Abstract
We studied pollination biology of three orchids, Dendrobium setifolium, Neuwiedia borneensis and Lecanorchis multiflora, during 1993-1994 in Sarawak. Dendrobium setijolium, a canopy epiphyte, was pollinated by one species of stingless bee, Trigona melanocephala. This may be the first report on stingless-bee pollination of Dendrobium. A primitive orchid, Neuwiedia borneensis, was pollinated by three species of stingless bees which visited flowers for pollen. Autogamy was observed in Lecanorchis multiflora.
