According to Dorothy S. Dunn de Araujo and Raimundo P. B. Henriques, in "Análise Florística das Restingas do Estado do Rio de Janeiro" (Floristic Analyse of the Sandbanks of the State of Rio de Janeiro) (published in l984), the following species of Orchidaceae family grow in the restingas (sandbanks) of the state of Rio de Janeiro (Cabo Frio, Araruama, Maricá, Itaipu, Jacarepaguá, Grumari and Marambaia):
Dorothy Sue Dunn de Araujo, ecologist, whose doctorate thesis is entitled "Análise florística e fitogeográfica das restingas do Estado do Rio de Janeiro" (Floristic and Phyto-geographic Analyse of the Sand-banks of the State of Rio de Janeiro de Janeiro), based on her own researches in field, in herbariums and bibliography, confirmed the occurrence in the restingas of the state of Rio Janeiro which were not included in the list above. We can also verify the disappearance of some others (list updated in September 2001)

The restingas (Sandbanks) are located in the coastal plains which are formations originated by sediments due to different factors, mainly the oscillations of the sea level and the climatic changes. Those sediments have many forms and one of them is called "coastal cord", formed by maritime sediments (constant depositions of sands) originating bunches of sandbanks showing the progressive rise and the fall in the level of the sea. They are recent geological formations, submitted to the continental and marine actions.

In the state of Rio de Janeiro, those cords start since Itabapoana (in the boundary of the state of Espírito Santo) until the Trindade beach, going across Macaé, lakes region (Arraial do Cabo, Cabo Frio, Araruama) and Rio de Janeiro city, since the north until the south of the state.

Some of those restingas are well known such as Massambaba restinga which separates Araruama lagoon from the sea and Marambaia restinga (45km. lenght), as it is occupied by the Army, the access is more restrict, thus it is quite preserved. It is consisted by narrow and discontinued strips with very fine white sand, covered by a sparse vegetation, crawling herbs and few shrub. The soil has a high-grade of salinity

Marapendi area (in Rio de Janeiro city) has loose the characteristic by the drawing of Sernambetiba avenue. The restingas former existing in the quarters of Botafogo, Governador Island, Copacabana, Ipanema, Leblon and a great part of Barra da Tijuca and lowlands of Jacarepaguá have been destroyed by the expansion of habitations.

The origin of the lagoons is related to the formation of those coastal cords. The coastal cord known as Massambaba restinga with 50km long originated Araruama lagoon.
On the other hand, Marambaia restinga, with 40 km long de originated the bay of Sepetiba.
In the edges of those lagoons or bay, the sediments originated by the action of the fluxes of the water that go down from the neighbouring mountains.

The vegetation of restingas is called pioneer formations (as well as those from the mangrove, beaches and dunes).
This is a vegetation of first occupation in a area where the soils are continually submitted to the maritime, fluvial and fluvial-marine influences (arboreous and herbaceous vegetation).

The vegetation is not regular and is presented in bushes shape, under the form of sparse fields of grass, dense woods with 12m height or swamps areas. There are the external sandy cord or external sandbank (next to the sea), internal sandy cord or internal sandbank, next to the lagoon and between both, there is a swampy area, covered with dense organic material. Except to the swampy area, the soil does not retain the humidity because it is very sandy, not being in this way the mainly source of nutrients.

The restingas are, in general, little exposed to rains and are hit by the wind that blows daily and the ocean (in this case, the Atlantic) exercises an important role of thermal regulator with a strong power of elevating the humidity of the air.
The two mainly restingas of the state of Rio de Janeiro have a great difference:
Massambaba restinga is, in the bigger part, located in area with demi-humid regime from 4 to 6 dry months, a small fraction in dry regime (from 7 to 10 dry months) and extremely dry (from 11 to 12 dry months).
On the other hand, Marambaia restinga in a area of very humid regime (no dry month) and humid (from 1 to 3 dry months).
Both are situated in a thermal regime considered hot, it means, they do not present an average temperature during the coldest days, above 18º C.
Those factors determine the specialisation of the vegetation making it tolerates the strong drought periods or excessive humidity.

Some areas are under protection of the Government (Federal, of the municipality or the State) as unity of conservation, nevertheless, they endure the same problems the others non-protected areas. In all of them, the mainly problems involve the pollution of the water by the domestic sewerage systems, illegal extraction of sand and plants, degradation of areas reserved to preservation and archaeological sites, irregular and illegal occupation of the strip of the lagoon shore, deforestation and burning, illegal hunting, the accumulation of any kind of refuse, degradation of the vegetation by the jeeps and other vehicles of vacationists mainly during the high season.

All information has been done just for curiosity, with the purpose of helping to understand a little more about the habitat of those species.
