It is estimated that over 3,000 species of orchids can be found in the wild in Borneo. However as the "wild places" of Borneo shrink many of these treasures, together with countless other plants and animals will inevitably become lost. One previously common fragrant orchid is the Necklace Orchid - Coelogyne rochussenii which is usually found growing on trees, sometimes rocks, overhanging rivers. Due to land clearing, river banks are now mostly treeless and so this orchid is now more often seen in somebody's garden!
Like the common Pigeon Orchid this orchid only flowers occassionally but when it does the whole neighbourhood would be filled with a very strong and sweet scent. However unlike the flowers of the Pigeon Orchid, the blossoms and scent of the Necklace Orchid last for over a week.
Coelogyne rochussenii (which was named after the wife of a certain Monsieur Rousseau who was a French Orchid Enthusiast in the 1800s) is also found in most of Southeast Asia, including Thailand, Peninsular Malaysia, Sumatra, Java, Sulawesi, and the Philippines.
