Some endemic plants found in the Roraima |
| Endemismo: The summit of the Roraima represents a difficult atmosphere for any alive organism. The naked rock is low in minerals and poor in nutritious (especially match, calcium and nitrogen), the crowd is sour and it lies directly on the rock, any nutrient is washed quickly by the water of the rains and the floors are constantly erosionados for quick floods. Some plants have had to develop mechanisms for suplementar their diets, other, others they have developed special abilities to avoid the lost of water for evaporation (due to the high radiation), as well as to be able to be sustained indeed in so thin and inadequate substratum. in the same way, the animals are forced to survive in such atmospheres with a limited quantity of foods and in extreme conditions of radiation and temperature. . |

Droseraceae (Drosare Roraime) it is a family of plants of the order Caryophyllidae. It plants insectivorous, when the small insects settle on them they are caught by a sticky substance that you/they secrete their glandular hair then of which cannot escape, they extract him the necessary nutrients and they discard the rest. this way they are able to subsist in places of extreme conditions, in floors lacking nutritious as in the summits of the tepuyes. |
 |
 |
Heliamphora Nutans (Sarraceniaceae) It plants carnivorous terrestrial endemic of the tepuyes. Its name in Latin means "jar of the swamps". it Grows forming dense heaps in the humid places. Their leaves of red color, form kind of a "jar" or Tube to foliate with which collect the water of the rain, and that it is good him at the same time to catch unaware insects that can come closer too much. Their delicate white flowers hang in the high of a red shaft. |
 |
Stegolepis Guianensis (Rapataceae) Endemic gender of the tepuyes with several represented. This family is also in Africa, suggesting this way an I link via Gondwana. It is a dominant plant in the summit tepuyana, being easily recognizable for their brilliant green leaves in fan form and for some pointed yellow inflorescences that are in the high of a long shaft like in form of "magic twig" |

 |
Epidendrum secundum (Orchidaceae) The Orchids belonging to the botanical family of the Orchidaceae, understand 25.000 approximately (some sources inform of 30.000) species, and maybe other 60.000 hybrid and varieties taken place by horticulturists. Extended all over the world, but particularly abundant in the tropical regions. Commonly they call themselves orchids. Due to their floral complexity, to their interactions with the agents polinizadores and to their symbioses with mushrooms to form micorrizas, they are considered as the culmination of the floral evolution |

Aphanocarpus steiermarkii |
 |
Catopsis Berteriorana. Bromelia of lengthened leaves of yellowish green color that grows in the branches of other near bushes, in a tangle like a cotton their seeds vanish for the wind and they are caught in the near bushes where these plants in a parasitic way grow. |
|
 |
Ledothamnus Guianensis | |
 |
Brocchinia Tatei y reducta (Bromeliaceae) The species B. reducta is an easily recognizable insectivorous bromelia because its leaves form a tube to foliate high and thin resemblance to that of the Heliamphora and with which collects rain water and it catches insects for suplementar its diet. The intense greenish yellow color of its leaves attracts the insects, some of those which, finally he/she falls in its glass and they drown, being digested by means of some special cells located in the base of the leaves. The species B. tatei, grows but conventionally, forming its leaves wide rosetas of greenish yellow color. The gender Brocchinia is endemic of the Guiana. |

The plants of the summit of the Roraima cling precariously to the life amid cracks and cliffs of the surface erosionada where he/she wants that the thin and scarce floor escapes from being dragged by the strong and constant rains. In areas exposed, small mattresses of endemic vegetation they form beautiful groups that seem true "Japanese Gardens". In Roraima it exists a great variety of plants and flowers, the endemic majorities of them of the tepuyes. | |

Oreophrynella Quelchii. It is a very curious frog of the endemic gender of the tepuyes, it is a very old species that he/she has not forced her to radically evolve had been able to conserve many of their primitive characteristics since the atmosphere. It is much more related with some frogs africanasque with those opposing ones in Suramérica (what suggests an old bond with the Gondwana). This is of black color and their stomach is of orange color. It is not he possible to jump but if to walk or to crawl. If it is afraid, it remains still in the rock where you "he/she makes the dead one". Alone it exists in the tepuyes but high, and the are sufficiently differed as to be considered different species. |
