Mycoheterotrophic plants of Gunung Halimun-Salak National Park, West Java, Indonesia

Gunung Halimun Salak National Park (GHSNP) is the largest protected tropical forest in West Java and has high plant diversity, including high diversity ofmycoheterotrophic plants. Mycoheterotrophic plants (MHPs) are aunique group of the plants that have no chlorophyll and their sources of carbon are obtained through a symbiotic relationship with fungi. However, the information on the diversity of MHPs species in the GHSNP region is limited. In this paper, the description, distribution, and ecological preferences of MHPs species of GHSNP are presented. There are 33MHPs species recorded in GHSNP region so far, consisting of 14 species of ferns and lycophytes, 16species of monocotyledons, and 3 species of dicotyledons. From all of these species, one species (Gastrodia crispaJ.J.Sm.) is endemic to Java. Therefore,the forest of GHSNP is important for the conservation ofmany MHPs species.
