Diversity of Pandanus spp. in Wetland Area of Kalimantan

Bornean Pandanaceae has been thoroughly studied by Stone since 1967. Fifty three species of Pandanus have been reported in 1993. Most of those species recorded from the North of Borneo (Sabah, Sarawak and Brunei) as endemic species. Recently, based on herbarium specimens study, nine species of Pandanus spp. recorded from wetland area of Kalimantan. Three species are accounted as new records, namely P. sigmoideus, P. vinaceus and P. yvanii. Two species formerly recorded endemic to Sarawak whereas P. yvanii formerly endemic to Malay Peninsula. Two species recorded as endemic to Borneo are P. motleyanus and P. discostigma. Whereas the rest of the species – P. affinis, P. aristatus, P. helicopus and P. korthalsii, have more wide distribution compared with other species and can be found in rain forest of West Malesia region. An identification key to species and their descriptions are presented. Proceeding of the International Workshop on Sustainable Management of Bio-Resources in Tropical Peat-swamp Forest. Hal. 141-149
