Notes on fairy orchids (Magnoliopsida: Asparagales: Orchidaceae: Oberonia ) of Sri Lanka: revision in regional distribution and documentation on vegetative propagation

Genus Oberonia Lindley is one of the species rich genera in the family Orchidaceae.  According to the latest literature found in Sri Lanka, there are 50 endemic species, including nine endemics belonging to the genus Oberonia among 184 species in the family Orchidaceae. On comparing it with global level information, a revision of statistics on regional level seems vital.  This short communication discusses the required revision in regional distribution of the genus Oberonia while documenting the first observation of vegetative propagation of the genus Oberonia from Sri Lanka.
