Platycerium ridleyi Christ. : Eksistensi dan Upaya Konservasinya di Kebun Raya Bogor

Abstract

Platyceriunz ridleyi Christ. is an epiphitic fern of the family Polypodiaceae which is potential as an ornamental plant. There is, however, still limited information on its usage, cultivation, and conservation aspects. In 1996 WCMC (World Conservation Monitoring Centre) suggested that the plant is already extinct. But an observation done in the area of Belimbing, Sintang District, West Kalimantan in 1996 showed that the species still exists. In that location it was found some spesimens on a number of trees. Bogor Botanic Garden as an exsitu conservation institution can play an important role in conserving the species. Exploration activzties have been done in rnany places in Indonesia, and from these, Bogor Botanic Garden has collected several specimens from Nyarumenteng, Centre Kalimantan in 1994; in Kedang Ipil, Kutai, East Kalimantan in 1995; and in Sampit, Centre Kalimantan in 1996.
