Dimorphorchis
Dimorphorchis is a genus of flowering plants from the orchid family, Orchidaceae. It contains 5 known species, all endemic to Borneo.[1] This genus is known for its dimorphism of flowers and its name is derived from this unique characteristic. In the pendant inflorescences the proximal flowers show a different colouration than the distal flowers. However, this dimorphism is not split equally. The proportion of proximal flowers is significantly smaller than the distal flower morphs. In Dimorphorchis lowii two to three (average of 2.5) proximal flowers and 4 to 18 (average of 11) distal flowers are formed. The vegetative morphology resembles a Vanda species.
