Ronnbergia
Ronnbergia petersii
Ronnbergia is a plant genus of the subfamily Bromelioideae within the family Bromeliaceae ( Bromeliaceae ). The range extends from Costa Rica to Colombia, northern Peru and Brazil.
Description
The Ronnbergia species are epiphytic and terrestrial living, evergreen, perennial herbaceous plants. They form by stolons stocks. Some species look similar Neoregelia species. Derbe leaves sitting on a compressed stem axis and form the funnel, where often water is collected. The simple, parallel venation, tongue-shaped leaves have smooth to spiny toothed leaf margins. In some species the leaves above the leaf sheath are narrowed stalk -like. The leaf surfaces are simply drawn and have green or on the underside of leaves pressed- dandruff hair.
The inflorescence stem is often more or less short, which has little or no surmounted in some species (eg Ronnbergia neoregelioides, Ronnbergia nidularioides, Ronnbergia petersii ) of the inflorescence leaf hopper. The bracts are usually inconspicuous. The simple, eared inflorescence is dense to loose. The sessile, pentacyclic ( five petal circles), hermaphroditic, radial symmetry blooms are triple. The three most blue petals do not have scales at their base. Three carpels are fused into one inferior ovary.
Flowers formula:
The at maturity often intensely colored berries contain numerous seeds. A peculiarity occurs in Ronnbergia blow dens, giving her epithet rather because its ripe berries with a loud bang, so explosively detached from and spray out the slimy coated seeds.
System
The genus Ronnbergia was built in 1874 by Charles Jacques Édouard Morren and Édouard François André horticole in L' illustration, 21, pp. 120 set up with the type species Ronnbergia morreniana Linden & André. The botanical genus name Ronnbergia honors the director for agriculture and horticulture in the Belgian Ministry of the Interior Auguste Ronnberg.
There are about 14 species Ronnbergia:
- Ronnbergia campanulata Gilmartin & H.Luther: It is native to Ecuador. This growing terrestrial endemic only on the type of site in the Cordillera del Cóndor northwestern above the Río Zamora known. It has been found since 1972, no further time and the area of distribution appears to be very small, while the area is affected by logging. This leads to a classification in the IUCN Red List as endangered ( Endangered ).
- Ronnbergia carvalhoi Martinelli & Leme: It's home in Brazil.
- Ronnbergia columbiana E.Morren: It comes from Colombia to northern Peru before.
- Ronnbergia deleonii L.B.Smith
- Ronnbergia blow dens LBSmith: From this terrestrial in the cloud forest thriving type localities in Panama and northern Peru are known.
- Ronnbergia hathewayi LBSmith: It is native to Costa Rica.
- Ronnbergia killipiana LBSmith: It is native to Colombia.
- Ronnbergia maidifolia Mez: It is native to Panama and Colombia.
- Ronnbergia morreniana Linden & André: It is native to Colombia.
- Ronnbergia neoregelioides Leme: It is native to the Brazilian Atlantic Forest.
- Ronnbergia nidularioides H.Luther
- Ronnbergia petersii LBSmith: It is native to Panama.
- Ronnbergia silvana Leme: It is native to Brazil.
