Orchid flora of Gunung Ulu Semangko Forest Reserve, Selangor State Park, Malaysia.

摘要: The paper reported preliminary findings on orchid diversity and abundance in Gunung Ulu Semangko, Selangor. A total of 52 orchids taxa belonging to 26 genera were opportunistically sampled from a trail in Gunung Ulu Semangko. The majority of collected species were from the subfamily Epidendroideae, with 47 species (91%). The remaining were from the subfamily Orchidoideae, with five species (9%). The results have shown that most of the species collected were epiphytic, with 42 species (81%) and only ten species (19%) were terrestrial. The orchid species diversity was H= 3.74 for Shannon's Index and D= 0.98 for Simpson's Index. The high D and H values were supported by a high evenness value, E= 0.80, indicating that the abundance of each species was evenly distributed without complete domination by one species. Only two species of orchids were evaluated in the IUCN Red List of Threatened …
