Studies of the orchid flora on the Mascarene islands (Mauritius, Reunion and Rodrigues) in the South-West Indian Ocean indicate the presence of more than one hundred and fifty species from 38 genera. Only a small number of them are endemic to the island of Mauritius. Habitat destruction over the years has led to the occurrence of several critically endangered species. However, there are still many species that one can observe in specific areas. The most prominent ones are : Angraecum, Bulbophyllum, Cynorkis, Habenaria, Jumellea, Liparis and Polystachia.
