The Hohenbergia are a genus of the subfamily Bromelioideae in the family Bromeliaceae ( Bromeliaceae ). In this genus there are about 54 species.
Dissemination
The genus has a disjunct distribution: some species occur only in the West Indies (especially Jamaica ), which most other types have their areas in Brazil, there are also species in Guatemala.
Because of their size is rare to find these types in private collections in areas where they can not be maintained in the open air by the occurrence of frosts. But in some tropical parks and gardens and also in almost all botanical gardens you will find this relatively undemanding but decorative plants, most commonly Hohenbergia stellata.
Description
The Hohenbergia species are hopper or tank bromeliads. There are usually large species with more than 1 m funnel diameters and inflorescences, which are high above 1 m. Most species are epiphytes. The rough leaves are always on the verge armored ( like all members of the Bromelioideae ), with a spiked tip, Saugschuppen are mainly seen on the underside of leaves. In the leaf hoppers often collect large amounts of water. In many craters there are small habitats with more species of algae and aquatic plants.
The flowers sit on many of the most respectable, long-lasting inflorescences ( inflorescences ), they are composed of peg-shaped part inflorescences. At the inflorescences often sit bright colored bracts ( bracts ); it dominates the color red (mostly with a blue component ), there are also white.
