Distribution et richesse taxonomiques des épiphytes de quelques phorophytes au Parc national de Korup (Cameroun)
The study of vascular epiphytic flora of Korup National Park has been carried out in 50 hectares of the Korup Forest Dynamics Plot (KFDP). The sampling used Johansson's method  of over 100 phorophytes belonging to five species of which each species is made up of 20 individuals of the same species. A collection was made through KFDP. It was noted that a total of 154 species where 19 Pteridophytes (12.33 %), 10 Dicotyledons (6.49 %) and 125 Monocotyledons (81.17 %) were thus registered. These epiphytes were divided into nine families and 46 genera. The families of greater abundance are Orchidaceae with the species of 66.23%, Araceae with the species of 14.94% and Polypodiaceae with the species of 5.84%. Other important family is egoniaceae with the species of 5.19%. The genus Bulbophyllum is the most abundant; it is represented by the species of 22.07%. The analysis of flora, thanks to the statistical test, shows that Oubanguia alata, Cola praecuta and Strephonema pseudocola are floristically the same. The vertical distribution shows that, the II, III and IV levels of Johansson  are those mostly represented.
