Paphiopedilum sanderianum (Rchb. F.) is endemic to Gunung Mulu National Park (GMNP), Sarawak and is listed as an endangered species in the Convention on International Trade in Endangered Species (CITES) Appendix I. Currently there are eight (8) species of slipper orchids found in Sarawak. Endemic to GMNP, Paph.sanderianum is one of the iconic species to the national park. As such, a study was initiated and carried out. This study was to survey the known sites of the species, collect data on individual plant numbers and monitor the phenology aspects of the species. Five locations, namely Green Cave, Paku Waterfall, Berar, Clearwater Cave and Bukit Susu were selected for the study based on Sarawak Herbarium records and information from localcommunity and guides. Berar recorded the highest number of individuals while Paku Waterfall recorded the least number of individual plants. Total percentage of flowering is 32.35% for all five sites in which the flowering season was between July and August. The rate of seedpods production is about 73.36% from thenumber of flowers observed in the previous flowering season.
