. The upright, straight to slightly curved style ends in a cephalic to more or less three-lobed stigma.

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

Systematics and distribution

Synonyms for Tecophilaeaceae Leyb. are: Androsynaceae Salisb. , Conantheraceae (D.Don) Hook. f. , Cyanastraceae Engl. , Cyanellaceae Salisb. nom. cons., Walleriaceae ( R. Dahlgren ) Takht. nom. cons. The family Tecophilaeaceae Leyb. is related to the Ixioliriaceae Nakai family . Lanaria used to be part of the Tecophilaeaceae family, but is now a separate family Lanariaceae H.Huber ex R.Dahlgren & AEvanWijk .

The family has a disjoint area : its genera occur in Africa , in southwestern South America and in California ( Odontostomum ). They thrive in temperate to tropical climates.

The family Tecophilaeaceae comprises about nine genera with about 27 species :

Conanthera Ruiz & Pav. ( Syn .: Cumingia Kunth ): The five or so species are common in Chile .

Cyanastrum olive. (Syn .: Schoenlandia Cornu ): The three or so species are common in tropical Africa.

Cyanella Royen ex L. (Syn .: Pharetrella Salisb. , Trigella Salisb. ): The approximately nine species are common in southern Africa .

Eremiolirion J.C. Manning & F.Forest : It contains only one species:

Eremiolirion amboense (Schinz) JCManning & Mannh. : It is distributed from southwestern Angola to northwestern and central-western Namibia .

Kabuyea Brummitt : It contains only one species:

Kabuyea hostifolia (Engl.) Brummitt : It iswidespreadfrom Tanzania to Mozambique .

Odontostomum Torr. : It contains only one type:

Odontostomum hartwegii Torr. : It occurs in California .

Tecophilaea Bertero ex Colla (Syn .: Phyganthus Poepp. & Endl. , Poeppigia Kunze ex Rchb. , Distrepta Miers ): There are
about two species in Chile and Peru :
- Tecophilaea cyanocrocus Leyb. : It is based in Chile (Santiago).
- Tecophilaea violiflora Bertero ex Colla : It occurs in Peru (Lima) and in Chile from Coquimbo to Santiago.

Walleria J.Kirk (Syn .: Androsyne Salisb. ): The about three species are spread from tropical to southern Africa (Tanzania to South Africa).

Zephyra D.Don (Syn .: Dicolus Phil. ) : The only two species are common in Chile:

Zephyra compacta C. Ehrh. : It was first described in 2001 and occurs in regions III Atacama and IV Coquimbo.
Zephyra elegans D.Don : It occurs from northern Chile to Region IV Coquimbo.
