Description

The genus Cyrtanthus is highly variable in both the vegetative and in the generative features.

Appearance and leaves

The Cyrtanthus species grow as a perennial, herbaceous plant, reaching very different growth heights depending on the type. Form as outlasting onions which have a diameter of 1 to 5 cm and usually does not protrude from the ground. The bulbs often produce many daughter bulbs. They are either evergreen ( Cyrtanthus brachysciphus, Cyrtanthus elatus, Cyrtanthus epiphyticus, Cyrtanthus herrei, Cyrtanthus montanus, Cyrtanthus obliquus, Cyrtanthus obrienii, Cyrtanthus ochroleucus, Cyrtanthus staadensis ) or are geophytes, in which, during the dry season dry up the leaves and fresh leaves only after the cast heyday again. Among the geophytes, there are species that are green in the South African summer and another in winter.

The depending on the type few to many only basal, erect to spreading leaves are sessile. The simple leaf blades are linear to strap- shaped, sometimes turned upside down to spiral. The leaf surfaces are bare and the blade edge is smooth. The midrib is often significantly elevated and there is Parallelnervigkeit ago.

Inflorescence and flowers

The most hollow, barren inflorescence stem is erect. Depending on the type are one to many flowers together in an often constructed loosely, doldigen inflorescence. In knospigen state envelop two to four narrow - lanceolate, membranous bracts ( spathe ) and has the inflorescence, they wither early during anthesis. The flowers are on a cover sheet ( Brakteolen ) respectively. The upright to hanging flower stalks are most equal in length to the perianth.

In some species smell the flowers. The depending on the nature very different sized flowers are hermaphrodite, rarely radial symmetry, usually somewhat zygomorphic and threefold. The six identically shaped bracts are grown on more than half of their length to an often curved tube that is more or less widened at their base. The perianth is tubular or trumpet- shaped. The color of the bloom ranges from white to yellow to orange and red to pink. There are two circles, each with three equal, stamens present, which can project beyond the perianth. The stamens are usually among themselves free or rarely fused with a broadened base and then form a corona. The anthers are dorsifix or rarely pseudo- basifix and move freely. Three carpels are fused to an almost spherical, dreikammerigen, inferior ovary. Each ovary chamber contains many (10 to 30) ovules. The upright, straight pen is as long or longer than the stamens and may project beyond the perianth; He ends with a short to clearly three-lobed stigma.

For some species, the English common name "fire lily" is used, it is for example for Cyrtanthus contractus, Cyrtanthus ventricosus and Cyrtanthus odorus also a very fitting name. This species bloom very quickly after bushfires. From Cyrtanthus ventricosus is known to have flourished nine days after a bush fire and Cyrtanthus odorus is believed that it blooms in nature only by bush fires.

For most types of Cyrtanthus the heyday of the South African late summer reaches up to mid-autumn. Exceptions are, for example Cyrtanthus galpinii whose heyday of early enough by the end of the South African winter, and Cyrtanthus falcatus that blooms in early spring.

For species of the genus Cyrtanthus there are many different pollinators. The summer and autumn red flowering species are pollinated by large butterflies ( from the subfamily of Julia Butterfly ( Satyrinae ), for example Aero Petes tulbaghia ). In species with red, tubed flowers are sunbirds ( Nectariniidae ) pollinators. Moths pollinate species (eg Cyrtanthus mackenii ) with fragrant flowers and engröhrigen. Bees and flies were observed langrüsselige as pollinators.

Fruit and seeds

The more or less ellipsoidal, lokulizidalen fruit capsules open with three to zurückkrümmenden fruit flaps. The black seeds are flattened, winged wrinkled and usually a little bit.

Chromosome number

The basic chromosome number of x = 8, it differs Cyrtanthus of most genera of Amaryllidoideae from.

Occurrence

The genus Cyrtanthus is widespread in sub-Saharan countries on the African continent. 22 species are elements of Capensis. In the Eastern Cape, most species occur.

Most species thrive in the humid climate of the eastern portion of Southern Africa. Only six species date back to the summer dry area of ​​southwestern capensis. To the north, to East Africa reach only two ways.

Systematics and endangering the species

The genus name Cyrtanthus was first published in 1789 by William Aiton in Hortus Kewensis, 1 S. 414. As Lectotypusart 1951 Cyrtanthus angustifolius Aiton by Edwin Percy Phillips in The Genera of South African Flowering Plants, 2nd edition, p 204 has been set. A homonym is published by Johann Christian Daniel Schreber in Genera Plantarum, 1789, p 122 in the same year name Cyrtanthus Schreb .. This was in Vienna ICBN Art 14:10 & App. III set. Synonyms of Cyrtanthus Aiton are: Anoiganthus Baker, Gastronema Herb, Herb Monella, Vallota Salisb. .. ex Herb ... The genus name Cyrtanthus derives from the Greek words kyrtos for curved and anthos for flower from, this refers to the curved corolla tube Cyrtanthus of many species.

Cyrtanthus is the only genus of the tribe Cyrtantheae Salisb. in the subfamily Amaryllidoideae within the family of Amaryllidaceae. Previously, she was also classified in the family Liliaceae.
